Overview Coronary bypass surgery is a procedure that restores blood flow to your heart muscle by diverting the flow of blood around a section of a blocked artery in your heart. Coronary bypass surgery is a surgical procedure that diverts the flow of blood around a section of a blocked or partially blocked artery in your heart. By creating a new pathway to the heart, coronary bypass surgery improves blood flow to your heart muscle. During coronary bypass surgery, a healthy blood vessel is taken from your leg, arm or chest and connected to the other arteries in your heart so that blood bypasses the diseased or blocked area.

Coronary stent [edit on Wikidata] A coronary stent is a tube-shaped device placed in the coronary arteries that supply blood to the heart, to keep the arteries open in the treatment of coronary heart disease. It is used in a procedure called percutaneous coronary intervention (PCI). Stents reduce chest pain and have been shown to improve survivability in the event of an acute myocardial infarction. Similar stents and procedures are used in non-coronary vessels e.g. in the legs in peripheral artery disease.

coronary But coronary also refers specifically to the arteries that surround and feed the heart. Coronary artery disease, or occlusion of the coronary arteries, can cause a heart attack, the death of heart tissue, or cardiac arrest, the failure of the heart to function.

Coronary Artery Disease (CAD) Percutaneous (per-ku-TA-ne-us) coronary intervention (PCI), commonly known as coronary angioplasty (AN-jee-oh-plas-tee) or simply angioplasty, is a non-surgical procedure used to open narrow or blocked coronary (heart) arteries.

The heart and the coronary arteries Coronary arteries are blood vessels that provide oxygen-rich blood and other nutrients to the heart muscle. The coronary arteries attach to and wrap around the heart 's surface. The left coronary artery branches off into smaller arteries.The most prominent ones are the:1  Left anterior descending artery, which supplies blood to the front of the heart. 2  Left circumflex artery, which encircles the heart muscle, supplying blood to the back of the heart.he left coronary artery branches off into smaller arteries.

Medical Definition of Coronary arteries Coronary arteries: The vessels that supply the heart muscle with blood rich in oxygen. They are called the coronary arteries because they encircle the heart in the manner of a crown. The word coronary comes from the Latin corona and Greek koron meaning crown. Like other arteries, the coronaries may be subject to arteriosclerosis (hardening of the arteries). There are a number of coronary arteries.

- Coronary circulation is the circulation of blood in the blood vessels of the heart muscle (myocardium). The vessels that deliver oxygen-rich blood to the myocardium are known as coronary arteries. The vessels that remove the deoxygenated blood from the heart muscle are known as cardiac veins.

Coronary Arteries and Heart Disease Arteries are vessels that carry blood away from the heart. The coronary arteries are the first blood vessels that branch off from the ascending aorta. The aorta is the largest artery in the body. It transports and distributes oxygen rich blood to all arteries.

Heart Disease Coronary heart disease is a chronic (long-term, ongoing), relentlessly progressive disease. Reducing risk factors may only slow its pace. Even angioplasty or bypass surgery only reduces the severity of the symptoms.

Coronary artery bypass surgery Coronary artery bypass surgery, also known as coronary artery bypass graft (CABG, pronounced cabbage) surgery, and colloquially heart bypass or bypass surgery, is a surgical procedure to restore normal blood flow to an obstructed coronary artery. There are two main approaches.

- Coronary heart disease—often simply called heart disease—is the main form of heart disease. It is a disorder of the blood vessels of the heart that can lead to heart attack. A heart attack happens when an artery becomes blocked, preventing oxygen and nutrients from getting to the heart.

Acute Coronary Syndrome - Topic Overview What is acute coronary syndrome? Acute coronary syndrome happens when the heart is not getting enough blood. It is an emergency. It includes unstable angina and heart attack. The coronary arteries supply oxygen-rich blood to the heart muscle. If these arteries are narrowed or blocked, the heart does not get enough oxygen.

- Coronary artery disease (CAD) is a narrowing of the coronary arteries that supply blood and oxygen to the heart. CAD is usually caused by a process called atherosclerosis. Atherosclerosis means that fat, cholesterol, and other substances have built up in the coronary arteries.

Coronary angioplasty and stents Coronary angioplasty (AN-jee-o-plas-tee), also called percutaneous coronary intervention, is a procedure used to open clogged heart arteries. Angioplasty involves temporarily inserting and inflating a tiny balloon where your artery is clogged to help widen the artery.

Heart disease guide Angioplasty and stents. A coronary angioplasty is a procedure to treat heart disease by widening narrowed or blocked arteries, then keeping them open with a special tube of wire mesh called a stent. The procedure is also known as percutaneous transluminal coronary angioplasty, PTCA, or percutaneous coronary intervention or PCI.

Coronary Artery Disease Coronary artery disease (CAD) is the most common type of heart disease. It is the leading cause of death in the United States in both men and women. CAD happens when the arteries that supply blood to heart muscle become hardened and narrowed. This is due to the buildup of cholesterol and other material, called plaque, on their inner walls. This buildup is called atherosclerosis. As it grows, less blood can flow through the arteries.

Percutaneous coronary intervention The coronary guidewire, which is an extremely thin wire with a radio-opaque flexible tip, is inserted through the guiding catheter and into the coronary artery. While visualizing again by real-time X-ray imaging, the cardiologist guides the wire through the coronary artery to the site of the stenosis or blockage.
