Transcript of Cardiac Surgery

Cardiac Surgery! Military surgeon, Dr. Dwight Harken was one of the first who started experimental surgeries on animals in trials where he would cut into the wall of the animal’s still beating heart, insert a finger, locate the shrapnel and remove it.

All of his patients survived, thus proving that the human heart could in fact be operated upon. Types of cardiac surgery CABG coronary heart disease causes plaque to build up inside the coronary arteries reducing the blood flow to the heart muscle During the procedure, the heart is stopped, and a heart-lung machine keeps blood moving throughout the body. Another type of cardiac surgery is Valve surgery in which one or two valves are repaired or replaced. Which way the procedure is carried out depends on the individual need of the patient. The location of the valve that needs to be repaired or replaced is also significant. Valve Surgery The procedure is carried out when there is a tear or aneurysm in the aorta. The aorta is the large artery that carries blood from the left ventricle of the heart to branch arteries. The traditional aortic surgery requires an incision into the sternum, where a surgeon then clamps off the aorta, removes the diseased or injured part of the aorta, and sews in a synthetic graft to act as a bridge for the blood to flow. Aortic Surgery involves making “new paths” for the electrical impulses occurring in the atrial chambers of the heart to travel through.
