Cardiac Surgical Procedures
Transmyocardial Revascularization
Transmyocardial
Revascularization (TMR) is a laser surgery that facilitates the growth
of blood vessels, resulting in decreased chest pain due to inadequate
oxygen supply reaching the heart muscle. TMR is usually performed in
conjunction with bypass surgery (CABG) on individuals with blood
deprived heart muscle. The surgeon may create 20-40 new channels, each
1 millimeter wide, in the muscular wall of the left ventricle using a
laser. These new channels stimulate angiogenesis, which is the natural
growth of new blood vessels within the heart muscle.
The
surgery is performed in the cardiac surgery suite under general
anesthesia and usually takes one to two hours to perform if this is the
sole procedure being done. It may only take minutes if being performed
as part of a Coronary Artery Bypass Graft (CABG) procedure.
