Abstract: Objective To investigate the effects of the whole course of rehabilitation management during the perioperative period based on Omaha theory on psychological stress, 6-min walking distance(6MWD) and complications of patients undergoing transcatheter aortic valve replacement(TAVR). 
Methods A total of 74 TAVR patients in our hospital were selected and grouped according to the random number table method, with 37 cases in each group. The control group was given traditional perioperative care, and on the basis of the control group, the observation group was given the whole course of rehabilitation management during the perioperative period based on the Omaha theory. The complications, the degree of nursing satisfaction, psychological stress before and after nursing, cardiac function index, health promotionlifestyle profile-Ⅱ(HPLP-Ⅱ), 6MWD and quality of life were calculated in the two groups. 
Results After the intervention, the left ventricular end-diastolic diameter and transvalvular pressure difference in the observation group were lower than those in the control group, and the aortic valve area and left ventricular ejection fraction were higher than those in the control group(P＜0.05). The scores of trait anxiety inventory(T-AI) and state anxiety inventory(S-AI) in the observation group after intervention were lower than those in the control group(P＜0.05). The scores of 6 dimensions of HPLP-Ⅱ scale in the observation group were higher than those in the control group after intervention(P＜0.05). The quality of life and 6MWD in the observation group were higher than those in the control group at 3 and 6 months after operation(P＜0.05). The complications in the two groups were not significantly different(P＞0.05). 
Conclusion The application of whole course of rehabilitation management during the perioperative period based on Omaha theory to TAVR patients can alleviate their psychological stress, improve the health and lifestyle of patients, and prevent complications. It has positive significance in improving patients′ cardiac function and exercise endurance, and increasing the satisfaction degree of patients.
