Experimental Investigation of Left Ventricular Flow Patterns After Percutaneous Edge‐to‐Edge Mitral Valve Repair

This in vitro study aims to evaluate the hemodynamic modifications following a simulated PEtER. A custom-made mitral valve was developed, and two configurations were tested: (i) a single-orifice valve with mitral regurgitation and (ii) a double-orifice mitral valve configuration following PEtER. … MATERIALS AND METHODS In vitro model For the purpose of this study, a ViVitro pulse duplicator (ViVitro Labs, Victoria, BC, Canada) was used (Fig. 1). This system is capable of reproducing physiological flow and pressure waveforms in left heart cavity models …
