Abstract:
Hemolytic anemia is a well-recognized complication in patients with left-sided mechanical heart valves. It is rare to see hemolysis with a bioprosthetic valve in the right ventricular outflow tract. We report a 4-year-old-girl with history of truncus arteriosus status-post repair who developed hemolytic anemia as a result of a calcified and obstructed bioprosthetic right ventricular to pulmonary artery-valved conduit. The hemolysis was alleviated by replacing the obstructed conduit with a larger valved conduit.
