The rupture of the anterolateral papillary muscle is less common than the posteromedial papillary muscle, as the anterolateral muscle has dual blood supply, whereas the posteromedial papillary muscle has a single blood supply. We present a a 49 years old male patient who has presented with chest pain and dyspnoea. A transesophageal echocardiogram was performed which showed that the mitral valve was normal in thickness with a flail anterior leaflet not coapting with the posterior leaflet due to the coronary artery disease. The patient underwent a mitral valve replacement and left anterior coronary artery and obtuse marginal bypass grafting.
