Doppler echocardiogram of atrioventricular (AV) canal defect with AV valve regurgitation
Doppler echocardiogram of atrioventricular (AV) canal defect with AV valve regurgitation
Two-dimensional color-flow Doppler four-chamber image across common AV valve in systole in a patient with an AV canal defect. In the right panel, color Doppler image demonstrates right AV valve regurgitation (asterisk), left AV valve regurgitation (double asterisk) and left-to-right shunting (arrow).
RV: right ventricle; LV: left ventricle; RA: right atrium; LA: left atrium; R: right; S: superior.
