The mitral valve is the most complex of the cardiac valves. Its leaflets are unequal in size:
one is continuous with the left atrial endocardium and the other with the aorta. The valve …

A brief review of the pathophysiology of aortic and mitral valve disease and the
hemodynamic results of valve replacement with caged ball prostheses are described. In …

Necropsy observations are described in 224 patients who died from 1963 through October
1972 after replacement of one or more cardiac valves by prostheses: 128 patients died …

Mitral valve replacement was carried out in 100 patients with acquired mitral valvular
disease. Preoperatively, two patients were in functional class II (NYHA), 64 in class III, and …

Paravalvular leaks were encountered in 27 of 203 patients (13 per cent) following aortic
valve replacement and in 10 of 108 patients (9 per cent) after prosthetic mitral valve …

Excerpt Although most patients who have prosthetic replacement of diseased heart valves
have significant symptomatic improvement after surgery, it has become apparent that a small …

Two patients with prosthetic mitral valves demonstrated clinical deterioration and were found
by left ventriculography to have pseudoaneurysms of the inferior left ventricular wall. Both …

Twenty-three patients who were symptomatic after mitral valve replacement, and in whom
mitral paraprosthetic regurgitation was a possible cause of deterioration, were investigated …

A retrospective analysis was made of 110 consecutive patients undergoing isolated mitral
valve replacement with a ball valve prosthesis in an attempt to define factors associated with …

Isolated absence of the opening click of the mitral disk-valve prosthesis was noted in six
patients subsequently found to have suture disruption. Of five reoperated on, four survived …
