Transapical versus transfemoral aortic valve implantation: a comparison of survival and safety.
نویسندگان
چکیده
BACKGROUND Transcatheter aortic valve implantation (TAVI) is a therapeutic option for high-risk patients with aortic stenosis. Procedural mortality remains high in comparison with conventional aortic valve replacement (AVR) because patients determined for TAVI are commonly denied conventional surgery. We aimed to evaluate access-related complications between the transfemoral (TF) and the transapical (TA) approach and to compare survival between TAVI and conventional AVR in propensity-score-matched patients. METHODS Between January 2008 and November 2009, 40 patients underwent TAVI (TF, n=10; TA, n=30) with the Edwards Sapien bioprosthesis (Edwards Lifesciences, Irvine, CA). Survival and postoperative complications were evaluated between the TF and the TA approach. A comparison of survival was made between the TAVI patients and propensity-score-matched patients undergoing conventional AVR. RESULTS Successful implantation rate was 92.5% (37 of 40). Thirty-day mortality was 5.0% (2 of 40), and the overall in-hospital mortality was 10.0% (4 of 40). Survival after TAVI was 77% at both 6 months and 1 year. Major vascular complications occurred in 3 of 10 patients (all in the TF group), and 3 of 40 patients (7.5%) suffered cerebrovascular events. A comparison of survival between TAVI and propensity score-matched conventional AVR patients showed no significant difference in either the TA group (p=0.73) or the TF group (p=0.59). CONCLUSIONS The vascular complications occurring when using the TF approach were probably related to a combination of a wide introducer sheath and heavily calcified femoral arteries in a high-risk population. No serious complications were encountered when using the TA approach. After propensity-score matching, survival with both the TA and TF approaches is similar to that after AVR.

متن کاملNetwork meta-analysis on the comparative effectiveness and safety of transcatheter aortic valve implantation with CoreValve or Sapien devices versus surgical replacement
INTRODUCTION Surgical replacement for aortic stenosis is fraught with complications in high-risk patients. Transcatheter techniques may offer a minimally invasive solution, but their comparative effectiveness and safety is uncertain. We performed a network meta-analysis on this topic. METHODS Randomized trials on transcatheter aortic valve replacement vs surgery were searched. The primary out...
