BACKGROUND Valvular heart diseases and mainly rheumatic heart diseases complicate about 1% of pregnancies. During pregnancy physiological hemodynamic changes of the circulation are the main cause of mitral stenosis (MS) decompensation. Prior to introduction of percutaneous mitral balloon commissuroplasty (PTMC), surgical comissurotomy was the preferred method of treatment in patients with refra...

We present new algorithms to compute patient specific strain maps for mitral valve leaflets, by tracking and modeling deformations of the mitral valve apparatus in 3D echocardiography. We can then quantify comparisons of mitral leaflets strain maps between normal patients and cases of mitral valve prolapse or regurgitation. For patients with mitral valve regurgitation, we compare mitral leaflet...

Double orifice mitral valve (DOMV) is an uncommon congenital heart defect. The isolated occurrence of this anomaly is very rare and, more often, is associated with another congenital malformation, dominated by atrioventricular canal defects (AVCD). Mitral insufficiency and/or stenosis may complicate this malformation. Treatment may be summarized as abstention, surgical valve repair, or valve re...

Background: Mitral valve disease is the most common acquired heart disease in dogs. Mitral valve regurgitation (MR) due to endocardiosis is an important cause of morbidity and mortality in dog. Echocardiography as a non-invasive tool is routinely used to evaluate and diagnose different disorders in the heart. Objectives: The purpose of this study is to determine the efficacy of medical treatmen...

results of the 41 patients with dcm, echocardiography examination revealed 11 patients (27%) without mitral regurgitation and 12 (29%) with mild, 11 (27%) with moderate, and seven (17%) with severe mitral regurgitation. all of the morphological and functional parameters of left ventricle, atrium and mitral valve in dcm patients were greater than those in healthy subjects (all p < 0.05), except ...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2014203592 DESCRIPTION A 56-year-old man had undergone mitral valvuloplasty owing to a 3-year history of mitral insufficiency caused by chordae tendineae rupture. Prosthetic valve ring and artificial chordae tendineae are usually used in this case. The patient was referred to the hosp...

Severe aortic insufficiency may accelerate mitral valve closure. We noted this echocardiographic finding in several patients with the acute onset of severe aortic insufficiency. Accordingly, we examined our total echocardiographic series retrospectively for early closure of the mitral valve (ECMV) in the setting of aortic insufficiency and found it in 11 of 53 patients with confirmed aortic ins...

Double orifice left atrioventricular valve (DOLAVV) or double orifice mitral valve (DOMV) is a rare congenital cardiac anomaly manifesting either as an isolated lesion (mitral stenosis or mitral insufficiency) or in association with other congenital cardiac defects. Signs of mitral valve disease are usually present along with the symptoms of associated coexistent congenital heart diseases. Mitr...

BACKGROUND We performed a prospective, randomized trial comparing percutaneous balloon commissurotomy with surgical closed commissurotomy in 40 patients with severe rheumatic mitral stenosis. METHODS AND RESULTS Data were analyzed by investigators who were masked to treatment assignment or phase of study. Patients randomized to balloon (n = 20) or surgical (n = 20) commissurotomy had severe m...

The complex anatomy of mitral valve demands precise and sophisticated imaging during any intervention .Transesophageal echocardiography has been the most frequently used modality. With the advent of three-dimensional echocardiography a more comprehensive description of the mitral valve is now possible. This review aims to discuss the framework for imaging the mitral valve by three-dimensional e...
