Vascular access closure in TAVI procedures

Transcatheter Aortic Valve Implantation (TAVI) has become a key treatment option for severe aortic stenosis (AS).The invasive character in its earlier years -where the use of general anesthesia and extra corporeal membrane oxygenation (ECMO) was standard- has been replaced by a minimalist approach, using local anesthesia and as little invasive measures as possible. Alongside this transformation, vascular access- and closure has shifted from surgical- cutdown and closure towards a completely percutaneous strategy using ultrasound for access and vascular closure devices (VCD) for closure.11.

Large-bore vascular access is needed to accommodate the big caliber sheaths used in TAVI. Although device- and delivery system alterations have led to smaller size, the sheath sizes used in TAVI still vary from 14 to 18 French.22.
