TOF is the only cyanotic disease out of the lot.
RV heave is prob due to RV hypertrophy. Single S2 cuz of diminished pulmonic component, systolic murmur d/t VSD
what does the systolic click signify? Pulmonic stenosis?
Infant/toddler with early cyanosis and clubbing with murmur consistent with RV hypertrophy (RV heave), Pulmonic stenosis (single S2), and a VSD (systolic murmur), which are 3/4 of the features of 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)

A classic
There are 4 murmur characteristics described and tetra logy of fallot has 4 problems (PROVe)
Single S1 from reduced pulmonic component (remember, MTAP, MT = S1, AP = S2)
