Which interventional procedure may be necessary for a patient with significant coronary artery blockage?

The choice of a coronary artery bypass graft (CABG) is appropriate for a patient with significant coronary artery blockage because this procedure is specifically designed to restore blood flow to the heart muscle when there are severe blockages in the coronary arteries. In cases where arteries are narrowed or blocked, CABG can reroute blood flow using a graft taken from another part of the body, such as a vein in the leg or an artery in the chest, thereby bypassing the obstruction and alleviating symptoms like angina or reducing the risk of heart attack.

This intervention is often recommended when there is extensive blockage in multiple arteries, or if the blockage is located in areas that are not amenable to other treatments, such as angioplasty or stenting. CABG has proven to improve outcomes in terms of survival and quality of life in patients with significant coronary artery disease.

In contrast, endarterectomy is generally used for carotid artery disease rather than coronary artery disease. Angioplasty, while a less invasive option for opening blocked arteries, may not be suitable for all patients, especially those with multiple blockages or complex coronary anatomy. Transcatheter aortic valve replacement focuses on treating valvular heart disease rather than direct coronary artery blockage, making it unrelated to the
