Cardiac rehabilitation for TAVR patients: mechanisms, current status, and future directions.

Due to the aging population, the prevalence of aortic stenosis continues to rise, transcatheter aortic valve replacement (TAVR) has become an important method for treating severe symptomatic aortic stenosis. Although TAVR significantly improves the survival and symptoms of patients with aortic stenosis, this population is generally characterized by advanced age, frailty, and multiple comorbidities, posing challenges to postoperative functional recovery and quality of life improvement. Cardiac rehabilitation (CR) constitutes a cornerstone of secondary prevention for cardiovascular disease (CVD), and plays a pivotal role in optimizing outcomes for patients undergoing TAVR. This review aims to discuss the mechanistic, current practical evidence, existing challenges, and future directions of CR in TAVR patients.
