Light physical activity is allowed after aortic valve replacement, but bed rest, monitoring of vital signs, and prevention of complications are recommended. Light physical activity, such as slow walking, may be appropriate after surgery. Heavy physical activity may cause complications such as heart block, bleeding, aortic dissection, arterial blockage, etc., and the complications may make the condition more serious, so strenuous exercise should be avoided after the operation (e.g., running, doing physical work, lifting things, etc.), and it is recommended to rest in bed as much as possible, and to carry out antithrombotic and anticoagulant treatments. Appropriate activities should be carried out 3 months after the operation, and the activities should be carried out only after professional evaluation and the doctor’s approval of being able to get out of bed, and the intensity and duration of the activities are recommended to follow the doctor’s instructions, and go to the hospital for checkups in case of any discomfort.
