UNIVENTRICULAR REPAIR - EARLY AND MIDTERM RESULTS

A total of 202 patients (62 with tricuspid atresia and 140 without tri cuspid atresia) underwent univentricular repair at our unit from Janua ry 1990 to September 1994, Of these patients, 182 had nonfenestrated a nd 20 had fenestrated interatrial baffles, Early mortality was 15.9% ( 29/182) in the group with nonfenestrated baffles and 5% (1/20) in the group with fenestrated baffles, The follow-up period ranged from 2 to 58 months, Seven late deaths occurred, and five patients were lost to follow-up, Of 160 patients who have been evaluated in the outpatient d epartment in the past 3 months, 142 (88.75%) required no cardiac medic ines and were in functional class I, Risk factors analyzed for early m ortality and significant effusion were age, preoperative diagnosis, ty pe of Fontan modification, cardiopulmonary bypass time, aortic crosscl amp time, pulmonary artery size, associated pulmonary arterioplasty, t akedown of systemic-pulmonary artery shunt, and pulmonary artery deban ding, along with the Fontan operation, Bypass time exceeding 120 minut es was associated with a higher early mortality (12/47 vs 18/155; p = 0.0187), Bypass time exceeding 120 minutes (p = 0.0456) and aortic cro ssclamp time exceeding 60 minutes (p = 0.0278) were associated with si gnificant postoperative effusion, Other factors were not associated wi th any significantly increased risk for early mortality or postoperati ve effusions. Fenestration of the interatrial baffle appeared to decre ase early mortality, although the numbers are too small to be statisti cally significant, The prevalence of effusions did not differ signific antly between the group with fenestrated baffles and the group without fenestrated baffles.
