Overview
Tricuspid atresia is a form of congenital heart disease whereby the following defects are seen: complete absence of the tricuspid valve, absence of right atrioventricular connection, hypoplastic or an absence of the right ventricle. For survival of the infant a right-to-left atrial shunt is necessary. Repair of this lesion occurs in the first week of life and involves surgical palliation usually in three stages.
Other associated lesions are-
- Ventricular septal defect,
- Pulmonary stenosis
- Transposition of the great arteries.
