title: Multiple left-sided cardiac lesions in one of Noonan's original patients.
abstract: We describe a complex case of obstruction of the left ventricular outflow tract in one of Dr. Noonan's original patients. Intraoperative findings revealed pathology at the valvar, subvalvar and supravalvar positions. Patients with Noonan syndrome are traditionally described as having right-sided cardiac pathology. Review of the literature revealed left-sided lesions to occur in a substantial number of these patients. We therefore suggest the routine employment of cardiac ultrasonography in all patients with Noonan syndrome with attention directed toward left-sided pathology, as well as the frequent pulmonary valvar pathology.
