Laser Treatment Provides Sustained Angina Relief

A long-term study has shown that a procedure known as transmyocardial revascularization (TMR) with a carbon dioxide (CO2) laser can produce angina relief that is sustained for more than five years. The findings are to be presented at the 73rd Scientific Sessions of the American Heart Association in New Orleans (LA, USA) in November.

Working with researchers and heart surgery centers around the world, the TMR device was developed by PLC Systems Inc. (Franklin, MA, USA) and called The Heart Laser System. The system has been cleared by the U.S. Food and Drug Administration (FDA) for treatment of areas of the heart not amenable to direct revascularization.

The data that will be presented will definitely show that angina relief demonstrated at one year follow-up is maintained for more than five years, said Dr. Keith Horvath, assistant professor of surgery at Northwestern University Medical School (Chicago, IL, USA), who will make the presentation.
