The wound of open heart surgery usually heals in about two weeks, and normal patients usually have their wounds healed in about nine days, so you can consider removing the sutures, but complete healing usually takes about two weeks. Compared with abdominal surgery wounds, open chest surgery wounds are longer in length and take longer to heal, so the pain of local surgery may be more pronounced after the wounds have healed. The incision may be made through the middle of the sternum or along the rib cage, so special sutures may be used during the suturing process, and the blood supply to the chest is relatively small, so the healing time is also long.
