TMR Laser (Transmyocardial Revascularization)
| Transmyocardial revascularization (TMR) is an advanced surgical procedure designed to help increase blood flow in damaged areas of the heart. |
The TMR laser is a new surgical tool that is used alone or in addition to bypass surgery in order to alleviate chest pain. The technique uses a laser to create tiny channels in the heart muscle that revascularize, or increase blood flow, to the damaged area of the heart.
Typically, when blood supply is restricted in an area of the heart, a heart attack or other serious consequences may result. The channels created by TMR laser provide a new route for blood to reach the affected area of the heart muscle.
