Video 1. Cardiac magnetic resonance imaging cine in the oblique axial plane at the aortic root shows Type B quadricuspid aortic valve with 3 equal-sized cusps and 1 smaller cusp (arrow), along with 4 sinuses. Incomplete closure of the aortic valve is also seen during diastole, causing aortic regurgitation.
Video 2. Cardiac magnetic resonance imaging cine in the oblique coronal view through the aortic valve and left ventricular outflow tract shows severe aortic regurgitation.

Video Supplement to "Quadricuspid Aortic Valve" (September 2023 Case Report).

A 56-year-old man presented with typical angina for 1 day and a prior history of exertional  dyspnea of 6 months duration. Clinically, he was diagnosed with severe aortic regurgitation (AR). Electrocardiogram showed left ventricular hypertrophy with volume overload. Transthoracic echocardiography (TTE) showed severe AR with mild left ventricular dysfunction. Although aortic valve morphology appeared to be quadricuspid, it was not clear on TTE. In view of elevated troponin levels, a coronary angiogram was done that showed 90% stenosis in the proximal left anterior descending artery.
