Clinical impact of multiple resheathing during transcatheter aortic valve implantation with Evolut self-expanding valves.

Background: The possibility to resheath some transcatheter heart valves (THV) facilitates the optimization of self-expandable devices implantation. However, resheating manoeuvres (expecially when repeated) increase the interaction between the transcatheter prosthesis and the patient's tissues potentially causing side-effects.

Aims: To assess the clinical outcomes of resheathing at midterm follow-up with a focus on the safety of multiple resheathing.
