Mitral Regurgitation and Prognosis After Non-ST-Segment Elevation Myocardial Infarction in Very Old Patients.

2019

Background/Objetctives: Mitral regurgitation (MR)after an acute coronary syndrome is associated with a poor prognosis. However,the prognostic impact of MR in elderly patients with non-ST-segment elevation myocardialinfarction (NSTEMI) has not been well addressed. Design: Prospective registry. Setting And Participants: The multicenter LONGEVO-SCA prospective registry included 532 unselected NSTEMI patients aged ≥80 years. Measurements: MR was quantified using echocardiography during admission in 497 patients. They were classified in two groups: significant (moderate or severe) or not significant MR (absent or mild). We evaluated the impact of MR status on mortality or readmission at 6 months…

Left atrial thrombi despite anticoagulant and antiplatelet therapy

1994

To investigate risk factors for embolization in patients with echocardiographically detected left atrial thrombi and to evaluate thrombus development, we examined 29 patients with transesophageal and transthoracic echocardiography at two points during a follow-up of 18 months. We compared patients with a history of possible arterial embolization (n = 13) with those without (n = 16) in regard to age, gender, left atrial dilatation, localization of the thrombus in the left atrial cavity, spontaneous echo contrast, and atrial fibrillation. Eight patients were treated with aspirin, 20 with phenprocoumon. Only left atrial spontaneous contrast was associated with thromboembolism (10/15 patients w…

Transcatheter Mitral Valve Repair: Single Stage Combo Approach

2019

Interplay of cardiac remodelling and myocardial stiffness in hypertensive heart disease: a shear wave imaging study using high-frame rate echocardiog…

2019

Abstract Aims To determine myocardial stiffness by means of measuring the velocity of naturally occurring myocardial shear waves (SWs) at mitral valve closure (MVC) and investigate their changes with myocardial remodelling in patients with hypertensive heart disease. Methods and results Thirty-three treated arterial hypertension (HT) patients with hypertrophic left ventricular (LV) remodelling (59 ± 14 years, 55% male) and 26 aged matched healthy controls (55±15 years, 77% male) were included. HT patients were further divided into a concentric remodelling (HT1) group (13 patients) and a concentric hypertrophy (HT2) group (20 patients). LV parasternal long-axis views were acquired with an ex…

Functional Mitral Regurgitation Predicts Short-Term Adverse Events in Patients With Acute Heart Failure and Reduced Left Ventricular Ejection Fraction

2017

Functional mitral regurgitation (FMR) is a common finding in patients with acute heart failure (AHF) and reduced left ventricular ejection fraction (heart failure and reduced ejection fraction [HFrEF]). However, its clinical impact remains unclear. We aimed to evaluate the association between the severity of FMR after clinical stabilization and short-term adverse outcomes after a hospitalization for AHF. We prospectively included 938 consecutive patients with HFrEF discharged after a hospitalization for AHF, after excluding those with organic valve disease, congenital heart disease, or aortic valve disease. FMR was assessed semiquantitatively by color Doppler analysis of the regurgitant jet…

Effect of antibiotic treatment on vegetation size and complication rate in infective endocarditis

1997

Background: Infective endocarditis is associated with significant morbidity and mortality, with valvular destruction, and with congestive heart failure. Embolic events are more common in patients with echocardiographically discernible vegetations, especially when vegetations are >10 mm in diameter. Hypothesis: The objective of the study was to follow vegetation morphology during native valve endocarditis, to compare it with the clinical course and antibiotic treatment chosen, and to evaluate whether the impact on vegetation size and complication rate of antibiotic regimens differed in patients with positive and negative blood cultures. Methods: The effect of different antibiotic regimes on …

Acute Kidney Injury After Percutaneous Edge-to-Edge Mitral Repair.

2020

BACKGROUND In catheter-based procedures, acute kidney injury (AKI) is a frequent, serious complication ranging from 10% to 30%. In MitraClip (Abbott Vascular, Santa Clara, California), a usually contrast-free procedure, there is scarce data about its real incidence and impact. OBJECTIVES This study aimed to evaluate incidence, predictive factors, and midterm outcomes of AKI in patients with significant mitral regurgitation (MR) undergoing transcatheter valve repair with MitraClip. METHODS A total of 721 patients undergoing MitraClip were included. AKI was defined as an absolute or a relative increase in serum creatinine of >0.3 mg/dl or >= 50%, respectively, or the need for hemodialysis dur…

Immediate effect of the MitraClip procedure on mitral ring geometry in primary and secondary mitral regurgitation.

2013

Percutaneous treatment of mitral regurgitation (MR) has been shown to reduce MR severity and improve functional outcomes. Surgical treatment of MR usually includes mitral annulus reduction. The influence of the MitraClip w on annulus geometry is not clear. We wanted to investigate whether the procedure itself reduces annulus diameter and if there may be differences between secondary or functional (SMR) and primary (PMR) MR. Methods and results We retrospectively assessed 3D echocardiography (3D-TEE) data of 55 patients acquired during the procedure shortly before and after clip placement for changes in annulus diameter and area. Measurements were done with QLAB software. Patients were categ…

A strange pneumonia

2013

We report the case of a 62-year-old man with non-ST elevation myocardial infarction complicated by partial rupture of the antero-lateral papillary muscle in which severe mitral regurgitation with lateralized direction towards the right pulmonary veins gave unilateral pulmonary oedema, resembling an acute pneumonia.Unilateral pulmonary oedema is a rare entity, more frequently appearing as opacity of the right lung and always associated with severe mitral regurgitation. It is very important to suspect and promptly recognize unilateral pulmonary oedema because initial misdiagnosis leads to a delay in the initiation of appropriate treatment and to an increased risk of mortality.

ECHOCARDIOGRAPHIC ASSESSMENT OF 537 DOGS WITH MITRAL VALVE PROLAPSE AND LEAFLET INVOLVEMENT

2009

In this work we investigated which mitral valve leaflet was most often involved in mitral valve prolapse with degenerative mitral valve disease and whether there was an association with breed, age, gender, or weight. Five hundred and thirty-seven dogs with mitral valve prolapse-degenerative mitral valve disease were assessed; the cross-breed dog was the most represented breed (248 dogs, 46.2%). Mitral valve prolapse was more common in male dogs, and the average age was 11.3 +/- 2.8 years. Prolapse of the anterior leaflet was present in 48.4% of dogs, prolapse of the the posterior leaflet in 7.1%, and bileaflet prolapse was present in 44.5%; this distribution is different than that typically…
