Acute kidney injury after MitraClip implantation in patients with severe mitral regurgitation

Introduction Percutaneous mitral valve repair (PMVR), such as MitraClip, is performed on high‐risk patients and involves hemodynamic alternations that may cause acute kidney injury (AKI). We aimed to evaluate the incidence of AKI, predictors for developing AKI and the correlation with mortality after MitraClip. Methods We performed a retrospective analysis of collected data from patients who underwent PMVR in two tertiary medical centers in Israel to identify factors associated with AKI. Results The study population included 163 patients. The median age was 77 years; 60.7% of patients were male. The median eGFR significantly decreased post‐procedure from 49 (35–72) to 47.8 (31–65.5) ml/min/1.73 m2 (p 5 mmHg, diuretic use, and re‐do procedures. Among the patients who developed AKI there was an improvement in kidney function during follow‐up, and creatinine levels significantly decreased from a peak mean creatinine of 179.5 (143–252) mmol/l to 136 (92–174) mmol/l (p
