Echo-phonocardiographic evaluation of obstruction of prosthetic mitral valve.
Echo-phonocardiograms of 64 patients with multiple types of prosthetic mitral valves (PMV) were evaluated. Six patients demonstrated findings suggesting valve obstruction: four had surgical confirmation of prosthetic obstruction, one reduced cardiac output and pulmonary hypertension but no prosthetic dysfunction at surgery, and one is asymptomatic. Three of four patients with confirmed obstruct...
متن کاملThrombosed prosthetic mitral valve.
1 of 2 DESCRIPTION A 29-year-old woman presented with pulmonary oedema and low cardiac output. Her mitral valve was replaced 20 years back with a Sorin mechanical valve. She had stopped anticoagulants a month back on her own for excessive menstrual bleeding. Echo showed a gradient of 26 mm Hg across the valve with regurgitation. Fluroscopy confi rmed limited disc opening of only 15° with incomp...
متن کاملDiagnosis of prosthetic mitral valve malfunction with combined echo-phonocardiography.
Fifty-three patients were studied with combined echo-phonocardiography or phonocardiography alone following prosthetic valve replacement. In sixteen of these patients, clinical deterioration developed, and all subsequently underwent cardiac catheterization and/or surgery. Two patients came to autopsy. Included in this group of sixteen patients were five with obstructed prosthesis, six with para...
متن کاملSuccessful Use of Two Thrombolytic Drugs in Prosthetic Mitral and Aortic Valve Thrombosis
Introduction: Prosthetic valve thrombosis is a rare and severe complication of valve replacement, most often encountered with a mechanical prosthesis. The significant morbidity and mortality associated with this condition warrant rapid diagnostic evaluation. Although surgery is the first-line therapy in symptomatic obstructive mechanical valve thrombosis, thrombolytic therapy has been used as a...
متن کاملThe assessment of mitral stenosis and prosthetic mitral valve obstruction, using the posterior aortic wall echocardiogram.
The echocardiographic motion of the aortic root reflects, in part, left atrial filling and emptying. Patients with mitral valve obstruction were studied to determine whether clinically important alterations in patterns of left atrial emptying would alter motion of the posterior aortic wall. Patients with mitral stenosis had a characteristic pattern of slowing of left atrial emptying in early di...
