Snaring the Transcatheter Heart Valve Delivery System During Aortic Valve Replacement: When and Why

Cardiovasc Revasc Med. 2021 Jul:28S:81-84. doi: 10.1016/j.carrev.2021.02.018. Epub 2021 Feb 16.

Abstract

None of the commercially available self-expanding (SE)-trans-catheter heart valve (THVs) used for trans-catheter aortic valve replacement (TAVR) has a deflectable delivery system. This aspect can represent a shortcoming, especially in some anatomical scenario where THV advancement is challenging. The use of a snare catheter (SC), applying an external traction force, can increase THV trackability. We describe three different TAVR cases, in which a SE-THV was the only available option and where the THV delivery system advancement in the aortic arch was not feasible, if not with the combined use of a SC.
