Bilateral Pulmonary Artery Banding in Ebstein's Anomaly With Circular Shunting.

We present a case of critical Ebstein's anomaly with circular shunting, diagnosed in utero. The fetal cardiothoracic area ratio was elevated; tricuspid regurgitation and pulmonary regurgitation worsened with fetal hydrops. At 35 weeks 6 days of gestation, elective caesarean section delivery was performed. Planned bilateral pulmonary artery banding and pulmonary trunk ligation were performed as a palliative operation 4 hours after birth, with the infant in a stable condition. At age 5 days, we performed the Starnes operation. The postoperative course was uneventful and a bidirectional Glenn operation was performed at age 4 months.
