Overview

Echocardiography is the imaging modality of choice for tricuspid atresia. Findings include:

• Atrial septal defect (ASD)
• Ventricular septum defect (VSD)
• Patent ductus arteriosus (PDA)
• Aortic arch anomaly
• Theleft ventricle is larger than the right ventricle
• Color flow doppler is absent between theright atrium and right ventricle

Echocardiography

Shown below is an ECHO image demonstrating atresic tricuspid valve and ventricular septal defect.

Shown below is a short video of an echocardiogram of a patient with tricuspid atresia.

Shown below is a echocardiogram of a 20 day old neonate with tricuspid valve atresia. This congenital anomaly is not compatible with life unless there is a right-to-left shunt. In the case presented below, there is VSD and ASD, and it represents about 1% of all congenital anomalies.
