Ventricular Septal Defect

Tricuspid atresia is a congenital anomaly in which the tricuspid valve is absent and the right ventricle is small (hypoplastic).

A ventricular septal defect (VSD) occurs when there is direct communication between the left and right ventricles. This can be a congenital anomaly or acquired as a complication of a myocardial infarction.

Transposition of the great vessels is a congenital cardiac anomaly in which the aorta arises from the right ventricle and the pulmonary artery arises from the left ventricle.

A small ventricular septal defect is termed “maladie de Roger” or Rogers’s disease after the initial describer in 1879 Henri Louis Roger, a pediatric cardiologist known as an expert in cardiac auscultation.
