[Present and future of aortic valve selection based on the current guidelines].
According to the guidelines of the American Heart Association (AHA)/American College of Cardiology (ACC) and the Japanese Circulation Society, tissue valves have been chosen as the most appropriate aortic valve for patients older than 65 years old. The purpose of this study was to examine the propriety of our valve selection. In recent years, biologic prostheses for aortic valve replacement in patients younger than 65 years old are increasing because of the improved durability. Notably, 16% of the patients younger than 65 years old selected bioprosthetic valve after being informed of the advantages of anticoagulation free life and the risk of reoperation. On the other hand, only 6% of the patients older than 65 years old chose mechanical prostheses. The choice of aortic valves remains controversial and prospective randomized trials are needed to settle the disagreement.
