Abstract

Feasibility of transfemoral (TF) transcathteter aortic valve replacement (TAVR) is limited by the smallest diameter, the calcification and tortuosity of the iliofemoral access vessels. The use of the Portico system without delivery sheath results in significantly lower profile delivery system compared to standard technique. We herein report our single center experience, feasibility and safety of such an approach. The Portico valve was implanted sheathless in 81 high-risk patients with severe aortic stenosis utilizing percutaneous femoral access. Mean minimal diameter of the ileo-femoral arterial access was 7.06 ± 1.89 mm. In most cases a multidetector computed tomography was performed before the intervention to assess the feasibility of vascular access and for aortic annulus measurements. The vascular access site was preclosed using two ProGlide suture systems. Device implantation was successful 98.7% of patients. Valve recapturing and repositioning as well as valve-in-valve deployment was performed in only one case (1.2%). There were no infarctions, 2 strokes (2.4%) and 2 acute kidney failure (2.4%), 1 major vascular complication1 (1.2%) 4 major bleedings (4.9%), 11 conductions disturbances and relative pace-maker implantation...Continue Reading
