Cardiac rehabilitation (CR), particularly regular exercise, can improve the cardiopulmonary function, exercise capacity, and quality of life for patients undergoing transcatheter aortic valve implantation (TAVI). Consequently, the patients after TAVI will be enrolled in our randomized controlled trial to demonstrate if the moderate-intensity continuous training (MICT) can improve the cardiopulmonary function compared with the control group after receiving treatment for 12 weeks. Moreover, we will provide new insights regarding whether cardiac systolic function or cardiac diastolic function is mainly improved after regular exercise for TAVI patients. As a result, the principal hypothesis of our study is that MICT will improve the cardiopulmonary function and can extremely affect the cardiac diastolic function of patients with TAVI after the implementation of exercise for 12 weeks.
