Transcatheter Aortic Valve Implantation in Failed Bioprosthetic Surgical Valves [1]
The consortium of authors of this paper determined the survival after Transcatheter valve in valve implantation inside a failed surgical bioprosthesis. The authors report a 1 month mortality rate of 7.6% and a major stroke rate of 1.7%. One-year survival was 83.2%, and 313 (92.6%) of survivors had a good functional status (NYHA I/II). Patients who had an aortic stenosis (n=181) had worse 1-year survival (76.6%) than patients with aortic regurgitation (91.2%) or combined stenosis/regurgigation (83.9%; p=0.01). Moreover, a small surgical bioprosthesis was associated with higher mortality.
