Unicuspid aortic valve is a rare congenital malformation that usually presents in the 3rd to 5th decade of life—and usually with severe aortic stenosis or regurgitation. It often requires surgical correction. Diagnosis can be made with 2- or 3-dimensional transthoracic or transesophageal echocardiography, cardiac computed tomography, or cardiac magnetic resonance imaging. We report the case of a 31-year-old man who presented with dyspnea on exertion due to severe aortic stenosis secondary to a unicuspid unicommissural aortic valve. After aortic valve replacement, this patient experienced complete heart block that required the placement of a permanent pacemaker.
