Abstract：Objective To analyze the clinical efficacy and safety of robot-assisted mitral valve replacement for mitral lesions.Methods The clinical data of 60 patients with mitral lesions who received surgical treatment in the University of Hong Kong-Shenzhen Hospital from July 2020 to February 2023 were retrospectively analyzed.Among the 60 patients,30 patients who received robot-assisted mitral valve replacement were included in the observation group and 30 patients who received traditional median sternotomy for mitral valve replacement were included in the control group.The therapeutic outcome indicators,clinical outcomes and complications were compared between the two groups.Results There was no significant difference in connecting time,time for cardiopulmonary bypass support after the aorta was opened and ventilator supporting time between the two groups(P＞0.05).The aortic cross-clamp time and operation time in the observation group was longer than that in the control group,and the drainage volume and intraoperative blood loss in the observation group were less than those in the control group,and the wound healing time in the observation group was shorter than that in the control group,and the differences were statistically significant(P＜0.05).The improvement rate of clinical outcome was 96.67%in the observation group and 93.33%in the control group,and there were no signifi-cant differences between the two groups(P＞0.05).The total incidence of complications was 13.33%in the observation group and 10.00%in the control group,and there was no significant difference between the two groups(P＞0.05).Conclu-sion Robot-assisted mitral valve replacement can effectively improve the therapeutic outcome indicators of the patients with mitral lesions.Its safety is relatively good and worthy of promotion.
