Accessory mitral valve as a potential source of cardioembolism.
An accessory mitral valve (AMV) is considered to arise from abnormal development of endocardial cushion tissue. It is a very rare entity, commonly diagnosed in childhood and associated with symptomatic left ventricular outflow tract (LVOT) obstruction. Here we describe the presence of AMV in a 58-year old patient who presented with a transient ischemic attack. Transesophageal echocardiography visualized a spherical structure attached to the ventricular aspect of the anterior mitral valve leaflet.
