Transmyocardial Revascularization (TMR)

Transmyocardial revascularization (TMR) is a highly specialized procedure to treat patients with severe coronary artery disease and angina who cannot undergo standard coronary artery bypass grafting. It uses a laser to make channels, or small holes, directly into the heart muscle.


How does it work?

During the procedure, a Deborah® physician creates channels through the heart muscle using a laser. As the channels heal, they stimulate the creation of new small vessels or capillaries. This process is called angiogenesis. Over the next few weeks or months, the patient’s angina will improve or disappear.


Am I a good candidate for treatment?

Patients who meet the following criteria may be good candidates for TMR:

  • Have angina due to advanced cardiovascular disease
  • Not a candidate for traditional surgery
  • Heart muscle around these affected blood vessels is healthy
  • Angina is not managed with medication

What can I expect after treatment?

Most of the time, the symptoms of coronary artery disease and angina get better after TMR, but it may take a few months to see improvement.

Patients find that after TMR they can now do all of the activities that once caused them pain. They may also find that they do not need to take as many heart medicines.

Studies have shown that one year after surgery, 80% to 90% of patients treated with TMR still feel better than they did before they had the surgery. They also have a lower risk of heart attack.
