Determinants of acute events leading to mortality after shunt procedure in univentricular palliation

Abstract

Objective: The study objective was to identify determinants of adverse outcomes in patients undergoing univentricular palliation after the shunt procedure. Methods: We performed a retrospective study of patients with univentricular lesions undergoing modified Blalock–Taussig shunt and central shunt placement, with or without concomitant Norwood/Damus–Kaye–Stansel procedures, between 2004 and 2014. Results: Overall, 246 patients were included, with 150 patients undergoing concomitant Norwood/Damus–Kaye–Stansel procedure. The 30-day and in-hospital mortality were 7.3% and 14.6%, respectively. Progression to bidirectional cavopulmonary connection was achieved in 76% of patients. Acute events oc..
