[A successful repair of ventricular septal defect and patient ductus arteriosus associated with pulmonary hypertension in an infant with left lung agenesis].

We report the first case of successful repair of ventricular septal defect (VSD) and patent ductus arteriosus (PDA) associated with pulmonary hypertension in an infant with left lung agenesis. A 70-days-old infant was referred to our hospital with the diagnosis of congenital heart disease and abnormalities of the left lung. Two-dimensional echocardiogram showed ventricular septal defect and patent ductus arteriosus associated with pulmonary hypertension. Computed tomogram of the chest and bronchogram confirmed agenesis of the left lung. The operation was performed at age 114 days with the body weight 4333 g. VSD was closed with the patch and PDA was ligated under cardiopulmonary bypass. Postoperative course was uneventful. Cardiac catheterization, 50 days after operation, revealed normal pulmonary arterial pressure and good cardiac function. Agenesis of the lung is a rare condition and often associated with congenital abnormalities of the skeletal, gastrointestinal, genitourinary and cardiovascular system. As the prognosis is poor especially in those with congenital heart disease, the cardiac surgery is mandatory for the patient to survive.
