Thoracoscopic surgery is a procedure that is done to see inside the
chest cavity and make surgical repairs. It is a less invasive surgical
technique than open-chest surgery or other similar procedures.
The surgeon makes one or more small incisions in the chest area and
places a special camera, called a thorascope, to see the area around the heart.
Guided by this camera, the surgeon inserts one or more surgical instruments
through the incisions and makes repairs where needed.
Mitral valve prolapse is a common cause of a heart murmur caused by a "leaky" heart valve. Most cases of mitral valve prolapse are not serious and only need to be monitored.
Mitral valve prolapse is associated with many other symptoms and conditions. But experts aren't sure that mitral valve prolapse is what causes them.
