Cardiovascular examination and murmur assessment — branching viva

A four-year-old boy is referred with a soft vibratory systolic murmur at the lower left sternal edge, found at a routine check in a thriving asymptomatic child. The examiner asks: is this murmur innocent or pathological, describe your systematic cardiovascular examination, name the five auscultation areas and the two measurements that must never be omitted, and what is your disposition — then branches to a five-day-old cyanotic infant with weak femoral pulses and an arm-to-leg blood pressure gap, and asks you to name the lesion, give the resuscitation drug and its dose and adverse effects, before closing on a six-month-old who suddenly squats and turns deeply cyanotic, asking for the mechanism and the spell bundle.
