Transmyocardial Revascularization (TMR)

What is Transmyocardial Revascularization?


Cross-section of the heart with TMR procedure.

Trans Myocardial Revascularization is a treatment modality available for advanced coronary artery disease. TMR is a surgical procedure that uses a laser to create 20-45 1mm "channels" into the heart muscle. TMR can be used alone or in conjunction with CABG for complete revascularization, which is the aim in most CABG operations. TMR alone is generally reserved for severe diffuse disease not amendable to other forms of therapy. TMR by the Eclipse and Heart Laser systems is approved by the Federal Drug & Food Authority (FDA) in the USA. The TMR machines used in Penang, (at the General Hospital & Penang Adventist Hospital) are FDA approved. A non-operative catheter technique of doing TMR is currently being evaluated in several countries.

In clinical studies, TMR has been shown to:

  • reduce angina symptoms
  • increase exercise tolerance
  • reduce medication needs
  • reduce re-hospitalizations
  • increase event-free survival
  • improve patients' quality of life

Are You a Candidate for TMR?

You may be a candidate for the TMR procedure if:

  • you have angina due to advanced cardiovascular disease
  • (your physician believes that) you are not a candidate for standard therapy
  • the heart muscle around these affected blood vessels is healthy
  • your angina cannot be managed with medications or these medications are causing serious side effects

Are There Risks Associated With TMR?

TMR requires a surgical procedure and there are risks associated with any surgery in general and with the TMR procedure itself. Your doctor will discuss all the risks and benefits of surgery and the TMR procedure with you.

What Follow-up Will You Receive?

Your follow-up requirements for recovery after a TMR procedure are similar to those following other heart surgeries. You will undergo regular check-ups by your physician. Your physician will advise you when you may return to more normal activities.
