Echocardiogram of double-chambered right ventricle

Transthoracic echocardiogram with two-dimensional parasternal short-axis view (left) and color flow Doppler (right) at the level of the aortic valve, demonstrating flow acceleration with systolic obstruction in the right ventricle (arrow) typical of double-chambered right ventricle. The muscular ridge divides the right ventricle into two chambers, one proximal to the obstruction and one distal to the obstruction. Mild central aortic regurgitation as well as mild tricuspid regurgitation are also identified by echo-Doppler.
