Key result
Full-root implantation of stentless aortic xenografts allows for the implantation of a 3-4 mm larger valve to avoid prosthesis-patient mismatch in patients with small aortic roots.

May allow larger valves in small aortic roots to avoid mismatch; leaves open comparative outcomes versus standard implantation.
Tavakoli et al. (2017) studied Small aortic roots necessitating aortic valve replacement. Full-root implantation of stentless aortic xenografts vs. Classical aortic valve replacement with stented pericardial valves was evaluated. Full-root implantation of stentless aortic xenografts allows for the implantation of a 3-4 mm larger valve to avoid prosthesis-patient mismatch in patients with small aortic roots.
