Commissurotomy
Commissurotomy The heart valves are made up of leaflets. The leaflets touch each other and the edge of the area where they come in contact is known as the commissures. In some patients, specifically those with rheumatic heart disease, the commissures can become scarred and fail to open and allow blood to flow through easily. In situations like this, the commissures can be released or reopened with a procedure known as commissurotomy.

PREVIOUS AND NEXT TERMS--------------------------------------
Clubbing
The ends of the fingers and toes enlarge and bend inward; related to inadequate oxygen-rich blood supply. Often seen with congenital heart defects, but also seen in other conditions.
CPR (cardiopulmonary resuscitation)
A procedure using cardiac and respiratory equipment and medications possibly to restore the heartbeat and/or breathing.
Coagulation Problems
Problem with blood clotting, either too much clotting or not enough.
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.
Collateral Blood Vessels
Small capillary-like branches of the 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
Complete Heart Block (heart block)
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.
Complex Carbohydrates
Starchy foods that are good sources of energy and nutrients, such as bread, rice, pasta and grains.
Congestive Heart Failure (CHF or heart failure)
A condition where the heart muscle weakens and can not pump blood efficiently throughout the body.
Connective Tissue Disease
Disease caused by problem with collagen (the elastic support system in the body); can have a vascular component. Examples include Systemic Lupus Erythematosus (SLE), rheumatoid arthritis (RA). Can also be referred to mixed connective tissue diseases (MCTD)
Constrictive Pericarditis
The pericardium is the sac around the heart. In some patients, this sac can become inflamed and scarred. If this scarring process produces a contracture or shrinkage of the pericardium, it can prevent the heart from filling to its full extent. This disease is known as constrictive pericarditis.
