After heart valve surgery, the chest is usually strapped for about 1 to 3 months. Heart valve surgery usually adopts the incision in the middle of the sternum, and after the surgery, it is fixed by wires and left in the body without removing. The first 3 months after surgery is the early postoperative period, at this time, in order to limit the amplitude of thoracic activity, to help the overall stabilization of the sternum, and to promote the healing of the chest, it is usually recommended to tie the chest belt fixed after surgery. Due to the different recovery conditions of individuals, the time of chest strap fixation also varies, basically it takes about 1 to 3 months. Heavy physical activities should be limited in the early postoperative period to avoid affecting the wound recovery. If you have recovered well in 3 months after the surgery and have no obvious clinical symptoms, you can gradually resume your normal life and work. If there is any postoperative discomfort or wound infection, it is recommended to consult a doctor as soon as possible to avoid delaying the condition.
