Transfemoral versus transapical transcatheter aortic valve implantation ...
2018年11月9日 · The actual predominant opinion on transcatheter aortic valve implantation (TAVI) for high-risk patients is that regarding short- and mid-term mortality TAVI is non-inferior to surgery and probably superior, if a transfemoral (TF) access can be used . Alternative access routes for TAVI, especially the transapical (TA) approach, are increasingly ...
Transcatheter Aortic Valve Implantation: All Transfemoral?
Abstract. Transfemoral access remains the most widely used peripheral vascular approach for transcatheter aortic valve implantation (TAVI). Despite technical improvement and reduction in delivery sheath diameters of all TAVI platforms, 10–20% of patients remain not eligible to transfemoral TAVI due to peripheral artery disease.
What is TAVR? (TAVI) - American Heart Association
2024年6月7日 · The surgery may be called a transcatheter aortic valve replacement (TAVR) or transcatheter aortic valve implantation (TAVI). Valve-within-valve — How does it work? Somewhat similar to placing a stent in an artery, ... Transfemoral approach: Entering through the femoral artery (large artery in the groin), which does not require a surgical ...
Management of Vascular Access in Transcatheter Aortic Valve Replacement ...
Transfemoral TAVI can be considered the least invasive approach and is therefore the most widely used access for TAVI. With the current 18-F to 24-F sheaths, the majority of patients can be treated via the transfemoral route. Initially, open surgical access was routinely used to introduce the large sheaths and catheters. ...
Transfemoral transcatheter aortic valve replacement for pure …
2024年4月13日 · Surgical aortic valve replacement continues to be the preferred method for treating severe aortic regurgitation.1 For patients who encounter prohibitively high surgical risks, transcatheter aortic valve implantation (TAVI) is increasingly becoming a viable substitute. Originally developed for treating aortic-valve stenosis in patients with high surgical risk, TAVI's role has expanded to ...
Plugging the gap: vascular access closure after transfemoral ...
4 天之前 · The indication for TAVI was adjudicated by the local multi-disciplinary heart teams, and participants with hostile anatomy not suitable for transfemoral TAVI or vascular closure devices were excluded. All participants underwent computed tomography (CT) assessment of their femoral vasculature for calcification, tortuosity, and bifurcation height.

2024年9月9日 · Aortic valve replacement (AVR) is the mainstay of treatment of symptomatic severe aortic stenosis (AS). The role of transcatheter aortic valve implantation ... In an analysis of data from the Transcatheter Valve Therapy Registry on 96,256 transfemoral TAVI procedures during 2015 to 2017 at 554 hospitals, adjusted 30-day mortality was higher and ...
Transapical vs. transfemoral aortic valve implantation: Which …
2012年7月26日 · Transcatheter aortic valve implantation (TAVI) has gained increasing acceptance for treating patients with severe aortic stenosis (AS), especially in the presence of a higher risk profile. The procedure is performed a number of ways, however, the two main routes of access are the transfemoral (TF) retrograde approach and the transapical (TA ...
Transfemoral TAVI devices: design overview and clinical outcomes
Devices for transfemoral transcatheter aortic valve implantation (TAVI). Balloon-expandable valves. Conceptually, all balloon-expandable valves consist of biological cardiac valve tissue sewn inside an expandable stent frame, which is subsequently crimped onto a balloon whose expansion results in valve deployment. Deployment requires rapid ...
Percutaneous management of vascular access in transfemoral ...
2014年8月8日 · INTRODUCTION. Transcatheter aortic valve implantation (TAVI) using stent-based bioprostheses has recently emerged as a promising alternative to surgical valve replacement in selected patients[1,2].At present, for transfemoral TAVI the most studied valves are a balloon-expandable prosthesis, the Edwards SAPIEN XT™ valve (Edwards Lifesciences, Irvine, California, United States), that has ...
