The Study on the Use of "UniLine" Bioprosthesis in the Treatment of Isolated Aortic and Mitral Valve Diseases — Uniline  

Aortic Valve Disease Clinical Trial

Official title:
Open, Prospective, Multicenter Study of the Safety and Efficacy of "UniLine" Epoxy-treated Prosthesis Made From Xenopericardium in the Treatment of Isolated Aortic and Mitral Valve Diseases

Clinical Trial Summary

The goal of this open, prospective, multicenter study is analyze long-term outcomes of aortic/mitral valve replacement using the "UniLine" bioprosthesis in patients with acquired aortic or mitral valve diseases. Main research objectives: To analyze long-term (up to 12 years) outcome of aortic or mitral valve replacement using the "UniLine" bioprosthesis. To study the hemodynamic characteristics of normally functioning "UniLine " prostheses in the mitral or aortic valve position based on the transthoracic echocardiography data. To assess the number, type, time frames of dysfunctions of UniLine bioprostheses and the results of their treatment. To analyze the frequency of major serious adverse events associated with the "UniLine" bioprosthesis or procedure.

Clinical Trial Description

Acquired heart diseases (AHDs) remain one of the most frequent causes of cardiac mortality and disability. In Russia, this kind of disease accounts for 7 to 25 % of all cardiovascular diseases, and is third most common cause of heart failure. Heart valve replacement using a prosthetic heart valve remains the main and most effective method of treatment of AHDs. In Russia, AHDs are treated in more than 40 subjects by specialists from 92 medical institutions. Valve replacements, being high-tech methods of treatment, most effectively prolong the life of patients. Timely correction of AHD allows 75-95 % of patients to return to a normal lifestyle. The aim of this study is to evaluate the safety and effectiveness of the "UniLine" epoxy-treated bioprosthesis in the treatment of isolated mitral or aortic heart valve diseases. The expected clinical benefit involves the treatment of valvular disease with restoration of intracardiac hemodynamics during implantation of the "UniLine " bioprosthetic valve, followed by remodeling of the heart chambers, which should lead to an improvement in heart function and quality of life of the patient. The expected risks are associated with taking anticoagulant therapy during the first three months after implantation, or as a result of prolonged anticoagulant therapy, in the presence of concomitant rhythm disturbances, and consist in the possibility of hemorrhagic or thromboembolic complications. ;
