Transmyocardial Revascularization or TMR, is a surgical revascularization procedure that requires visualization of the heart. TMR may be performed either through a minimally invasive or an open surgical approach that is determined by the surgeon.

CO₂ TMR technology is a safe and effective angina relief therapy for use where the patient has diffuse coronary vessels with poor bypass graft targets. Because it is easily moved between surgical suites, the CO₂ Heart Laser 2 enables the surgeon to make timely operative decisions to revascularize the heart with CO₂ TMR.  A recent article in Cardiovascular Business describes the procedure and potential results.

The therapeutic advantages of TMR with the CO₂Heart Laser include:

• Significant reduction of angina pain
• Long-term pain relief
• Improved patient quality of life

On March 31, 2007, PLC Medical Systems announced it had signed an exclusive distribution agreement for its TMR products and services in the U.S. with Novadaq Corp., a wholly-owned U.S. subsidiary of Novadaq Technologies, Inc. (TSX: NDQ), a developer of medical imaging systems for the operating room. Read the press release.

Caution: US Federal Law restricts this device to sale by or on the order of a physician (or properly licensed practitioner). US Federal Law further restricts the use of this device to practitioners who have been trained in laser heart surgery including laser system calibration and operation.

In clinical studies, the risk of perioperative mortality is higher in patients with unstable angina.

Use of this device is restricted to patients who have signed a consent form to ensure that the risks associated with TMR have been fully explained and understood.
