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 …Go to the Article
