Heart surgery is done to fix different heart problems. There are many types of heart surgeries, such as coronary artery graft (CABG) surgery. Heart surgery can fix issues in the heart valves and arteries, improve blood flow, or substitute a sick heart entirely. Open-heart surgery is also called traditional heart surgery.
A ventricular septal disorder (VSD) - also known as a hole inside the heart - is a kind of congenital heart disorder. In a VSD, there is an abnormal opening within the wall among the main pumping chambers of the coronary heart (the ventricles). VSDs are the most common congenital heart defect.
