“…The best complementary examination to refine the diagnosis of thrombosis is transesophageal echocardiography, which allows elucidation of the obstructive mass, leading to a more accurate diagnosis [6][7][8] . Reoperation, in such cases, increases the risk, with mortality rates ranging from 10% to 15% in some case series 3,4,9,10 4 has shown the following: an initial success rate of 82%; thromboembolic events in 12% of the cases; stroke in 5 to 10% of the cases; mortality rate of 6%; greater bleedings in 5% of the cases; and recurrence of thrombosis in 11%.…”

A 70-year-old man underwent mitral valve replacement using a porcine bioprosthesis for infective endocarditis. Transthoracic echocardiography revealed thickened leaflets with increased transprosthetic pressure gradient and new regurgitation, 6 months after surgery. He was followed up medically with the diagnosis of early valve degeneration. He ultimately presented with worsening orthopnea 13 months after surgery. Transesophageal echocardiography revealed an immobile round mass attached to the ventricular aspect of the leaflets, which hampered valve opening, suggesting bioprosthetic valve thrombosis. Anticoagulation with heparin and warfarin were effective and transthoracic echocardiography showed normal transprosthetic pressure gradient and disappearance of regurgitation 2 months later.

Bioprosthetic Valve Thrombosis

et al. 2018

Degenerative valve disease is on the rise with greater than 100,000 valve operations performed in the US alone per year. The majority of those procedures employ tissue bioprostheses to avoid the attendant risk of anticoagulation, especially in the elderly. Though traditionally this approach has been considered a superior option to avoid anticoagulation, more recent analyses have demonstrated a significant incidence of previously unrecognized thrombosis associated with bioprosthetic valves, especially with the more recent advent of the transcatheter aortic valve replacement implantations. Bioprosthetic valve thrombosis is a major cause of either acute or indolent bioprosthetic valve degeneration, and often has an elusive presentation causing delayed recognition and treatment. The literature has extensively addressed the risks and benefits of anticoagulation following bioprosthetic valve replacement to prevent bioprosthetic valve thrombosis (BPVT), without conclusive evidence-based recommendations. The duration of anticoagulation following an episode of BPVT is unclear, and lifelong anticoagulation has been suggested. The increasing use of transcatheter aortic valve replacement as an alternative to surgical aortic valve replacement in various risk groups has introduced new challenges with regards to valve thrombosis, which have been poorly studied with regards to optimal treatment and prevention. The increasing use of valve-in-valve procedures is expected to bring on further uncharted challenges.
