D-Shaped Left Ventricle, Anatomic, and Physiologic Implications

Figure 1

Transthoracic echocardiogram 2D during end-diastolic phase, illustrating flattening of the interventricular septum (D-shaped left ventricle) secondary to right ventricle (RV) overload and increased pressure. Important left deviation of septum into the left ventricle (LV) noted (red arrow).
