Risk factors of chronic left ventricular dysfunction after cardiac valve surgery

Background To analyze the risk factors of chronic left ventricular dysfunction (LVD) after cardiac valve surgery. Methods A retrospective analysis of 860 patients who underwent heart valve surgery in our center from January 2017 to December 2018, including 650 males and 210 females, aged 58±5.8 years. Inclusion criteria: (I) the patient was clinically diagnosed with heart valve disease and met the surgical indications for mitral valve replacement (MVR), mitral valve repair (MVP), aortic valve replacement (AVR) and double valve replacement (DVR); (II) if atrial fibrillation, coronary artery disease, and tricuspid regurgitation are combined before surgery, radiofrequency ablation, coronary bypass and tricuspid angioplasty were performed contemporarily. Exclusion criteria: (I) preoperative LVEF 55 mm, preoperative LVESD >40 mm, preoperative combined atrial fibrillation, preoperative combined pulmonary hypertension, preoperative NYHA III-IV, and preoperative combined coronary artery disease were the risks of postoperative chronic LVD. Conclusions The left ventricular diameter, preoperative coronary artery disease, NYHA III-IV, preoperative atrial fibrillation, and preoperative pulmonary hypertension are risk factors for chronic LVD after heart valve surgery.
