Tricuspid valve closure for neonatal Ebstein's anomaly.

A respirator-dependent 11-day-old boy with Ebstein's anomaly is presented. His cardiac anomaly with progressive cardiomegaly was first noticed at 24 weeks' gestation on fetal echocardiography. After birth, he required mechanical ventilation because of massive tricuspid regurgitation and restricted pulmonary blood flow. The operation of tricuspid valve patch closure, resection of right atrial wall, and central shunt successfully weaned him from the respirator on postoperative day 13. Cavopulmonary anastomosis was performed without problem when the patient was 8 months of age.
