RESUMEN
PURPOSE: To compare immediate results of mitral valve surgery in patients with severe pulmonary hypertension with versus without concomitant pulmonary artery denervation. MATERIALS AND METHODS: From January to December 2015 30 patients were randomly assigned into two groups. Patients of one group underwent mitral valve surgery (comparison group), in the other group mitral valve surgery was accompanied by pulmonary artery ablation (ablation group). Both groups had comparable anthropometric, echocardiographic, and hemodynamics characteristics. RESULTS: There were no hospital mortality and specific ablation-related complications. Left ventricular remodeling and decrease of pulmonary artery pressure were observed in both groups at discharge. On the third day after surgery systolic and mean pulmonary artery pressure assessed by right heart catheterization were 48 and 22 versus 59 and 39 mm Hg in ablation and comparison group, respectively (p.

AIM: To evaluate prospectively the hemodynamic performance of «BiolAB Mono¼ stentless bioprosthesis implanted into aortic position. MATERIAL AND METHODS: Twenty seven patients (mean age 71 (67; 73); 17 women) with severe aortic stenosis underwent, aortic valve replacement with «BioLAB Mono¼ stentless bioprosthesis from 2012 to 2014. The valves- were implanted into supraannular position using continuous polypropylene suture. RESULTS: In the early postoperative period 1 patient (3.7%) died for acute heart failure. The mean aortic cross-clamping time was 81 (75; 90) min. Echocardiographic peak pressure gradient were 18 (16;23) mmHg (postoperative). There were no cases of valve dysfunction In early 'postoperative period. Level of thrombocytes recovered after 1 O days postoperatively. CONCLUSION: «BioLAB Mono¼ aortic bioprosthesis implantation. is easy and reproducible. The valve has excellent hemodynamic performance ir;i early postoperative period.

442 patients underwent the mitral valve replacement (MVR) with KemCor and PeriCor stented bioprostheses. The study results justified the preference of the "totally biological" PeriCor valve in patients with active infectious endocarditis. The longest follow-up period was 11 years, the mean follow-up was 51±34 months. The risk of the structural valve disfunction was shown to be inversely proportional to the age (p=0.03). 38% of the operated women younger the 45, developed the structural valve disfunction in 79±27 months after surgery. Thus, MVR with stented bioprostheses proved to be clinically efficient early after the operation. Predictability of the results of KemCor and PeriCor valve implantation allows the theoretically substantiated approach to the rehabilitation, especially, considering the adverse event rate in different patient groups at certain follow-up periods.
