A special catheter, with an acorn-shaped diamond-coated tip, is guided to the point of narrowing in the coronary artery. The tip spins around at a high speed and grinds away the plaque on the artery walls. The microscopic particles are washed safely away in your blood stream and filtered out by the liver and spleen. This process is repeated as needed to allow better blood flow.
Industry:Health care
A treatment for those with symptomatic coronary artery disease (also called refractory angina), who are not eligible for standard treatments of revascularization (such as heart bypass surgery. ) During EECP, cuffs wrapped around the calves, thighs, and buttocks are inflated and deflated, gently but firmly compressing the blood vessels in the lower limbs, increasing blood flow to the heart. EECP may stimulate the openings or formation of collateral vessels to create a "natural bypass" around narrowed or blocked arteries.

A small monitor is attached to electrode leads (usually on your finger or wrist). Your heart's rhythm is transmitted over the phone line with the aid of this device to your doctor's office.
Industry:Health care
A narrowing of the flow of blood below the aortic valve in the left ventricle. It is usually caused by a membrane or thickening in the muscle in this area.
Industry:Health care
An arrhythmia. The electrical current is slowed between the atria and ventricles. In more severe cases, conduction is blocked completely and the atria and ventricles beat independently.
Industry:Health care
A procedure that involves infusing a medication (dobutamine) through an intravenous (IV) line while you are closely monitored. This drug stimulates your heart allowing evaluation of heart and valve function at rest and with exertion, when you are unable to exercise on a treadmill or stationary cycle.
Industry:Health care
An invasive imaging procedure that creates a picture of the heart's movement, valves, and chambers using high frequency sound waves that come from a small transducer passed down your throat. TEE provides clear images of the heart's movement because the transducer is close to the heart and limits interference from air in the lungs. Echo is often combined with Doppler ultrasound and color Doppler to evaluate blood flow across the heart's valves.
Industry:Health care
A build-up of fatty material in the wall of the coronary artery that causes narrowing of the artery.
Industry:Health care
A sudden loss of brain function due to decreased blood flow to an area of the brain.
Industry:Health care
A destructive fragment of oxygen produced as a by-product. Increased free radicals are thought to trigger atherosclerosis.
