Author : Robertas Pranevičius LSMU MA MF 20gr. Objective. To evaluate early post-operative outcome after (MV) annulus annuloplasty for degenerative MV insufficiency. Tyrimo uždaviniai : 1. To evaluate and compare the mitral valve operations results in early post-operative outcomes. 2. To evaluate the effectiveness of mitral valve operation and complications. Methods. The study was conducted in Lithuanian University of Health Sciences Kaunas Clinics Hospital Cardiothoracic and Vascular Surgery. Between 2015 and 2016, 140pts underwent MV repair annuloplasty. From 140, 61 pts underwent MV repair procedure because of degenerative factors which caused MV insufficiency. The study involved surgery patients with hemodynamically significant degenerative mitral regurgitation and mitral valve repair surgery was performed. For each patient before the operation the cardiac ultrasound was performed and repeated immediately after surgery to evaluate mitral valve regurgitation degree, regurgitation type. Mitral regurgitation grade was evaluated on the basis of standardized hospital adopted a scale from 1 to 4. All patient surveys and descriptions of operations has been collected and entered into the overall hospital system from which data was collected. The study was to evaluate the mitral valve echocardiographic examination data before surgery (valve condition), postoperative valve tightness in the early postoperative period and the operation-related data. Results. In-hospital mortality was 6,55 % (4/61), 1 patients (1,6 % ) had to undergo reoperation. From 140, 61 pts (24 male; 36 female; mean age 63±1,6) pts were included. Analyzed group of patients had arterial hypertension (AH) 43/61 (71,7 % ), arrhythmias 36/61 (60 % ), diabetes mellitus 7/61 (11.7 % ), smoking patients 15/61 (25 % ). Preoperative MV regurgitation grade was IVo in 24/61; 40 % patients, IIIo 27/61; 45 % , IIo -9/61; 15 % Early postoperatively (up to 2 weeks after operation): Io regurgitation - 54/61; 96,4 % , IIo - 2/61; 3,6 % (p<0,05). Mean preoperative LVEDD 54,67±7,68mm and 49,34±7,63mm (p<0,05), LVEF 47,8±11,5 % and 44,92±11,44 % (p
