| Popis: | Aim. To assess the severity of heart failure (HF) 1 year after aortic valve replacement with a novel bioprosthetic valve with the “easy change” system.Material and methods. The study included 59 patients (24 men and 35 women) diagnosed with degenerative aortic valve disease without concomitant cardiac pathology. The mean age of the patients was 69,6±4,3 years. An assessment of NYHA HF class using six-minute walk test was carried out. The venous plasma level of N-terminal pro-brain natriuretric peptide (NT-proBNP) before and after surgery was also used to determine the severity of HF. In 31 patients (52,5%), NYHA class III HF was determined before surgery.Results. Comparative analysis of HF classes revealed a significant difference. Thus, after implantation of MedEng-BIO prosthetic aortic valve, the distance of the six-minute walk test increased by an average of 125 m (p=0,001). NT-proBNP level decreased from 162,2 pg/ml to 63,7 pg/ml (p=0,003).Conclusion. One-year follow-up of patients after implantation of a novel bioprosthetic aortic valve showed an objective decrease in the severity of HF according to six-minute walk test and NT-proBNP level in venous blood plasma. |
