Transmyocardial Revascularization (TMR)

What the Procedure Does

An incision is made on the left breast to expose the heart. Then, a laser is used to drill a series of holes from the outside of the heart into the heart’s pumping chamber. In some patients TMR is combined with bypass surgery. In those cases an incision through the breastbone is used for the bypass. Usually requires a hospital stay.

Reason for the Procedure

  • Used to relieve severe chest pain (angina) in very ill patients who aren’t candidates for bypass surgery or angioplasty.
