Intraventricular flow patterns, pressure distribution, and kinetic energy are closely linked to left ventricular function. Mitral valve opening generates a large clockwise vortex in the left ventricle (LV), that promotes inflow, reduces energy loss, and directs flow towards the outflow tract. This study examines in vitro, using two-dimensional Particle Image Velocimetry (PIV), the fluid dynamics of the Epygon transcatheter mitral valve (Affluent Medical), designed with a pericardial monoleaflet, D-shaped annular ring, and self-expanding nitinol frame to restore physiological LV hemodynamics. Experiments were conducted using the ViVitro Pulse Duplicator System, a left heart simulator. The working fluid used was a 0.9% w/v NaCl solution with spherical polyamide tracer particles.
