In this study the STS/ACC Transcatheter Valve Therapy registry was used to compare TAVI in nonogenarians versus TAVI in patients <90 years old. In total 3,773 (15.7%) of the patients were >90 years old. Mortality at 30 days and 1-year was significantly higher for nonogenarians (8.8% vs. 5.9%, p<0.001 and 24.8% vs.

This instructive paper includes three separate meta-analyses focusing on patient-prosthesis mismatch (PPM) after TAVR. These meta-analyses revealed the following:
March 7, 2016
This literature review evaluated 21 studies that included nearly 4000 patients having undergone transcatheter aortic valve implantation (TAVI), specifically focusing on prosthesis-patient mismatch (PPM). Overall prevalence of PPM was 35%, with 8% of patients having severe PPM. PPM occurred less often after TAVI than after surgical AVR. PPM was not

In this prospective study on 377 patients, the authors evaluate the effect of the application of a patient-specific transcatheter heart valve (THV) selection algorithm, which suggests the use of a specific THV (CoreValve or SAPIEN XT) for specific anatomical subsets, on procedural outcomes.

This video shows a right axillary Edwards SAPIEN 3 TAVR implanted through the new apical Certitude delivery system, in a patient with severe aortic stenosis. The postoperative follow-up was uneventful and the patient was discharged home on postoperative day three.

In this manuscript the authors report on the results of a retrospective propensity score analysis in 102 matched pairs of patients, considered to be in a “grey zone” of surgical risk for either TAVI (Edwards Sapiens, Medtronic CoreValve or Symetis Acurate TA prosthesis) or aortic valve replacement (AVR) with a sutureless prosthesis (Sorin Perceal).

The effects of renal failure on outcomes of AVR were examined using CMS data. TAVR pts on dialysis, TAVR pts not on dialysis, and surgical AVR pts on dialysis were compared after propensity score matching. In TAVR patients, dialysis was associated with increased 30 day mortality and survival, and was an independent predictor of worse survival. TAV

Patients entered into a clinical trial of TAVR and patients in two registries were evaluated for possible subclinical leaflet thrombosis in their bioprosthetic valves. 40% of the patients in the TAVR trial and 13% of registry patients were found to have such thrombosis. The risk was lower in patients anticoagulated with warfarin. Therpeutic antico
