Transmyocardial laser revascularization creates channels in the heart muscle for patients with severe angina. This procedure is typically for those ineligible for angioplasty or bypass grafting.

Area of Science:

  • Cardiovascular Surgery
  • Minimally Invasive Cardiac Procedures
  • Interventional Cardiology

Background:

  • Transmyocardial laser revascularization (TMLR) is a surgical procedure.
  • It involves creating channels between the left ventricular cavity and the myocardium.
  • TMLR is often performed for patients with refractory angina pectoris.

Purpose of the Study:

  • To describe the procedure of transmyocardial laser revascularization.
  • To outline the common indications for TMLR.
  • To discuss its application in patients unsuitable for conventional revascularization.

Main Methods:

  • Surgical creation of myocardial channels using a laser.
  • Procedure typically performed via left thoracotomy.

  • Can be performed as a standalone procedure or combined with coronary artery bypass grafting (CABG).
  • Often performed without cardiopulmonary bypass.

    • Main Results:

    • Channels are created connecting the left ventricular cavity to the myocardium.
    • The procedure aims to improve myocardial perfusion.
    • Effective in managing angina pectoris in select patient populations.

    Conclusions:

    • Transmyocardial laser revascularization is a viable option for angina.
    • It is indicated for patients with coronary anatomy unsuitable for angioplasty or bypass grafting.
    • Offers an alternative revascularization strategy for refractory ischemic heart disease.
