Comparison of the Outcome of Porcine Bioprosthetic Versus Mechanical Prosthetic Replacement of the Tricuspid Valve in the Ebstein Anomaly

Our objective was to determine the relative merits of using a bioprosthetic porcine valve (BPV) versus a mechanical valve (MechV) when tricuspid valve (TV) replacement is required in patients with Ebstein anomaly. From 1972 to 2006, 333 patients received a BPV and 45 received a MechV. Patient records were reviewed, vital status ascertained, and all patients not known to be deceased were mailed a medical questionnaire or contacted by telephone....
