Operative repair for tricuspid atresia.

Twelve patients with tricuspid atresia underwent physiological operative repair. The criteria for their selection for operation included normal pulmonary vascular resistance and normal left atrial and left ventricular end-diastolic pressures. Four patients died (30% mortality). The 8 surviving patients developed pleural effusion, ascites, and hepatomegaly, which markedly improved in the subsequent weeks. Five of the 8 survivors underwent cardiac catheterization. The arterial oxygen saturation in these patients averaged 82% preoperatively, 89% immediately postoperatively, and 94% or better six months later. All had improved subjectively and developed increased exercise tolerance.

Results following physiological repair for tricuspid atresia.

Fourteen patients underwent a physiological operation for tricuspid atresia. Seven patients survived up to 3 years after operation. Six patients underwent hemodynamic studies 2 to 34 months postoperatively (mean, 15 months). Average age at the time of operation was 14 years (range, 5 to 25 years). Postoperative studies showed 4 patients to be in sinus rhythm and 2 in junctional rhythm. Right atrial pressure was elevated an average of 17 mm Hg (range, 10 to 34 mm Hg). All patients showed good atrial transport function regardless of their rhythm. Two had a right atrium-left pulmonary artery gradient of 1.5 to 10 mm Hg across the conduit. Average arterial saturation was 92% (range, 87 to 97%), on improvement of 13% over preoperative values. Residual hypoexmia was due to pulmonary vein desaturation and to atrial right-to-left shunting early postoperatively and later, to atrial right-to-left shunting alone.
