Right atrial-right ventricular anastomosis for correction of tricuspid atresia.

Abstract

Previously reported methods for the correction of tricuspid atresia involve the use of conduits and/or valves. Since many of the younger patients will outgrow their conduits and the long-term durability of the valve prostheses is open to question, we have devised an operation in which the right atrial (RA) appendage is anastomosed to the right ventricle (RV) with the aid of a pericardial patch. The RV, if not too hypoplastic, is used as a pumping chamber and the pulmonary valve is in its normal position. Three patients, 8, 9, and 12 years of age, were operated on with good clinical and hemodynamic results. Postoperatively, all three were acyanotic and had improved physical capacity compared with their preoperative status. The RA pressure in the first two patients 1 year after operation was 12 mm. Hg and at angiocardiography the RA-RV anastomosis was widely patent. In one of the patients, the RV was too hypoplastic to function. It should be possible to perform this operation even in younger patients and it may eliminate the need for palliative procedures and reoperations.
