Surgical and Other Procedures for Coronary Artery Disease (CAD)
by Michelle Badash, MS
Surgical and other procedures may be used to treat severe CAD and CAD that is causing angina when other treatment methods fail.
Coronary Artery Bypass Graft (CABG)
CABG is more commonly known as open-heart or bypass surgery. It is the most common type of heart surgery in the US.
During this operation, a healthy blood vessel is removed from the leg or another area of the body. The healthy blood vessel is connected to the damaged artery just above and just below the blocked or partially blocked area. This allows some blood to bypass the damaged area by moving through the new blood vessel. If more than one area is blocked, a bypass can be done for each area (referred to as a double, triple, or quadruple bypass).
Types of CABG include:
Talk to your doctor about which option is better for you. Although CABG may relieve symptoms, it does not cure heart disease. You still must maintain a healthy lifestyle that includes achieving a healthy weight, eating a heart healthy diet, not smoking, and taking medications.
Transmyocardial Laser Revascularization (TMR)
TMR is generally used in people who have inoperable CAD with severe angina. A laser is used through small incisions on the left side of the chest to create small channels in the affected part of the heart. These channels improve blood flow to the heart muscle. TMR can be done with or without CABG. A computer is used to pulse the laser at a specific time in the least active part of the heart beat cycle.
