RATIONALE Doppler echocardiography has been demonstrated to be accurate in diagnosing valvular lesions in rheumatic heart disease (RHD) when compared to clinical evaluation alone. OBJECTIVE To perform Doppler echocardiography in children clinically diagnosed by the Jones criteria to have acute rheumatic fever (ARF), and to then compare the effectiveness of echo in detecting single/multi-valvu...

A better understanding of the factors involved in ensuring competence of the mitral valve based on knowledge of the function of the leaflets, chordae tendineae, and papillary muscles has expanded the clinical range of systolic mitral regurgitation. For all this, diastolic mitral regurgitation remains a curiosity. Late diastolic mitral regurgitation has been described together with reversal of t...

Left ventricular cineangiography was performed in 37 patients with mitral regurgitation. Twenty-one patients had rheumatic mitral valve disease determined by careful surgical and pathologic examination, 10 had papillary muscle dysfunction, and six had chordae tendineae rupture. Fourteen of the 16 patients considered to have nonrheumatic mitral regurgitation were confirmed surgically; the other ...

Functional ischemic mitral regurgitation is a complex disorder with a poor prognosis. Although the underlying anatomical and pathophysiological mechanisms are not entirely clear, it is known that postinfarction left ventricular remodeling is the most significant factor in the development of this mitral valve lesion. Echocardiography and magnetic resonance imaging have made significant contribut...

Functional mitral regurgitation is a significant complication of end-stage cardiomyopathy. Dysfunction of one or more components of the mitral valve apparatus occurs in 39-74% and affects almost all heart failure patients. Survival is decreased in subjects with more than mild mitral regurgitation irrespective of the aetiology of heart failure. The goal of treating functional mitral regurgitatio...

BACKGROUND The typical cardiac manifestations of Marfan syndrome are aortic regurgitation with progressive dilatation of the aortic root, which may cause dissection and rupture of the ascending aorta, mitral valve prolapse and mitral valve regurgitation. In this study, we aimed to show echocardiographic findings in 11 patients with Marfan syndrome. METHODS Diagnosis of Marfan syndrome was bas...

Mitral valve repair provides substantial advantages over mitral valve replacement in patients with severe mitral regurgitation. However, because of the possibility of persistent regurgitation, an intraoperative technique is needed to provide an immediate and accurate assessment of the adequacy of the repair before closure of the chest. One hundred patients with pure mitral regurgitation were st...

Twenty-three patients who were symptomatic after mitral valve replacement, and in whom mitral paraprosthetic regurgitation was a possible cause of deterioration, were investigated by cardiac catheterization, phonocardiography, and echocardiography. Severe paraprosthetic regurgitation was present in ii patients and slight regurgitation in 2 patients. Two patients had aortic regurgitation which w...

OBJECTIVE We evaluated the outcomes of minimally invasive mitral valve surgery via a right anterior thoracotomy approach in patients with isolated severe mitral regurgitation and severely reduced left ventricular systolic function. METHODS We retrospectively reviewed all minimally invasive mitral valve surgeries for mitral regurgitation in patients with an ejection fraction of 35% or less per...
