| 概要 | 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/m2. Based on this threshold, 61 patients (49.6%) were categorized into the LVEDVI <118 ml/m2 group, whereas 62 (50.4%) fell into the LVEDVI ≥118 ml/m2 group. Over a median follow-up period of 336 days (interquartile range 80 to 667), the primary end points occurred in 15 and 26 patients in the LVEDVI <118 and LVEDVI ≥118 ml/m2 groups, corresponding to incidence rates of 24.6% and 41.9%, respectively. Patients in the LVEDVI ≥118 ml/m2 group demonstrated a significantly higher risk of adverse clinical events than those in the LVEDVI <118 ml/m2 group (hazard ratio 2.24, 95% confidence interval 1.17 to 4.28, p = 0.01). This trend persisted even after adjusting for several confounders (p = 0.02). In conclusion, increased LVEDVI values were associated with increased adverse clinical events after MitraClip implantation in patients with severe mitral valve regurgitation. |
