Surgical management of moderate ischemic mitral valve regurgitation: Where do we stand?

2014

Ischemic mitral regurgitation (IMR) represents a common complication after myocardial infarction. The valve is anatomically normal and the incompetence is the result of papillary muscles displacement and annular dilatation, causing leaflets tethering. Functionally the leaflets present a restricted systolic motion due to tethering forces that displaces the coaptation surface toward the left ventricle apex. The patients present poor left ventricular function at the time of surgery and the severity of the mitral regurgitation increases the risk of mortality. Currently there is general agreement to treat surgically severe IMR nevertheless strong evidences for patient with moderate insufficiency…

The effect of off-pump coronary artery bypass on mortality after acute coronary syndrome: A meta-analysis

2012

Background Patients requiring surgical revascularisation for acute coronary syndrome (ACS) form a clinically heterogeneous group ranging from haemodynamic stability to cardiogenic shock. Whilst 'off-pump' revascularisation (OPCAB) is often considered, patient selection and operative timing remain controversial. This study aims to identify whether OPCAB may confer a mortality benefit over ONCAB in revascularisation for ACS. Secondly, we review the impact of OPCAB on completeness of revascularisation (CR) and long-term re-intervention. Methods A systematic literature review identified 9 studies (1 randomised controlled trial) of which 8 fulfilled criteria for meta-analysis. Outcomes for a tot…

Mitral valve therapy still surgical?

2015

Mitral regurgitation (MR) is the second most common valvular heart disease after aortic valve stenosis. With increased understanding of the heterogenic pathophysiology of MR, cardiac surgeons have developed various techniques that increase the likelihood of successful mitral valve repair (MVR). Nowadays, a rate of repair >90% may be reached in some mitral valve reference centres. In recent years, the introduction of transcatheter mitral valve intervention techniques has opened up new frontiers in mitral therapy, specifically in patients at high risk for standard surgery. Current percutaneous technologies for MVR have been developed on the basis of some of the surgical principles. Based on c…

Long Term Results After Repair of Type A Acute Aortic Dissection According to False Lumen Patency.

Results of mitral valve repair for Barlow disease (bileaflet prolapse) via right minithoracotomy versus conventional median sternotomy: a randomized …

2011

Objective: The results of mitral repair for complex Barlow valves are adequate and support earlier intervention. It is unknown whether these results are reproducible in the context of minimally invasive surgery via right minithoracotomy. Methods: We randomized patients with Barlow mitral disease (bileaflet prolapse) to have conventional open repair via median sternotomy (MS group) or minimally invasive (MI group) repair. Repair was done using polytetrafluoroethylene chordal reimplantation for both leaflets. In the MI group, we adopted right minithoracotomy, peripheral cannulation, external aortic clamping, and surgery under direct vision. Results: Both groups comprised 70 patients. The oper…

Papillary muscle relocation in conjunction with valve annuloplasty improve repair results in severe ischemic mitral regurgitation

2012

OBJECTIVE: The incidence of recurrent mitral regurgitation (MR) after restrictive annuloplasty (RA) was 5% to 20% in several reports. There are many opinions in favor of adding subvalvular procedures to RA to reduce the tenting forces and improve the repair results. METHODS: From March 2003 to May 2010, 55 patients with severe ischemic MR who had undergone papillary muscle (PPM) relocation in conjunction with mitral annuloplasty in our institutions were enrolled. The patients were matched 1:1 with those who underwent isolated RA using the propensity score. The mean left ventricular ejection fraction was 42% ± 6%. The mean tenting area and coaptation depth was 3.2 ± 0.6 cm(2) and 1.3 ± 0.2 c…

Therapeutic decision-making for patients with fluctuating mitral regurgitation

2015

Mitral regurgitation (MR) is a common, progressive, and difficult-to-manage disease. MR is dynamic in nature, with physiological fluctuations occurring in response to various stimuli such as exercise and ischaemia, which can precipitate the development of symptoms and subsequent cardiac events. In both chronic primary and secondary MR, the dynamic behaviour of MR can be reliably examined during stress echocardiography. Dynamic fluctuation of MR can also have prognostic value; patients with a marked increase in regurgitant volume or who exhibit increased systolic pulmonary artery pressure during exercise have lower symptom-free survival than those who do not experience significant changes in…

Association between asymptomatic carotid atherosclerosis and degenerative aortic stenosis.

