Abstract

Successful open aortic valvotomy and end-to-end anastomosis were performed to the patient with critical aortic stenosis and CoA on the first day of life. A fetus was diagnosed as aortic stenosis and coarctation by fetal echocardiography at 29 weeks of gestation. The mother was transferred to our hospital at the onset of labor and delivered vaginally at 40 weeks of gestation. Soon after the birth, the newborn, birth weight 2630 gram, female, underwent echocardiography by pediatric cardiologists which demonstrated the aortic orifice of 5.1 mm in diameter and thickened cusps with poor mobility. Transaortic pressure gradient measured by Doppler echocardiography was 111 mmHg and the left ventricular wall motion was hyperdynamic without any signs of endocardial fibroelastosis. Prostaglandin E1 administration was started to maintain systemic circulation and the hemodynamic status has been stable before surgery. On her first day of life, the operation was performed using cardiopulmonary bypass with moderate hypothermia. Isolated cerebral and myocardial perfusion technique was applied during the repair of coarctation of the aorta. The open aortic valvotomy with resection of myoxomatous nodules on leaflet edges effectively released pressure gradient across the aortic valve without regurgitation. Post-operative course was uneventful and she discharged at 28th day after surgery. We conclude early diagnosis including fetal echocardiography and early repair would lead the better surgical outcome to the neonates with critical aortic stenosis.
