Background: Measurements of mitral valve area (MVA) are essential to determine the severity of mitral stenosis (MS) and adopt the best management strategies. The aim of the present study was to compare MVA determined by two-dimensional (2D) planimetry to MVA measured by continuity equation (CE) in patients with moderate to severe MS. Methods: We evaluated 73 consecutive patients with the diagno...
The speed of closure of the mitral valve during diastole, as recorded by ultrasonocardiography, is reduced in patients with mitral stenosis. A pattern of movement similar to that of severe mitral stenosis is seen in recordingsfrom patients with normally functioning mitral Starr-Edwards prostheses. Simultaneous ultrasound recordings of ball and cage movements show that the prosthetic valve remai...

BACKGROUND Aortic valve stenosis (with or without aortic regurgitation and without associated mitral stenosis) in adults in the Western world has been considered in recent years to most commonly be the result of degenerative or atherosclerotic disease. METHODS AND RESULTS We examined operatively excised, stenotic aortic valves from 932 patients aged 26 to 91 years (mean+/-SD, 70+/-12), and no...
CONGENITAL stenotic lesions of the mitral valve may be classified into various groups depending on the functional capacity of the left ventricle. In the extreme form, s8vere stenosis or atresia of the mitral valve is associated with hypoplasia of the left ventricle and aorta. Septal defects are usually present and these combinations are lethal in infaincy.i' 2 In the presence of a functioning l...

BACKGROUND Mitral stenosis, one of the grave consequences of rheumatic heart disease, was generally considered to take decades to evolve. However, several studies from the developing countries have shown that mitral stenosis follows a different course from that seen in the developed countries. This study reports the prevalence, severity and common complications of mitral stenosis in the first a...
Ultrasonic echocardiograms from the anterior cusp of the mitral valve have been obtained in 75 patients with aortic regurgitation in whom there was haemodynamic or surgical confirmation, or both, of the state of the mitral valve. Coincident mitral stenosis could be recognized from the echocardiogram in all cases by a slow diastolic closure rate and widening of the echo from the anterior mitral ...
T he hammock mitral valve is a rare congenital abnormality resulting in mitral stenosis, mitral regurgitation, or both. Although sometimes technically challenging, the repair of such lesion is possible and should be preferred to mitral valve replacement. We describe here for the first time the case of an adult patient who underwent mitral valve repair for severe mitral regurgitation related to ...
OBJECTIVES Although mitral valve repair is rarely required in neonates, this population is considered to be at high risk for adverse outcomes. The aim of this study was to review the indications for surgery, mechanisms, repair techniques, and mid-term outcomes of neonatal mitral valve repair. METHODS The demographic, procedural, and outcome data were obtained for all neonates who underwent mi...
