Heart surgery is a medical procedure that helps fix problems with the heart. Doctors perform this surgery to treat various conditions, such as heart disease, valve problems, or congenital heart defects. During the operation, surgeons may repair or replace damaged parts of the heart to improve its function and blood flow. There are different types of heart surgery, including bypass surgery and valve replacement. Patients usually stay in the hospital for a few days after the procedure to recover. With advances in technology and techniques, many people can return to their normal activities and enjoy a healthier life after heart surgery.
