Autologous Ross operation for congenital aortic stenosis

Congenital aortic stenosis is a relatively common cardiac anomaly encountered in approximately 5% of all children with heart disease. The Ross procedure is increasingly used for replacement of the aortic valve in children. We report a 12-year-old boy who was born with congenital aortic stenosis secondary to a bicommissural aortic valve. The patient underwent open valvotomy in infancy and aortic valvuloplasty 2 years later. Residual/recurrent stenosis prompted referral for aortic valve replacement, and he underwent an autologous Ross procedure, in which the aortic root was replaced with a pulmonary autograft and the repaired aortic valve was used to restore right ventricular-to-pulmonary artery continuity. The postoperative course was unremarkable. Nitroprusside, esmolol, and labetolol were used to control postoperative hypertension. He was discharged 4 days after surgery on oral furosemide and aspirin, and he has had no cardiovascular symptoms during follow-up. Recent echocardiography demonstrated mild right ventricular outflow tract obstruction with a peak velocity of 3.6 m/sec, with a gradient of 42 mmHg and moderate pulmonary insufficiency. There was no left ventricular outlet tract obstruction or aortic insufficiency.
