Abstract Unicuspid aortic valve (UAV) is a rare congenital anomaly, frequently associated with early progression to severe aortic stenosis and aortopathy. We report the case of a 38-year-old woman who presented with difficult-to-control hypertension and progressive exertional dyspnea. Transthoracic echocardiography revealed critical aortic stenosis (peak gradient of 183 mmHg, mean gradient of 125 mmHg, and valve area of 0.59 cm2), associated with mild aortic regurgitation and ascending aortic dilation (45–46 mm). Three-dimensional transesophageal echocardiography confirmed a unicommissural UAV, as well […]
