| Popis: | Objective: To evaluate hemodynamic parameters after bioprosthetics of the aortic valve cusps, as well as complications arising in patients in the early and long-term period (6 months). Material and methods: 9 patients underwent bioprosthetics of the valves of the aortic valve with a narrow fibrous ring. The function of the cusps and left ventricle remodeling were evaluated on the 7-10th day and after 6 months. Results: Patients underwent echocardiographic examination before the intervention, in the early and long-term postoperative period. The analysis showed rather low values of pressure gradients on the aortic valve and rather large values of the effective and index area of the valve opening in patients after bioprosthetics of the aortic valve cusps. Conclusions: In the early postoperative period, prosthetics of the aortic valve leaflets with xenopericardium, according to an echocardiographic study, are associated with low average and peak pressure gradients on the aortic valve and a larger effective area and index effective area of the valve opening. The risk of the “patient-prosthesis mismatch” phenomenon with narrow fibrous rings is significantly lower with xenopericardial bioprosthetics than with standard prosthetics. |
