Increased Left Ventricular End-Diastolic Volume Index Is Associated With Increased Adverse Events After MitraClip Implantation

This study investigated the association between the left ventricular end-diastolic volume index (LVEDVI) and the incidence of adverse clinical events in patients after MitraClip implantation. In this retrospective, observational study, 123 patients who underwent the MitraClip procedure were enrolled. Participants were divided into 2 groups according to the LVEDVI cut-off level, calculated using receiver operating characteristic curve analysis, to predict the primary end point and the occurrence of cardiovascular events was compared between the groups. The primary end point was all-cause mortality and hospitalization because of heart failure. The receiver operating characteristic curve analysis for the composite primary end point revealed an LVEDVI cut-off point of 118 ml/m . Based on this threshold, 61 patients (49.6%) were categorized into the LVEDVI
