The most likely clinical diagnosis is:: (A) Congenital aortic stenosis, (B) Coarctation of aorta, (C) Patent ductus arteriosus, (D) Congenital aortoiliac disease
Answer is B. b. Coarctation of aorta(Ref: Nelson's 20/e p 2205, Ghai 8/e p 413-433)Feeble femoral pulsations compared to strong brachial pulsations suggests of coarctation of aorta.
