18F-FDG PET/CT in cardiovascular infection and inflammation.

2021

The diagnosis of cardiovascular infection and inflammation by [18F]FDG PET/CT in Nuclear Cardiology is of growing interest, because with respect to echocardiography this technique has improved the certainty in the diagnosis of infective endocarditis in patients with prosthetic valves, the increasing number of patients with implantable cardiac devices because of the progressive ageing of the population, as well as in patients with suspected large vessel vasculitis. All are serious clinical situations which require correct diagnosis and appropriate treatment as soon as possible, because they can cause severe complications, high mortality and also increased health care costs. We review the use…

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…

Three-dimensional parametric modeling of bicuspid aortopathy and comparison with computational flow predictions

2017

Bicuspid aortic valve (BAV)-associated ascending aneurysmal aortopathy (namely "bicuspid aortopathy") is a heterogeneous disease making surgeon predictions particularly challenging. Computational flow analysis can be used to evaluate the BAV-related hemodynamic disturbances, which likely lead to aneurysm enlargement and progression. However, the anatomic reconstruction process is time consuming so that predicting hemodynamic and structural evolution by computational modeling is unfeasible in routine clinical practice. The aim of the study was to design and develop a parametric program for three-dimensional (3D) representations of aneurysmal aorta and different BAV phenotypes starting from s…

TCT-34 Prediction of acute kidney injury after TAVR by new biomarkers

2017

Acute kidney injury (AKI) is a common complication after transcatheter aortic valve replacement (TAVR) and is associated with increased morbidity and mortality. Routinely used biomarkers such as creatinine show a diagnostic gap in the first hours after kidney injury. Thus, new biomarkers for earlier

The Revolution in Heart Valve Therapy: Focus on Novel Imaging Techniques in Intra-Procedural Guidance

2021

Transcatheter valvular interventions have undergone significant progress over the last years with novel treatment options in even complex valvular conditions. In conjunction with this development, ...

Prior oral conditions in patients undergoing heart valve surgery

2017

Background Patients scheduled for heart valve surgery should be free of any oral infectious disorders that might pose a risk in the postoperative period. Few studies have been made on the dental conditions of such patients prior to surgery. The present study describes the most frequent prior oral diseases in this population group. Material and Methods A prospective, observational case-control study was designed involving 60 patients (30 with heart valve disease and 30 controls, with a mean age of 71 years in both groups). A dental exploration was carried out, with calculation of the DMFT (decayed, missing and filled teeth) index and recording of the periodontal parameters (plaque index, gin…

Treatment of pulmonary hypertension in patients undergoing cardiac surgery with cardiopulmonary bypass: a randomized, prospective, double-blind study

2006

Pulmonary hypertension can already be present in patients undergoing cardiac surgery or can be exacerbated by cardiopulmonary bypass. Postoperative treatment is still a challenge for physicians. The aim of this study was to evaluate the effects of inhaled prostacyclin (iPGI2) and nitric oxide (iNO) compared with those of intravenous vasodilators.This prospective, randomized, double-blind study included 58 patients affected by severe mitral valve stenosis and pulmonary hypertension with high pulmonary vascular resistance (250 dynes x s x cm(-5)) and a mean pulmonary artery pressure25 mmHg. All patients were monitored by central venous, radial arterial and Swan-Ganz catheters. Data were recor…

Histopathologic Findings in Early Encapsulated Blebs of Young Patients Treated With the Ahmed Glaucoma Valve

2010

Objective/aim Uncontrolled glaucoma presents a challenge for the ophthalmic surgeon especially in children and juvenile patients. For many patients who have undergone failed surgical procedures before, episcleral implants remain the last choice. Encapsulated blebs forming over antiglaucoma devices present a complication leading to malfunctioning or even failure with reincrease in intraocular pressure. We report our histopathologic findings of such blebs developing around the Ahmed glaucoma valve (AGV) after a short time period in young patients. Materials and methods Nine young patients (2 to 17 y of age) with otherwise uncontrollable glaucoma were treated with AGV (models FP-7 and FP-8, si…

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…
