Abstract
Accessory mitral valve tissue is a very rare congenital cardiac malformation and it is an uncommon cause of left Ventricular outflow tract obstruction(LVOTO). The pathogenetic mechanism of subaortic obstruction is thought to be systolic ballooning of the abnormal valve tissue into LVOT. We are reporting a case of an accessory mitral valve tissue that was associated with LVOTO, and this was completely relieved after trans-aortic surgical excision of the accessory tissue.
