Coronary Artery Bypass Lab Report

1. Procedure

Coronary Artery Bypass Graft (CABG) is performed when a patient has disease of the coronary arteries. This is usually caused by atherosclerosis which is clogging of the arteries or hardening by cholesterol of plaque. Coronary Artery Bypass is done to improve the blood flow of the heart. The surgeon bypasses the obstructed artery using a healthy artery that is harvested from another part of the body and placed in the heart to reroute the blood flow around the blocked area. Usually the healthy vein is taken from the patients leg or arm using a procedure called Endoscopic Saphenous vein harvest. To begin the Bypass graft the surgeon makes an incision in the middle of the chest, After the incision is made Sternotomy is performed. The Surgeon saws through the breastbone. Tubes are then inserted into the right atrium to passage blood out of the body through a lung heart machine. The outcome of this surgery is usually excellent.
There are two upper chambers of the heart and they are called the atria. These chambers obtain and collect the blood. The left atrium gathers the flow of oxygenated blood that goes back to the heart. The right atrium receives deoxygenated blood through the inferior and superior vena cava. The right side of the heart pumps the deoxygenated blood in the pulmonary veins around the lungs. The two inferior chambers of the heart are called ventricles. The ventricles pump blood beyond your heart to all parts of the body. In a healthy working heart the right atrium, pumps blood into the right ventricle. From the right ventricle, blood is pumped to your lungs throughout the pulmonary
