Balloon expandable sheath for transfemoral aortic valve implantation: a viable option for patients with challenging access

J Interv Cardiol. 2013 Feb;26(1):84-9. doi: 10.1111/j.1540-8183.2012.12013.x.

Abstract

Background and objectives: Transcatheter aortic valve replacement (TAVR) via femoral access is a new option for patients with severe aortic valve stenosis considered to be at high risk for conventional open-heart surgery. This procedure requires peripheral arteries that are able to accommodate the large sheaths required for valve delivery. We present a series of patients with suboptimal vascular conditions, who received a self-expandable vascular sheath.

Methods and results: From January 2009 to September 2011, a total of 96 patients (43% male) were treated with the 18F Medtronic CoreValve (Medtronic, Minneapolis, MN, USA). The patients' average age was 82.5 ± 4.6 years, and the mean EuroSCORE was 29%. In eight cases, vascular conditions were inadequate either due to advanced atherosclerotic disease (n = 5, 62.5%), or an arterial diameter ≤7 mm (n = 3, 37.5%). Instead of the standard 18F sheath, a balloon-expandable transfemoral introducer (SoloPath Introducer, Onset Medical Corporation, Irvine, CA, USA) was delivered and removed without complications in all but one (87.5%) patient. In the last case, rupture of the right femoral artery occurred after removal of the sheath with the need of vascular surgery.

Conclusion: The SoloPath sheath is a feasible alternative to conventional sheaths for transfemoral TAVR patients with difficult femoral vascular access.
