What is Transmyocardial Revascularization (TMR)?

TMR, is an innovative but clinically proven option for angina sufferers. It is a safe and effective treatment that reduces severe angina and improves the quality of life for patients with advanced coronary artery disease.

During the TMR, our surgeons will create tiny channels in the heart muscle with a laser. Placed about one-half inch apart, the channels are typically one millimeter in diameter, about the size of a standard sewing needle.

The surgeon will then determine the number of channels needed and where they will be located based on the condition of your heart muscle.

Benefits of TMR

There is new hope for you if you are living with coronary heart disease and suffer from severe angina. TMR provides a viable treatment option and these benefits:

  • Significantly decreased angina.
  • Pain relief for people who have coronary artery disease that cannot be treated with balloon angioplasty, coronary stenting or bypass surgery.
  • Reduced need for medications that are often prescribed to manage angina pain.
  • Improved quality of life and a return to a more active lifestyle.

How Effective is TMR?

The Food and Drug Administration (FDA) approved TMR as a safe and effective treatment for reducing severe angina in 1999. Since then, more than 30,000 TMR procedures have been performed nationwide.

Clinical studies published in The New England Journal of Medicine and the Annals of Thoracic Surgery demonstrated the following:

  • TMR is effective in improving the quality of life for more than 75 percent of patients who receive it.
  • An overwhelming majority of TMR patients continue to experience significantly reduced angina pain for five years after the treatment and longer.
  • TMR may also help patients live longer than if they had not had the procedure.
