Prophylactic percutaneous circulatory support in high risk transcatheter aortic valve implantation

摘要

Mechanical circulatory support in transcatheter aortic valve implantation (TAVI) procedures is a useful solution for both planned and in emergent cases and provides prophylactic implantations which can subsequently avoid complications. Venoarterial extracorporeal membrane oxygenation (VA-ECMO) provides both hemodynamic and oxygenation support. Percutaneous VA-ECMO can be inserted with fluoroscopy or ultrasound guidance. A perfusion cannula is required to protect against distal limb ischemia. VA-ECMO can either be used in prophylactic settings or as a rescue therapy [1–4].
