Abstract:
Valve-in-valve transcatheter aortic valve replacement (ViV-TAVR) has been popularized as an attractive alternative to redo surgical aortic valve replacement for bioprosthetic valve dysfunction. Acute valve thrombosis has been occasionally described after ViV-TAVR. Lack of anticoagulant therapy has been always considered a crucial risk factor. This report describes a rare case of early postoperative fatal ViV-TAVR thrombosis despite adequate anticoagulation in addition to dual antiplatelet therapy.
