Heart Disease Terms
Coarctation of the Aorta: A severe narrowing of the aorta, causing a decrease in blood flow to the lower part of the body. This narrowing is a congenital defect and can be corrected with surgery or balloon angioplasty.
Collateral Blood Vessels: Small capillary-like branches of an artery that form over time in response to narrowed coronary arteries. The collaterals "bypass" the area of narrowing and help to restore blood flow. However, during times of increased exertion, the collaterals may not be able to supply enough oxygen-rich blood to the heart muscle.
Commissurotomy: A surgical procedure that helps to repair the damage caused by defective heart valves. In some patients, specifically those with rheumatic heart disease, this area of the heart (also called the commissures) can become scarred and the valve leaflets fail to open and allow blood to flow through easily. In this surgery, the commissures can be released or reopened.
Complex Carbohydrates: Starchy foods that are good sources of energy and nutrients, such as whole grain breads, rice, and pasta.
Congenital Heart Defects: Heart defects present at birth.
Congestive Heart Failure (CHF or heart failure): A condition where the heart muscle weakens and can't pump blood efficiently throughout the body.
Constrictive Pericarditis: The pericardium is the sac around the heart. In people with constrictive pericarditis, this sac becomes inflamed and scarred leading to shrinkage of the pericardium. This can prevent the heart from filling to its full extent.
Coronary Arteries: Network of blood vessels that branch off the aorta to supply the heart muscle with oxygen-rich blood. There are two main coronary arteries: the right and the left. The left splits into two arteries called the circumflex and the left anterior descending (LAD) arteries, thus, the heart is often considered to have three major coronary arteries.
Coronary Artery Disease (atherosclerosis): A build-up of fatty material in the wall of the coronary artery that causes significant narrowing of the artery.
Coronary Spasm: Repeated contractions and dilations of the coronary arteries, causing a lack of blood supply to the heart muscle. It may occur at rest and can even occur in people without significant coronary artery disease.
