title: Severe aortic and mitral calcification in identical twin boys.
abstract: Identical twin boys presented with exercise-induced syncope. Echocardiographic examination revealed severe calcification at aortic valves, mitral anterior leaflets, and mitral annuli in both patients. In addition, basal interventricular septum was also involved in 1 patient. Doppler evaluation demonstrated severe aortic stenosis with a peak gradient of 112 and 118 mm Hg in both patients. Moderate mitral stenosis was also detected in one of them. Patients underwent operation for valve replacement.