2012

OBJECTIVE: Degenerative aortic stenosis shows similarities with atherosclerosis. To confirm the hypothesis that aortic stenosis is an "atherosclerosis-like" disease, we investigated the association between degenerative aortic stenosis and atherosclerosis of carotid arteries. METHODS: We studied 270 consecutive patients, 135 with degenerative aortic stenosis (trans-aortic peak velocity ≥ 2 m/sec) and other 135 subjects without aortic valve disease. All patients underwent echocardiography and ultrasound scan of the supra-aortic trunks to assess the presence of plaque and/or intima-media thickening (IMT). RESULTS: Atherosclerosis of carotid arteries (IMT and plaque) was significantly more freq…

2016

Background Postprocedural aortic regurgitations following transcatheter aortic valve implantation (TAVI) procedures remain an is- sue. Benefit of oversizing strategies to prevent them isn’t well established. We compared different level of oversizing in our cohort of con- secutive patients to address if severe oversizing compared to normal sizing had an impact on post-procedural outcomes. Methods From January 2010 to August 2013, consecutive patients were referred for TAVI with preoperative Multislice-CT (MSCT) and the procedures were achieved using Edwards Sapien® or Corevalve devices®. Retrospectively, according to pre-procedural MSCT and the valve size, pa- tients were classified into thr…

Mid-term results of bicuspid aortic valve repair guided by morphology and function assessment.

2016

Bicuspid aortic valve (BAV) is frequently associated with aortic insufficiency (AI) due to cusp disease and/or aortic root dilatation. Based on functional classification and morphology, a systematic surgical approach was used for aortic valve repair (AVr).From 2004 to 2014, 152 consecutive patients (mean age 55 ± 7 years) with BAV underwent AVr with or without concomitant aortic root surgery. Cusp pathology was treated with central plication in 60 (39.5%) patients, free edge reinforcement in 45 (29.6%), triangular resection in 28 (18.4%) and pericardial patch in 19 (12.5%). Aortic root dilatation was corrected with valve sparing reimplantation in 65 patients. Mean follow-up was 68 ± 36 mont…

A Comparison of 2 Mitral Annuloplasty Rings for Severe Ischemic Mitral Regurgitation: Clinical and Echocardiographic Outcomes.

2016

Controversies regarding the choice of annuloplasty rings for treatment of ischemic mitral regurgitation still exist. Aim of the study is to compare early performance of 2 different rings in terms of rest and exercise echocardiographic parameters (transmitral gradient, systolic pulmonary artery pressure, and mitral valve area), clinical outcomes, and recurrence of mitral regurgitation. From January 2008 till December 2013, prospectively collected data of patients who underwent coronary artery bypass grafting and undersizing mitral valve annuloplasty for severe chronic ischemic mitral regurgitation at our Institution were reviewed. A total of 93 patients were identified; among them 44 had sem…

Short-term and long-term results of cardiac surgery in elderly and very elderly patients

2011

Objective: Cardiac operations in elderly patients are increasingly frequent and imply major clinical, ethical, and economic issues. Operative and 5-year results of cardiac operations in patients aged 79 years or more are known in limited series, and a debate is ongoing on the appropriateness of selection of patients for surgery. Methods: We retrospectively reviewed our experience in 6802 patients aged 79 years or more who had received a cardiac operation. Surgical candidates were selected according to functional status, crude operative risk, and social context and were managed according to a multimodality protocol. Results: Mean age was 82 years and surgery was nonelective in 1613 cases (23…

An update on the role of markers of inflammation in atherosclerosis

2009

In recent years, several studies have used the measurement of carotid intima-media thickness (IMT) as a marker of early atherosclerosis: IMT has been shown to correlate significantly with the presence of coronary artery disease (CAD) and to predict fatal and not fatal cerebro- and cardio-vascular events. These findings highlight the importance of recognizing and managing early stages of atherosclerosis for effective cardiovascular prevention. Beyond traditional established cardiovascular risk factors, inflammation has been shown to be crucial throughout atherosclerosis from endothelial dysfunction to plaque rupture and thrombosis. Several studies have shown the existence of a strong relatio…

