Echocardiography was used to study left ventricular size and contraction in 90 patients with isolated mitral valve disease 47 patients with mitral stenosis, 26 with mixed mitral valve disease and 89 with mitral regurgitation. Left ventricular measurements included the end-diastolic internal dimension (LVIDd), mural thickness (PWTd), an index of circumferential myocardial contraction fractional ...
Indices have been developed that provide an improved means for evaluation of the degrees of severity of mitral stenosis and regurgitation. The severity of anatomic mitral valve disease found at surgery or autopsy was considered to be the determinant of the state of the valve. An index of the time for the diastolic atrioventricular pressure gradient to fall to half its value multiplied by 100 an...
A 21-year-old woman was admitted to our unit with suspected infective endocarditis. Transthoracic and transoesophageal echocardiogram demonstrated vegetation in a parachute-like asymmetrical mitral valve with severe mitral regurgitation. She was completely asymptomatic before this presentation. Though there was no evidence of mitral stenosis, this deformity is associated with transvalvular turb...
Congenital supravalvular mitral stenosis is a rare malformation characterized by the presence of a shelf-like fibrous membrane, with 1 or 2 small orifices, covering and obstructing the mitral valve. The membrane is positioned closely to the mitral valve (and sometimes it is attached to it); therefore, a preoperative diagnosis is inevitably difficult, even with the use of biplane echocardiograph...
Pulmonary hypertension frequently complicates mitral stenosis. Increased pulmonary artery pressure results from raised left atrial pressure, pulmonary arteriolar constriction, and obliterative changes in the pulmonary vascular bed, and usually responds to surgical relief of mitral stenosis. However, severe pulmonary hypertension may persist after surgical treatment of mitral stenosis. We descri...

The value of pulsed Doppler echocardiography in the assessment of mitral stenosis was studied in a consecutive series of 175 patients before rightand left-heart catheterization. All Doppler recordings were interpreted independently by two observers. Twenty patients had repeat studies to demonstrate the reproducibility of the method. Adequate recordings were obtained in 156 patients. A normal fl...

Many patients with severe aortic stenosis never undergo surgical treatment for various reasons. Apart from the standard risks, some patients face an additional problem: their carrying of a mechanical mitral valve. In these patients, transcatheter aortic valve implantation is a therapeutic option. The literature contains only few reports of this procedure being performed (usually transapically) ...
OBJECTIVE To compare Doppler, echocardiographic, and clinical variables in female and male patients with mitral stenosis. DESIGN Observational study in consecutive patients with mitral stenosis of cross sectional and Doppler echocardiographic and clinical variables and a retrospective search for a history of systemic embolism. SETTING A medical centre with 3000 beds, serving both urban and ...
