Abstract:
Objective To investigate the safety of totally thoracoscopic mitral valve reoperation with hypothermia-induced ventricular fibrillation arrest in elderly patients.Methods Clinical data of 108 elderly patients undergoing redo mitral valve surgery in our department from January 2008 to October 2024 were retrospectively collected,and according to surgical approach,they were di-vided into a totally thoracoscopic group(totally thoracoscopy with hypothermia-induced ventricu-lar fibrillation arrest,46 cases)and a median sternotomy group(cardiac arrest after median ster-notomy,62 cases).Their perioperative data were compared between the two groups.Results There were no statistical differences in baseline data between the two groups(P＞0.05).When compared with the median sternotomy group,the totally endoscopic group had significantly longer cardiopulmonary bypass time and higher mitral valvuloplasty rate and postoperative LVEF value,but obviously reduced lowest intraoperative temperature,lower blood transfusion rate,less vol-ume of suspended red blood cells transfused,decreased troponin T level 1 d postoperatively,shor-ter duration of mechanical ventilation and lengths of ICU stay and postoperative hospital stay,and less postoperative drainage volume(P＜0.05,P＜0.01).But there were no statistical differences between the two groups in terms of postoperative stroke(6.52％vs 3.23％,P=0.420)or in-hospital death(6.52％vs 6.45％,P=0.988).Conclusions Totally thoracoscopy with hypothermi-a-induced ventricular fibrillation arrest is safe and reliable for the elderly patients who need to receive mitral valve reoperation.