Transapical beating-heart chordae implantation in mitral regurgitation: a new horizon for repairing mitral valve prolapse

2016

Mitral regurgitation (MR) is increasingly prevalent in western countries despite reduced incidence of rheumatic disease (1,2). MR results from several heterogeneous conditions, including disorders of the valve leaflets, mitral annulus, chordae tendineae, papillary muscles and left ventricle (LV). MR causes are roughly classified as primary (i.e. organic/structural) or secondary (i.e. functional/non-structural) (3).

Atherosclerosis, degenerative aortic stenosis and statins

2009

Aortic stenosis is the most common valvular heart disease among adult subjects in western countries The current treatment for aortic stenosis is aortic valve replacement. The possibility of a medical treatment that can slow the progression of aortic stenosis is very fascinating and statins have been tested to reduce the progression of degenerative aortic stenosis (DAS). The rationale for statin treatment in DAS has a deep pathophysiological substrate, in fact inflammation and lipid infiltration constitute the same histopathological pattern of both aortic stenosis and atherosclerosis and these two conditions have the same risk factors. Whether retrospective studies have shown some efficacy o…

Histological and genetic studies in patients with bicuspid aortic valve and ascending aorta complications.

2011

OBJECTIVES: Aneurysm diameter and growing rate does not represent a definite parameter for operation in bicuspid aortic valve (BAV), ascending aortic aneurysm and normal root patients. Thus, we investigated histological and immunohistochemical aspects of different segments of ascending aorta (precisely, aortic root without dilatation, aneurysmatic tubular portion, dissected ascending aorta) and genetic features of patients with BAV and ascending aorta complication (aneurysm or dissection). METHODS: Aorta tissue samples of 24 BAV patients were examined. The patients comprised of 18 men and 6 women; the mean age was 54.2 ± 14.3 years. All patients underwent composite aortic root replacement (…

Aortic valve-sparing root replacement from inside the aorta using three Dacron skirts preserving the native Valsalva sinuses geometry and stabilizing…

2009

We present an alternative idea for valve-sparing technique combining the advantages of the reimplantation and the benefits of the remodeling techniques. We replace the sinuses of Valsalva using three Dacron skirts from inside of the aorta. The physiological anatomy of the Valsalva sinuses and their dynamic properties are preserved and the aortic commissures displacement avoided. The distal rim of each Dacron skirt was anchored to the aorto-ventricular junction using Ticron (2-0) U stitches placed from the ventricular side to the aortic side. We stabilize the base of the aortic annulus to prevent future dilation.

Minimally invasive mitral valve surgery: State-of-the-art and our experience

2015

The minimally invasive approach is becoming the standard-of-care for surgery of the mitral valve. As any less invasive strategy, it entails an increased surgical complexity. Standard-of-care mitral repair using the totally videoscopic approach is indeed reproducible; however, few specific data on patients with complex mitral valve disease are available in the published literature. The purpose of the present paper is to provide an overview of the current state-of-the-art in minimally invasive cardiac surgery, and a summary of recent evidence on the topic, with particular regard to the surgical techniques and comparisons with conventional surgery. The experience of the GVM Care and Research n…

Multimodality imaging strategies for the assessment of aortic stenosis: Viewpoint of the heart valve clinic international database (HAVEC) group

2016

International audience; Aortic stenosis is the most frequent valvular heart disease. In aortic stenosis, therapeutic decision essentially depends on symptomatic status, stenosis severity, and status of left ventricular systolic function. Surgical aortic valve replacement or transcatheter aortic valve implantation is the sole effective therapy in symptomatic patients with severe aortic stenosis, whereas the management of asymptomatic patients remains controversial and is mainly based on individual risk stratification. Imaging is fundamental for the initial diagnostic work-up, follow-up, and selection of the optimal timing and type of intervention. The present review provides specific recomme…

Implantation of Gore-Tex chordae on aortic valve leaflet to treat prolapse using "the chordae technique": surgical aspects and clinical results.

