Aortic stenosis: A routine diagnosis with a rare cause

A 40-year-old male patient presented with dyspnea on exertion and palpitation from 2 months ago. Physical examination revealed normal vital sign and a systolic murmur grade 3/6 in aortic area. Echocardiography revealed unicuspid aortic valve with an eccentric orifice, calcification, and aortic valve area of 0.9 cm 2 .
