Case Discussion
"Snowman" or "Figure of 8" appearance is sign seen on chest x-rays in the supracardiac type of TAPVC. The patient has developed pulmonary hypertension (Eisenmenger’s physiology) as a result of the right to left shunt existing for many years, this is evidenced by the dilated central pulmonary arteries.
