Phase-resolved velocity measurements in the Valsalva sinus downstream of a Transcatheter Aortic Valve.

Two sets of phase resolved PIV measurements were performed in the Valsalva sinuses of a glass mock aortic root including three polymeric valve leaflets, before and after the implant of a Medtronic CoreValve TAVI device. The experiments were carried out in a hydro-mechanical cardiovascular pulse duplicator system (Vivitro Superpump System SP3891) r...
