MitraClip implantation is one possible method of treatment of patients with heart failure and severe mitral regurgitation. Goal. Analysis of clinical and echocardiographic data of patients 1 year after MitraClip implantation. Methods The first 63 consequtive patients whom underwent MitraClip implantation at our cardiocentre were analyzed. Implantation was performed after all possible conservative treatment options according to guidelines were exhausted. Each patient underwent careful clinical and echocardiographic examination before and 12 months after implantation. Results Average age of the patient population was 70,5 ± 7,4 years. Baseline average ejection fraction (EF) of left ventricle (LV) was 35,2 ± 12,6%, enddiastolic volume of LV 196 ± 53ml, 63 (100%) had mitral regurgitation (MR) ≥ 3/4, average ERO 27,4 ± 10,2cm2 RV 40,5 ± 12,9ml. During 1 year follow-up 11 (17%) of patients died, 1 (1,6%) from a periprocedural complication. In the patients who survived we observed a decreasing incidence of severe mitral MR , (MR ≥ 3/4 before procedure in 63 (100%) vs. 12 (19%) in patients after procedure). A significant improvement in functional class NYHA (NYHA II-IV before implantation in 63 (100%) patients vs. 17 patients (33%) at one year follow-up). Mortatility was mostly influenced by Euroscore (p 0,08), creatitnine level (p 0,10), from echocardiographic parameters LV EF (36,4% vs. 29,5% p 0,10) and TAPSE (17,8 vs. 15,2mm p 0,04). Conclusion One year mortality in our study population was comparable with previously published data from larger registries. Significant regression of mitral regurgitation and improvement of symptoms was observed in patients after implantation. Moratility was affected by comorbidities, and systolic function of left and right ventricle.
