Abstract：Objective To evaluate the effect of mitral valvuloplasty(MVP)for the treatment of mitral incompetence(MI).Methods Totally 90 patients who underwent valve surgery for moderate to severe mitral regurgitation in Jiangmen Central Hospital,Guangdong Province from February 2019 to February 2021 were included in the study.Among them,44 patients underwent mitral valve replacement(MVR)surgery as the control group,and 46 patients underwent MVP as the observation group.Surgical performance indicators,postoperative cardiac ultrasound parameters[left atrial diameter(LAD),left ventricular end diastolic diameter(LVEDD),left ventricular ejection fraction(LVEF)],postoperative disease outcome indicators,and surgical efficacy during follow-up were compared between the two groups.Adverse cardiac events within 2 years after surgery were recorded in both groups.Results The surgical time,extracorporeal circulation time,chest closure time,ventilator usage time,intensive care unit hospitalization time,and extubation time in the observation group were shorter than those in the control group;the intraoperative bleeding volume and postoperative drainage volume in the observation group were lower than those in the control group,while postoperative LAD and LVEDD in the observation group were smaller than those in the control group;LVEF in the observation group was higher than that in the control group(all P＜0.05).The proportion of patients with mitral regurgitation greater than 3 ml in the observation group at 1 and 2 years after surgery was lower than that in the control group[4.3％(2/46)vs 20.5％(9/44),6.5％(3/46)vs 22.7％(10/44)](both P＜0.05).The incidence of adverse cardiac events within 2 years after surgery in the observation group was lower than that in the control group(P＜0.05).Conclusion MVP has an excellent therapeutic effect on MI,which can reduce surgical trauma and risk,improve cardiac function,promote early recovery,and have fewer complications.
