Commissurotomy
Commissurotomy
Commissurotomy (pronounced: kuh-mish-uh-ROT-uh-mee) is a surgical procedure that is performed to treat certain types of heart valve disease.
Etymology
The term "commissurotomy" is derived from the Latin word "commissura," meaning "a joining," and the Greek word "tome," meaning "a cutting."
Definition
Commissurotomy is a surgical procedure that involves the separation of the fused commissures (the points of contact or fusion between the cusps of the heart valves) that have become stuck together due to disease. This procedure is typically performed to treat conditions such as mitral stenosis or aortic stenosis.
Procedure
During a commissurotomy, the surgeon makes an incision in the heart valve and carefully separates the fused commissures. This allows the valve to open and close more freely, improving blood flow through the heart.
Related Terms
- Mitral valve: One of the four valves in the heart, located between the left atrium and the left ventricle.
- Aortic valve: One of the four valves in the heart, located between the left ventricle and the aorta.
- Stenosis: A condition characterized by the narrowing of a blood vessel or valve in the heart.
- Commissure: The point of contact or fusion between two structures, such as the cusps of the heart valves.
Risks and Complications
As with any surgical procedure, commissurotomy carries certain risks and potential complications. These may include infection, bleeding, damage to the heart valve, and the need for further surgery or valve replacement.
