Abstract

Noonan syndrome is characterized by typical facies, congenital heart defect, and some clinical features similar to Turner syndrome, but with normal chromosomes. The most commonly associated cardiac defects are pulmonary valvular stenosis and strial septal defect. We experienced a case of Nonan syndrome associated with pulmonay valve stenosis with double-chambered right ventricle and atrial septal defect and cryptorchidism. Pulmonary valvotomy was done through transannular incision. Hypertrophied muscle bundles were excised. Atrial septal defect was closed directly. RVOT was reconstructed with pericardial transannular patch. Orchiopexy was performed simultaneously without any problem.
