The porcine valve type predicts obstructive thrombosis beyond the first three postoperative months in bioprostheses in the aortic position

摘要

Background: Obstructive thrombosis of bioprosthetic valves is considered rare but may have dramatic consequences for the individual patient including repeat valve replacement, thrombolysis, or long-term anticoagulation. Whether the risk of obstructive thrombosis is dependent on the type of bioprosthesis (porcine versus bovine pericardial) is uncertain.