2008

Background Repair of prolapsed aortic valve leaflets has been considered a challenging technique for cardiac surgeons. In this paper we describe our surgical approach, "the chordae technique." It consists of the correction of aortic cusp prolapse by shortening the free margin length and of an adjustment of the leaflets coaptation height by anchoring the prolapsing cusp to the aortic wall at the sinotubular junction level. Methods Between February 2003 and December 2006, 26 patients with one or more prolapsed aortic leaflets underwent surgical repair using the new approach. The mean age of patients was 55 ± 10 years. There were 10 (38.5%) patients with grade II aortic valve regurgitation, 4 …

Aortic Annulus Stabilization Using Internal Rings

2017

The past 20 years have seen the growing range of valve lesion etiologies turn nonvalvular conditions into the primary causes of aortic regurgitation [1]. Valves present relatively small lesions of the leaflets and concomitant dilatation of the ascending aorta with aortic regurgitation that can be explained thanks to our improved knowledge of the functional aortic annulus’ role in valve function. The geometric relations and dynamic behavior of aortic root components have been seen to ensure valve competence when leaflets have no structural lesions [2].

Contrast-induced Nephropathy after Percutaneous Coronary Intervention in Simple Lesions: Risk Factors and Incidence are Affected by the Definition Ut…

2011

Aim To compare the incidence, and risk factors, in-hospital and at the 18-month prognosis of contrast-induced nephropathy (CIN) according to the definition utilized: as an increase in serum creatinine (Scr) ≥0.5 mg/dL (CIN 1) or as an increase in Scr ≥25% above baseline values (CIN 2). Methods and Results We prospectively evaluated CIN according to two different definitions in 150 patients who underwent percutaneous coronary intervention (PCI) in simple lesions employing a low-medium dose of contrast media. Incidence of CIN was higher using the CIN 2 definition than CIN 1 (9.3% vs. 4%; p=0.0133). Patients with CIN 1 had a higher incidence of chronic kidney disease (CKD) (66.7% vs. 13.9%; p=…

Multiplane Two-Dimensional versus Real Time Three-Dimensional Transesophageal Echocardiography in Ischemic Mitral Regurgitation

2011

Objectives: Intraoperative three-dimensional (3D) transesophageal echocardiography (TEE) has been suggested to be a valuable technique for the evaluation of the mechanisms of ischemic mitral regurgitation (IMR). Studies comparing multiplane two-dimensional (2D) with 3D TEE reconstruction of the mitral valve using the new mitral valve quantification (MVQ) software are lacking. We undertook a prospective comparison between multiplane 2D and 3D TEE for the assessment of IMR. Methods: We evaluated echocardiographically 45 patients with IMR who underwent mitral valve surgery in our institution. 2D and 3D TEE examinations followed by a 3D offline assessment of the mitral valve apparatus were perf…

RUPTURE OF AN AORTIC DISSECTION INTO THE RIGHT ATRIUM IN A PATIENT WITH PREVIOUS AORTIC VALVE REPLACEMENT: A CASE REPORT

2005

We report the case of a 73-year-old man with a history of previous aortic valve replacement in 1990 and rupture of an aortic dissection into the right atrium. The patient was admitted to the emergency room because of chest pain, stopped not long after. The electrocardiogram did not show any signs of ischemia and myocardial enzymes were not increased. Transthoracic echocardiography revealed aortic root dilation (maximum diameter 60 mm) extended to the aortic arch, and the presence of a flow from the ascending aorta to the right atrium (evocative of a fistula between the two chambers). The aortic valvular prosthesis function was good. Transesophageal echocardiography confirmed an aorta-right …

Minimally invasive aortic valve surgery

2016

Aortic valve disease is a prevalent disorder that affects approximately 2% of the general adult population. Surgical aortic valve replacement is the gold standard treatment for symptomatic patients. This treatment has demonstrably proven to be both safe and effective. Over the last few decades, in an attempt to reduce surgical trauma, different minimally invasive approaches for aortic valve replacement have been developed and are now being increasingly utilized. A narrative review of the literature was carried out to describe the surgical techniques for minimally invasive aortic valve surgery and report the results from different experienced centers. Minimally invasive aortic valve replacem…

SIMPLE, SAFE AND EASY TECHNIQUE TO ENSURE THE CORRECT LENGTH OF ARTIFICIAL CHORDAE IN MITRAL VALVE REPAIR.

