Abstract:
Objective To describe the echocardiographic and clinical findings of patients with accessory mitral valve(AMV).Methods Four adult patients were diagnosed to have AMV by Doppler echocardiography.Results All the four patients had cardiac murmur but 2 were asymptomatic.Echocardiogram showed that two cases had isolated AMV with significant left ventricular outflow tract (LVOT)obstruction.Another patient was complicated by idiopathic hypertrophic subaortic stenosis and his systolic pressure gradient across the LVOT reduced to normal after taking negative inotropic drugs.The fourth patient was associated with complex congenital cardiac anomalies but without LVOT obstruction.Conclusions AMV may not be very rare as previously reported.An echocardiographic examination Can detect AMV and difierentiate it from other causes of LVOT obstruction.
