Selection of Prosthesis in Aortic Valve Surgery: Short Review and Trend in our Practice in 10 Years

Le résumé fourni par la source

Introduction: In our country, the predominant condition treated in aortic valve surgery in its early stages was aortic valve disease of rheumatic origin, primarily in patients under the age of 60. In recent decades, due to lifestyle changes, increased average lifespan, and a shift in surgical treatment concepts among the elderly, there has been a noticeable trend towards atherosclerotic aortic valve disease treated surgically. This condition poses challenges in selecting the type of prosthesis for surgical replacement—either bioprosthetic or mechanical. The replacement of the aortic valve, aside from its undeniable benefits for patients, also introduces various complications, such as bleeding related to anticoagulation, thromboembolism, prosthetic endocarditis, and structural degeneration of the prosthesis. These complications vary between the two main groups of prostheses: bioprosthetic and mechanical. In this context, we are confronted with the challenge of selecting the type of prosthesis suitable for each patient. This paper presents current issues regarding selecting aortic valve prostheses, considering factors related to the prosthesis and the patient. We will also discuss the trends in prosthesis usage in our country over the past decade. Materials and Methods: We reviewed the types of mechanical and bioprosthetic valves used over the past ten years at our clinic, the Cardiac Surgery Service of the University Hospital Center "Mother Teresa.” We consulted articles, studies, and guidelines for managing heart valve diseases from European and American cardiology associations. Conclusion: The choice of prosthesis for aortic valve replacement remains a current issue, involving considerations of patient-related and prosthesis-related factors. The decision is based on guidelines recommendations, surgical team judgment, and patient preference, following a detailed explanation of the benefits and risks associated with each type of prosthesis.