2007

Replacement of diseased chordae with Gore-Tex sutures (W. L. Gore & Assoc, Flagstaff, AZ) in patients with degenerative mitral valve insufficiency has become a standard technique used by surgeons in mitral valve repair with good long-term results. Nevertheless, determining the correct length of the artificial chordae has remained problematic. Although various procedures have been previously published, in this article we describe our approach used to achieve an accurate chordal height adjustment.

Shedding some light on tricuspid intervention

2021

Background More than 1.6 million Americans have at least moderate to severe valvular tricuspid regurgitation, yet fewer than 8000 tricuspid valve operations are performed annually in the USA. The undertreatment for isolated tricuspid regurgitation might be related to the fact that in the past years no clear guidelines on 'how' and 'when' to treat tricuspid regurgitation were issued. Aims Sarris-Michopoulos and colleagues carried out a meta-analysis with the aim to investigate the role of tricuspid valve repair versus tricuspid valve replacement in patients with isolated tricuspid valve regurgitation. Material and methods Outcomes of patients with first-time surgery for isolated tricuspid va…

Long-Term Results After Repair of Type A Acute Aortic Dissection According to False Lumen Patency

2009

Background Late survival and freedom from retreatment on the descending aorta was evaluated after ascending aortic repair for type A acute aortic dissection (TAAAD). Methods Between March 1992 and January 2006, 189 TAAAD patients (mean age, 52 ± 11; range, 17 to 83 years) were included; of these, 58 had a patent false lumen, and 49 had Marfan syndrome. The descending aorta was evaluated postoperatively with computed tomography (CT). Late outcomes were assessed by Cox regression analysis and actuarial survival and freedom from retreatment by the Kaplan-Meier method. Mean follow-up was 88 ± 44 months. Results There were 38 (20%) late deaths. At 10 years, survival was 89.8% ± 2.1% for patients…

Designing a new scoring system (QualyP Score) correlating the management of cardiopulmonary bypass to postoperative outcomes

2014

Aim: The aim of this study was to ascertain if a score, directly derived from CPB records, could correlate to major postoperative outcomes. Methods: An additive score (QualyP Score) was created from 10 parameters: peak lactate value during CPB, peak VCO2i, lowest DO2i/VCO2i, peak respiratory quotient, CPB time, cross-clamp time, lowest CPB temperature, circulatory arrest, ultrafiltration during CPB, number of packed red cells transfused intraoperatively. The PerfSCORE was calculated, as well. Multivariable logistic regression models were built to detect the independent predictors of: peak lactate >3 mmol/L during the first three postoperative days; the incidence of acute kidney injury ne…

Mitral valve annuloplasty and papillary muscle relocation oriented by 3-dimensional transesophageal echocardiography for severe functional mitral reg…

2012

Objective The study of the mitral valve apparatus and its modifications during functional mitral regurgitation (FMR) is better revealed by 3-dimensional (3D) transesophageal echocardiography (TOE). To plan mitral valve repair by annuloplasty and papillary muscle (PPM) relocation, we proposed a valve repair procedure oriented by the new main features obtained by real-time 3D TOE reconstruction of the mitral valve apparatus. Methods Since January 2008, 25 patients with severe FMR before mitral valve repair were examined. Mean coaptation depth and mean tenting area were 1.3 ± 0.2 cm and 3.2 ± 0.5 cm 2 , respectively. Intraoperative 2D and 3D TOE were performed, followed by a 3D offline reconst…

Evolution Of Moderate Chronic Ischemic Mitral Regurgitation In Patients Underwent Only Coronary Artery Surgery: Clinical And Echocardiographic Follow…

2008

Management of moderate chronic ischemic mitral valve regurgitation (oIMR) is still debated. Several authors favouring surgical treatment in combining with coronary artery bypass grafting (CABG) while others suggested conservative approach. However, evolution of moderate oIMR after only CABG is still unclear. Aim of this study was to evaluate prospectively, at rest and under exercise condition, the clinical outcomes and echocardiographic results of patients with moderate cIMR underwent onlv CABG.

