[A case of discrete type of subpulmonary stenosis].

We reported a 8-year-old girl having discrete type of subpulmonary stenosis. This patient was associated with atrial septal defect (ASD), valvular pulmonary stenosis, and persistent left superior vena cava (PLSVC). The incidence of this type of subpulmonary stenosis is less frequent than that of subaortic lesion. ASD was closed by the autologous pericardium and a transannular patch was used for enlargement of the right ventricular outflow tract followed by commissurotomy of the pulmonary valve and resection of subpulmonary discrete lesion. She was uneventful and postoperative pulsed doppler echocardiogram showed good results.
