Endocardial Cushion Defect
Endocardial cushion defects occur in approximately 0.19–0.56 per 1,000 live births and represents 2%–7% of congenital heart defects. The complete form of endocardial cushion defect consists of a large defect involving the inferior portion of the atrial septum and the posterior portion of the ventricular septum (red arrows). There is one common atrioventricular valve instead of two separate valves. An endocardial cushion defect can be accurately diagnosed by using only the four-chamber view.
