Question

Quizplus · Accepted Answer

The operation that is typically performed when blockages in coronary arteries are too severe for percutaneous procedures (such as angioplasty or stenting) is a coronary artery bypass graft (CABG) surgery. CABG involves taking a healthy blood vessel from another part of the body (such as the chest or leg) and using it to bypass the blocked portion of the coronary artery, allowing blood to flow freely to the heart muscle. Aortography is a diagnostic procedure that involves injecting dye into the aorta to visualize blockages or abnormalities, while atherectomy is a technique that uses a catheter to physically remove plaque buildup from inside an artery. Cardiopulmonary resuscitation (CPR) is a life-saving procedure used to restart the heart in cases of cardiac arrest, and would not be used for treatment of severe coronary artery disease.
