Systolic ejection murmur in the left sternal border consistent with pulmonic stenosis (as seen in Tetralogy of Fallot) and history of becoming cyanotic while crying also consistent with Tetralogy of Fallot
Key idea: Causes of early cyanosis from primary heart defects can be remembered with mnemonic 1, 2, 3, 4 and 5 because it can be caused by (1) persistent truncus arteriosus (1 vessel) (2) transposition of the great vessels (2 switched vessels) (3) Tricuspid atresia (Tri = 3) (4) Tetralogy of Fallot (Tetra = 4) (5) Total anomalous pulmonary venous return (5 letters in name)
Key idea: Early cyanosis does NOT mean that patient needs to have cyanosis at birth
