• Abstract:

  Laser device emits laser by optical

  amplification which is based on simulated

  emission of electromagnetic radiation. Earlier a

  CO2 laser with 450W power was used for the

  creation of channels in heart vessels. Currently

  CO2 laser having wavelength of 10,600 nm with

  energy level of 15-20 joules per pulse and pulse

  duration of 25-40ms are being used. TMLR is

  a technique in which small 20-30 channels of

  size 1mm are drilled in left ventricle and heart

  muscle by CO2 gas laser for better perfusion

  of blood. Laser is applied on heart vessels by

  a device named laser gun. Trans-myocardial

  revascularization by CO2 laser is a revolution

  in cardiology. It is an alternative to open heart

  surgery, applied on the patients of refractory

  angina who are not able to be treated by

  conventional methods.
