In the classical bypass operations, the cardiopulmonary pump device is used and the operation is performed while the heart is stopped.
In beating heart coronary bypass surgery, the operation is performed without stopping the heart. This technique can be employed in all patients with coronary artery disease. Beating heart method is preferred particularly in patients with impaired systole, chronic pulmonary disease, patients who had stroke in their past, with renal insufficiency, in 70+ age group, and patients with cancer. The purpose of preferring this method is to minimize the risk for high-risk group patients.
