==Answer==<br />
Answer c. Ebstein’s anomaly results in significant tricuspid regurgitation and<br />
enlargement of the right atrium. The condition results from an abnormally<br />
located tricuspid valve, and is associated with a PFO or ASD in 50% of cases.<br />
Cyanosis results from this right-to-left shunt. TGA without adequate mixing at<br />
arterial, atrial or ventricular level will need an emergent balloon atrial<br />
septostomy. Truncus arteriosus and Tetralogy of Fallot do not require an atrial<br />
septostomy. In severe PHT, elevated RA pressure can be palliated via<br />
decompression with an atrial septostomy.<br />
