How does one differentiate between anomalous pulmonary venous return & transposition of great vessels?

TAPVR vs. TGA: The diagnosis of anomalous venous return (TAPVR) vs. transposition of the great vessels (TGA) is made in the newborn period. Simply put, the TAPVR baby usual presents 'pink' (no blueness) while the TGA baby will appear 'blue'. There are several variations of both TAPVR and TGA. The diagnosis can be accurately diagnosed by transthoracic ECHO and all are surgically operable with excellent results.
