Objective — to analyze myocardial scar tissue and left ventricular (LV) remodeling using MRI, early and long-term results of LV repair using echocardiography and the Minnesota Living with Heart Failure Questionnaire. Material and methods. A retrospective analysis included 16 patients with complicated coronary artery disease who underwent surgery at the cardiac surgery department of the Moscow Regional Research Clinical Institute in 2016—2017. All patients had previous acute myocardial infarction followed by chronic anterior-septal-apical LV aneurysm. All patients underwent LV reconstruction. Results. In-hospital and long-term mortality was absent. Mean follow-up was 2.6 years. There were significant increase of end-diastolic volume (EDV) and decrease of LV ejection fraction prior to surgery. Postoperative period was characterized by significant reduction of LV dimensions and scar mass. According to echocardiography, preoperative EF was 42.1±10%, after surgery — 46.9±8.2%, in long-term period — 47.2±7.1% (p>0.05). Mean EDV before surgery was 154.5±39.4 ml, after surgery — 117.2±17.9 ml, in long-term period — 121.4±14.6 ml (p<0.05). According to MRI, preoperative EF was 36.1±9.8%, after surgery — 44.9±9.2%, in long-term period — 41.2±5.1% (p>0.05). Scar mass prior to surgery was 45.1±19.3 g, after surgery — 25.4±9.8 g (p<0.05). An improvement of the quality of life was revealed according to the Minnesota Living with Heart Failure Questionnaire. Conclusion. Patients with angina pectoris functional class III—IV and low EF may be successfully operated. Myocardial revascularization with LV repair is accompanied by favorable clinical result. Patients note an improvement of the quality of life that is evidenced by clinical and instrumental studies and the Minnesota Living with Heart Failure Questionnaire.
