Abstract

A 69-year-old male underwent concomitant left ventricular assist device (LVAD) implantation and aortic valve repair procedure for moderate aortic insufficiency (AI). Due to recurrence of symptomatic heart failure and post-repair AI deterioration from trivial to moderate-to-severe insufficiency 2 months later, transcatheter aortic valve implantation (TAVI) was arranged. During TAVI, intraoperative extracorporeal membrane oxygenation was used to maintain stable haemodynamics and to ensure a safe environment for prosthesis deployment. Postoperative 5 month follow-up revealed no AI and no paravalvular leakage.
