Rare complication of bioprosthetic aortic valve replacement.
CE-Perimount aortic bioprosthesis in a 59-year-old-man, implanted 8 years ago, showed non-infective severe structural deterioration. Preoperative echocardiogram demonstrated a prolapsing cusp (Fig. 1(A—C)); however, intra-operative echocardiogram and findings revealed a ‘missing’ leaflet (Figs. 1(D), 2(A and B) and Video 1). www.elsevier.com/locate/ejcts European Journal of Cardio-thoracic Surg...
متن کاملAntithrombotic therapy following bioprosthetic aortic valve replacement.
The life expectancy of the general population is increasing. This has meant that more elderly patients are requiring aortic valve replacement (AVR). The choice of valve replacement and its durability are important. Bioprosthetic (tissue) heart valves were introduced into clinical use in the 1960s and were developed primarily to reduce the complications associated with thromboembolism (TE) and t...
متن کاملTranscatheter aortic valve replacement for bioprosthetic aortic valve failure: the valve-in-valve procedure.
2542 B ioprosthetic valves are increasingly used in patients with aortic stenosis. Compared with mechanical valves, bio-prosthetic valves are associated with a lower risk of thrombo-embolic events and do not require long-term anticoagulation. 1,2 However, bioprosthetic valves have limited durability; the best current valves can be expected to degenerate within 10 to 20 years, resulting in steno...
متن کاملCandida parapsilosis bioprosthetic valve endocarditis inducing aortic valve stenosis.
A 59-year-old woman was admitted with a presumptive diagnosis of infective endocarditis of a prosthetic aortic valve. Six months earlier, she had undergone aortic valve replacement with a porcine valve for the treatment of aortic valve regurgitation, replacement of the ascending aorta with a Dacron tube-graft, a Cox maze operation, and tricuspid ring annuloplasty. Transthoracic echocardiograms ...
متن کاملBioprosthetic Valve Fracture Improves the Hemodynamic Results of Valve-in-Valve Transcatheter Aortic Valve Replacement.
BACKGROUND Valve-in-valve (VIV) transcatheter aortic valve replacement (TAVR) may be less effective in small surgical valves because of patient/prosthesis mismatch. Bioprosthetic valve fracture (BVF) using a high-pressure balloon can be performed to facilitate VIV TAVR. METHODS AND RESULTS We report data from 20 consecutive clinical cases in which BVF was successfully performed before or afte...
