Name of Procedure or Surgery	What the Procedure Does	Reason for Procedure
Angioplasty (Also known as Percutaneous Transluminal Coronary Angioplasty [PTCA], Percutaneous Coronary Interventions [PCI], Balloon Angioplasty and Coronary Artery Balloon Dilation)	Tiny balloons are threaded through a blood vessel and into a coronary artery to widen blocked areas where blood flow to the heart has been reduced or cut off. Often combined with implantation of a stent to help prop the artery open and decrease the chance of another blockage. Considered less invasive because the body is not cut open. Lasts from 30 minutes to several hours. Often requires an overnight hospital stay.	Greatly increases blood flow through the blocked artery. Decreases chest pain (angina). Increases ability for physical activity. Reduces risk of a heart attack. Can also be used to open neck and brain arteries to help prevent stroke.
Laser Angioplasty	Similar to angioplasty except that the catheter has a laser tip that opens the blocked artery. Pulsating beams of light vaporize the plaque buildup.	Increases blood flow through blocked arteries.
Atherectomy	Similar to angioplasty except that the catheter has a rotating shaver on its tip to cut away plaque from the artery.	Increases blood flow through the blocked artery by removing plaque buildup. May also be used in carotid arteries (major arteries of the neck leading to the brain) to remove plaque and reduce risk for stroke.
Stent Procedure	A stent is a wire mesh tube used to prop open an artery during angioplasty. The stent stays in the artery permanently.	Holds the artery open. Improves blood flow to the heart muscle. Relieves chest pain (angina).
Transmyocardial Revascularization (TMR)	An incision is made on the left breast to expose the heart. Then, a laser is used to drill a series of holes from the outside of the heart into the heart's pumping chamber. In some patients TMR is combined with bypass surgery. In those cases an incision through the breastbone is used for the bypass. Usually requires a hospital stay.	Used to relieve severe chest pain (angina) in very ill patients who aren’t candidates for bypass surgery or angioplasty.
Bypass Surgery (Also known as CABG or “cabbage”, Coronary Artery Bypass Graft and Open-heart Surgery)	Treats blocked heart arteries by creating new passages for blood to flow to your heart muscle. It works by taking arteries or veins from other parts of your body – called grafts – and using them to reroute the blood around the clogged artery. A patient may undergo one, two, three or more bypass grafts, depending on how many coronary arteries are blocked. Requires several days in the hospital.	One of the most common and effective procedures to manage blockage of blood to the heart muscle. Improves the supply of blood and oxygen to the heart. Relieves chest pain (angina). Reduces risk of heart attack. Improves ability for physical activity.
Minimally Invasive Heart Surgery (Also known as Limited Access Coronary Artery Surgery and includes Port-Access Coronary Artery Bypass [PACAB or PortCAB] and Minimally Invasive Coronary Artery Bypass Graft [MIDCAB])	An alternative to standard bypass surgery (CABG). Small incisions ("ports") are made in the chest. Chest arteries or veins from your leg are attached to the heart to "bypass" the clogged coronary artery or arteries. The instruments are passed through the ports to perform the bypasses. The surgeon views these operations on video monitors rather than directly. In PACAB, the heart is stopped and blood is pumped through an oxygenator or "heart-lung" machine. MIDCAB is used to avoid the heart-lung machine. It's done while the heart is still beating. Requires several days in the hospital.	Preferred treatment for many types of rapid heartbeats (arrhythmias) especially supraventricular tachyarrhythmias.
Radiofrequency Ablation (Also known as Catheter Ablation)	A catheter with an electrode at its tip is guided through the veins to the heart muscle with real-time, moving X-rays (fluoroscopy) displayed on a video screen. The catheter is placed at the exact site inside the heart where cells give off the electrical signals that stimulate the abnormal heart rhythm. Then a mild, painless radiofrequency energy (similar to microwave heat) is transmitted to the pathway. This destroys carefully selected heart muscle cells in a very small area (about 1/5 of an inch).	Preferred treatment for many types of rapid heartbeats (arrhythmias) especially supraventricular tachyarrhythmias.
Artificial Heart Valve Surgery (Also known as Heart Valve Replacement Surgery)	Replaces an abnormal or diseased heart valve with a healthy one.	Restores function of the heart valves.
Heart Transplant	Removes a diseased heart and replaces it with a healthy human heart when a heart is irreversibly damaged. Uses hearts from organ donation.	Recognized as a proven procedure to restore heart health in appropriately selected patients.
Cardiomyoplasty	An experimental procedure in which skeletal muscles are taken from a patient's back or abdomen. Then they're wrapped around an ailing heart. This added muscle, aided by ongoing stimulation from a device similar to a pacemaker, may boost the heart's pumping motion.	Increases the pumping motion of the heart.
