Bioprosthetic valve durability after stentless aortic valve replacement: the effect of implantation technique.
BACKGROUND The Freestyle stentless bioprosthesis (FSB) (Medtronic Inc, Minneapolis, MN) is implanted using 2 techniques-subcoronary or aortic root replacement. Our objective was to determine whether the implantation technique had an impact on late reoperation for structural valve deterioration (SVD). METHODS Between 1993 and 2013, 531 patients underwent aortic valve replacement (AVR) or aorti...
متن کاملComparison of transcatheter aortic valve and surgical bioprosthetic valve durability: A fatigue simulation study.
Transcatheter aortic valve (TAV) intervention is now the standard-of-care treatment for inoperable patients and a viable alternative treatment option for high-risk patients with symptomatic aortic stenosis. While the procedure is associated with lower operative risk and shorter recovery times than traditional surgical aortic valve (SAV) replacement, TAV intervention is still not considered for ...
متن کاملRare 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...
