Subxiphoid two-dimensional echocardiographic detection of tricuspid valve prolapse

A patient with click and late systolic murmur syndrome originating in the right side of the heart is described. Prolapse of the anterior tricuspid leaflet was demonstrated by subxiphoid two-dimensional echocardiography alone. Neither of the mitral leaflets showed any evidence of prolapse on the echocardiogram. The prolapsed anterior tricuspid leaflet and mild regurgitation were confirmed by right heart cineangiogram.
