Long-term tracking of heart valve replacement outcomes across Asia and USA

This is a long-term registry study that tracks patients undergoing TAVR (transcatheter aortic valve replacement), a minimally invasive procedure to repair or replace a damaged aortic valve without open-heart surgery. Researchers at hospitals in Korea, Taiwan, and the United States are collecting information from thousands of patients to understand how well this treatment works over 10 years and what outcomes patients experience.

Many patients with aortic valve disease need treatment, but doctors want to understand the long-term safety and effectiveness of this newer, less invasive valve replacement approach compared to traditional surgery. This registry helps answer important questions about whether the treatment benefits last over time.
