A heart transplant is a surgical procedure that replaces a failing or damaged heart with a healthy heart from a deceased donor. This operation is typically recommended for patients with severe heart conditions, such as heart failure or coronary artery disease, when other treatments have failed. The goal is to improve the patient's quality of life and increase their chances of survival. Before a heart transplant, patients undergo a thorough evaluation to determine their eligibility. Once approved, they are placed on a waiting list until a suitable donor heart becomes available. After the transplant, patients require lifelong follow-up care and medications to prevent organ rejection.
