Isolated anterior mitral cleft. Two dimensional echocardiographic assessment and differentiation from "clefts" associated with atrioventricular septal defect.
Five patients with isolated clefts in the anterior leaflet of the mitral valve, unassociated with atrioventricular septal defects, are described. All had significant mitral regurgitation, with the cleft being the only abnormality in three. Two patients had an associated ventricular septal defect, one with a straddling right atrioventricular valve. Angiocardiography in four showed moderate regur...
متن کاملDoppler echocardiography. The localization of cardiac murmurs.
SUMMARY A range-gated pulsed Doppler flowmeter has recently been developed that measures the average velocity of blood flow within a small tear-drop shaped (4 mm by 2 mm) sample volume. Unlike the continuous wave Doppler, the distance from the transducer face to the sampling site can be continuously varied by a range adjustment knob. Twenty patients with cardiac murmurs were evaluated in a noni...

متن کاملBioprosthetic Mitral Valve Regurgitation
The usefulness of two-dimensional color-Doppler flow-imaging (2D Doppler) in the detection, localization, and quantitation of bioprosthetic mitral valve regurgitation is uncertain. Mitral bioprostheses, before and after the creation of transvalvular (n = 33), paravalvular (n = 17), or combined (n = 23) defects, were mounted in a pulsed duplication system (flow rates, 2.5-6.5 1/min; pulse rate, ...
