What is the main purpose of trans myocardial revascularization (TMR)?

Trans myocardial revascularization (TMR) is primarily employed in situations where traditional surgical interventions, such as stenting or bypass grafts, are not viable options for patients with severe coronary artery disease. Inoperable targets for stenting or bypass grafts often arise due to complex coronary pathology or significant comorbidities that complicate standard surgical approaches. TMR aims to alleviate symptoms of angina and improve blood flow to the ischemic myocardium by creating small channels in the heart muscle, thus providing an alternative route for blood flow to areas that are normally deprived of adequate perfusion.

This technique is particularly beneficial for individuals who have limited treatment options due to either the configuration of their coronary arteries or their overall health status, making it a targeted therapy for those who cannot undergo conventional surgical revascularization. By enhancing blood flow in this manner, TMR can help improve cardiac function and quality of life for those patients considered unsuitable for more invasive interventions.
