A hearty solution
Transmyocardial laser revascularisation (TMR), a new technique for creating channels in the left ventricular wall to improve blood supply to the damaged heart muscle, offers new hope to those suffering from heart disease. Heart patients who are unfit to undergo a coronary artery bypass graft or percutaneous transluminal coronary angioplasty, can benefit from TMR, which uses high-power CO 2 laser. PLC systems of Cambridge, Massachusetts, US, which has already carried out encouraging tests on over 200 patients with endstage coronary artery disease, is expecting the US Food and Drug Administration's approval to start marketing the laser device.
