Open heart surgery (OHS) is a type of surgery that involves opening the chest to access the heart. The procedure is typically performed under general anesthesia and requires the heart to be stopped and the blood to be redirected through a heart-lung machine. OHS is usually performed to treat conditions such as heart valve disease, coronary artery disease, and congenital heart defects. Some common OHS procedures include coronary artery bypass surgery, valve replacement or repair, and surgical correction of heart defects. The recovery time after OHS varies depending on the individual and the type of procedure performed, but most people are able to return to normal activities within a few weeks to several months.
