Cardiac surgery is a specialized branch of surgery dedicated to the treatment of heart conditions through surgical interventions. Also known as cardiovascular or thoracic surgery, it involves procedures performed on the heart and blood vessels to correct defects, manage diseases, and improve overall cardiac function. Common cardiac surgeries include coronary artery bypass grafting (CABG) to bypass blocked arteries, heart valve repair or replacement, and surgeries to treat congenital heart defects. Cardiac surgeons employ precise techniques, often utilizing cardiopulmonary bypass machines to temporarily take over heart and lung functions during complex procedures. Advances in minimally invasive techniques and robotic-assisted surgery contribute to improved patient outcomes and reduced recovery times in the field of cardiac surgery.
