Effect of preoperative right ventricular dysfunction and dilatation on survival after left ventricular surgical restoration

Abstract Background This study investigated the impact of preoperative right ventricular (RV) dysfunction and dilatation on survival outcomes following left ventricular surgical restoration (LVSR) in patients with ischemic cardiomyopathy. A retrospective analysis was conducted on 137 patients who underwent LVSR between 2009 and 2021. Results The results indicated that hospital mortality was significantly associated with older age [OR, 1.10; P = 0.01], higher EuroSCORE II [OR, 1.08, P = 0.03], recent myocardial infarction [OR, 4.24, P = 0.02], lower creatinine clearance [OR, 0.97, P = 0.02], and left ventricle longitudinal [OR, 0.95, P
