Discontinuation of anticoagulation combined with initiation of daprodustat may contribute to late-onset bioprosthetic valve thrombosis, highlighting the need for careful monitoring in patients with risk factors.
UNLABELLED: Bioprosthetic valve thrombosis (BVT) is a rare complication following surgical valve replacement, with a particularly low incidence of 0.3% reported for the Epic bioprosthesis (St. Jude Medical, Inc., St. Paul, MN, USA) in the mitral position. We report a case of late-onset BVT of the Epic mitral bioprosthesis, resulting in significant prosthetic valve dysfunction. A 74-year-old man was admitted with acute heart failure 5.5 years after undergoing mitral valve replacement with a 29-mm Epic bioprosthetic valve. Although he had been taking edoxaban for paroxysmal atrial fibrillation, it was discontinued one year prior to admission. Moreover, daprodustat was initiated for renal anemia six months before admission. Transthoracic echocardiography on admission revealed severe mitral stenosis, with a mitral valve area of 0.8 cm LEARNING OBJECTIVE: We report a case of late-onset bioprosthetic valve thrombosis (BVT) of the Epic mitral bioprosthesis. In this case, discontinuation of edoxaban combined with initiation of daprodustat likely contributed to BVT. These findings underscore the importance of maintaining long-term anticoagulation in patients with risk factors for BVT and of carefully monitoring for thrombotic events in patients receiving hypoxia-inducible factor prolyl hydroxylase inhibitors.
Kuwano et al. (Mon,) conducted a case report in Bioprosthetic valve thrombosis (n=1). Discontinuation of edoxaban and initiation of daprodustat was evaluated on Bioprosthetic valve thrombosis. Discontinuation of edoxaban combined with initiation of daprodustat likely contributed to late-onset bioprosthetic valve thrombosis of an Epic mitral bioprosthesis in a 74-year-old man.