Beneficial effects of C1 esterase inhibitor in ST-elevation myocardial infarction in patients who underwentsurgical reperfusion: a randomized double-…

2007

Background: The inflammatory cascade has been hypothesized to be an important mechanism of post-ischaemic myocardial reperfusion injury and several studies demonstrated that C1 esterase inhibitor (C1 -INH) is effective in post-ischaemia myocardial protection. Therefore, we aimed to investigate prospectively in a randomised double-blind study the cardioprotective effects of C1-INH in ST segment elevation myocardial infarction (STEMI) in patients who underwent emergent reperfusion with coronary artery bypass grafting (CABG). Methods: In this study, we enrolled 80 patients affected with STEMI who underwent emergent CABG. Patients were assigned in two groups (C1-INH group: receive 1000 Ul of C1…

Aortic stenosis: insights on pathogenesis and clinical implications

2016

Aortic stenosis (AS) is a common valvular heart disease in the Western populations, with an estimated overall prevalence of 3% in adults over 75 years. To understand its patho-biological processes represents a priority. In elderly patients, AS usually involves trileaflet valves and is referred to as degenerative calcific processes. Scientific evidence suggests the involvement of an active "atherosclerosis-like" pathogenesis in the initiation phase of degenerative AS. To the contrary, the progression could be driven by different forces (such as mechanical stress, genetic factors and interaction between inflammation and calcification). The improved understanding presents potentially new thera…

What Is the Role of Minimally Invasive Mitral Valve Surgery in High-Risk Patients? A Meta-Analysis of Observational Studies

2016

Background. Minimally invasive valve surgery is related to certain better postoperative outcomes. We aimed to assess the role of minimally invasive mitral valve surgery in high-risk patients. Methods. A systematic literature review identified eight studies of which seven fulfilled criteria for metaanalysis. Outcomes for a total of 1,254 patients (731 were conventional standard sternotomy and 523 were minimally invasive mitral valve surgery) were submitted to meta-analysis using random effects modeling. Heterogeneity and subgroup analysis with quality scoring were assessed. The primary end point was early mortality. Secondary end points were intraoperative and postoperative outcomes and long…

Is the Mean Blood Leukocyte Telomere Length a Predictor for Sporadic Thoracic Aortic Aneurysm? Data from a Preliminary Study

2012

Telomeres have been postulated as a universal clock that shortens in parallel with cellular aging. They are specialized DNA-protein structures at the ends of chromosome with remarkable functions--preventing their recognition as double-stranded DNA breaks, protecting their recombination and degradation, and avoiding a DNA damage cellular response. Telomere shortening is currently considered the best aging marker, but is also a predictor for age-related diseases, including cardiovascular diseases. Biological age clearly seems to be a better predictor of vascular risk rather than chronological age. This concept is supported by key assumptions that peripheral blood leukocyte telomere content ac…

Bifocal stimulation in patient with congenitally corrected transposition of great vessels

2012

Congenitally corrected transposition of the great vessels (CCTGV) is a rare congenital heart defect associated with multiple cardiac morphological abnormalities and conduction defects. Complete atrioventricular (AV) block occurs in 30% of patients and it may be present at birth or develop later with a rate of 2% per year; moreover, a systemic right ventricle is frequently characterized by heart failure in adult life. We used a bifocal cardiac stimulation for a young woman affected by CCTGV and atrioventricular Mobitz 2 and 2:1 block, considering structural, anatomic condition, and the high rate of pacing she underwent

Non-sutureless minimally invasive aortic valve replacement: mini-sternotomy versus mini-thoracotomy: a series of 1130 patients

2016

Objectives Aortic valve replacement through conventional sternotomy still represents the gold-standard surgical approach for aortic valve disease. However, given the increasing number of patients with comorbidities, strategies that can improve operative results are always sought. Minimally invasive aortic valve surgery, although related to a steep learning curve, might be associated with improved postoperative outcomes. The main aim of this study was to assess whether significant differences exist in terms of operative and early results between a mini-sternotomy and a right mini-thoracotomy approach for isolated aortic valve replacement without sutureless technologies. Methods This is an ob…
