RESULTS OF PERCEVAL IMPLANTATION IN PATIENTS WITH AORTIC STENOSIS IN NARROW AORTIC FIBROUS ANNULUS

Objective: To evaluate hemodynamic parameters after implantation of Perceval prostheses of quick deployment, as well as various complications that arose in patients in the early and long-term postoperative period (6 months). Material and methods: We performed 20 implantations of Perceval prostheses of quick deployment in a narrow fibrous ring. The function of the prosthesis was evaluated in the postoperative period on the 7-10th day and after 6 months. The patients underwent echocardiographic examination before the intervention, in the early and long-term postoperative period. Results: The analysis of the results of echocardiography showed rather low values of pressure gradients on the aortic valve and rather large values of the effective and indexed area of the valve opening in patients after implantation of Perceval prostheses. Conclusions: According to the results of echocardiographic study, implantation of Perceval prostheses is associated with low average and peak pressure gradients on the aortic valve and the effective area and indexed effective area of the valve opening.
