Abstract
Arrhythmic mitral valve prolapse syndrome is associated with a high risk of death. A 60-year-old man with arrhythmic mitral valve prolapse syndrome was monitored with an implantable loop recorder. Nine months later dyspnea developed, followed by cardiac arrest. Echocardiography showed mitral valve chordal rupture. He underwent successful surgical mitral valve repair. (Level of Difficulty: Intermediate.)

Abstract
A 69-year-old male presented to the emergency room with dyspnea on exertion lasting more than 2 weeks. Echocardiography showed an ill-defined subaortic structure. Subsequent transesophageal echocardiography revealed a parachute-like structure prolapsing into the left ventricular outflow tract causing subvalvular aortic obstruction. Surgical excision confirmed this structure as an accessory anterior mitral leaflet. (Level of Difficulty: Intermediate.).
