The murmur may also be prominent over the right cranial thorax. Abnormal subvalvular or aortic valvular anatomy may be evident. Sudden acceleration of blood flow into the left ventricular outflow tract with turbulent, high velocity systolic flow across the aortic valve and into the ascending aorta. Concurrent aortic regurgitation is usually present. [Congenital Defect]
