Transmyocardial revascularization, abbreviated as TMR, may be a suitable treatment option for patients with coronary artery disease that has not responded to other treatment or cannot withstand other surgical treatments.  When done as a primary surgery,TMR is a minimally invasive procedure, performed through two small incisions in the side and chest. Though it sometimes is a secondary surgery and can accompany open surgery, such as coronary artery bypass surgery.

This procedure employs a Holmium laser or a carbon dioxide, CO2, laser. This laser carefully creates a series of 20-50 passages the size of a pin’s head in a specific region of the heart, typically the left ventricle. The outside of these passages seals over almost immediately, but the passages inside the heart muscle remain and work to increase blood flow to the heart. These channels in the ventricle improve blood flow by allowing blood into the heart muscle as it contracts and encourages the growth of new capillaries to supply blood to the heart.

Transmyocardial revascularization may not be right for everyone. The cardiac surgeons at Cardiac Surgery Associates of Tampa can review your symptoms and history of care to best determine if TMR would be effective for you. If you have questions about the TMR procedure, please contact our office online or by phone at 813.910.0027.
