Experimental Investigation of Left Ventricular Flow Patterns After Percutaneous Edge ‐to‐Edge Mitral Valve Repair
Abstract Mitral valve percutaneous edge‐to‐edge repair (PEtER) is a viable solution in high‐risk patients with severe symptomatic mitral regurgitation. However, the generated double‐orifice configuration poses challenges for the evaluation of the hemodynamic performance of the mitral valve and may alter flow patterns in the left ventricle (LV) during diastole. 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 ...

Should we touch tricuspid valve at the time of LVAD implantation? A young patient series
CONCLUSION: Although the risk of late RVF may increase in patients with preoperative severe TI, not intervening in TI during LVAD implantation does not cause adverse clinical outcomes in the early period.PMID:37334781 | DOI:10.1177/03913988231181604
