Surgical and other procedures may be used to treat severe CAD and CAD that is causing angina when other treatment methods fail.
is more commonly known as open-heart or bypass surgery. It is the most common type of heart surgery in the United States.
During this operation, a blood vessel is taken from the leg or another area of the body and grafted into a diseased artery, bypassing the blocked area. If more than one area is blocked, a bypass can be done for each area (referred to as a double, triple, or quadruple bypass). The blood can then go around the obstruction to supply the heart with enough oxygen-rich blood.
Types of CABG include:
Results from several studies indicate that traditional and off-pump CABG have similar short- and long-term results. Talk to your doctor about which option is better for you. Although CABG may relieve symtoms, 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.
Keyhole incisions are made along the left side of the chest and between the ribs to access front-facing blood vessels. It is a fairly new off-pump procedure that may not be an option for everyone or widely available.
TMR is generally used in people who have inoperable CAD with severe angina. A laser is used through keyhole 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 during a specific time in the least active part of the heart beat cycle.
Other procedures are used to open blocked arteries include:
Cardiac procedures and surgeries.
