Traumatic left ventricular false aneurysm with significant regurgitation from left ventricular outflow tract to left atrium: delineation by two-dimensional and color flow Doppler echocardiography.

A 22-year-old man was asymptomatic 23 months after an automobile accident but had clinical evidence of progressive mitral insufficiency. Two-dimensional and color flow Doppler echocardiography demonstrated a false aneurysm adjacent to the left ventricular outflow tract and significant regurgitation of blood through a traumatic channel from the left ventricular outflow tract to the left atrium. The patient underwent successful surgical closure of the false aneurysm and repair of the traumatic left atrial regurgitation.
