A 29-year-old woman presented 21 weeks into her first pregnancy with an episode of pulmonary edema. Transthoracic echocardiography suggested severe mitral stenosis (A, Online Video 1) due to a parachute mitral valve with single functioning papillary muscle (B, Online Video 2). Transesophageal echocardiography confirmed that the mitral valve could not be treated percutaneously but it also identified a bicuspid aortic valve without evidence of a subaortic ridge (C,Online Video 3). Cardiac magnetic resonance imaging identified the single functioning papillary muscle in a short-axis cine image (D, Online Video 4) and an aortic coarctation with a tight isthmus in the proximal descending aorta (E, Online Video 5). Complete Shone complex consists of a supravalvular mitral membrane, parachute mitral valve, subaortic stenosis, and coarctation of the aorta, but partial forms are more commonly diagnosed in adults when only 2 or 3 obstructive lesions are present.
