Transmyocardial revascularization
Transmyocardial Revascularization
Transmyocardial revascularization (pronunciation: trans-my-o-car-dee-al re-vas-cu-lar-iz-a-tion) is a surgical procedure used to treat angina in patients with severe coronary artery disease who are not candidates for coronary artery bypass grafting or percutaneous coronary intervention.
Etymology
The term "transmyocardial revascularization" is derived from the Latin trans meaning "across", myo meaning "muscle", cardium meaning "heart", and revascularization meaning "restoration of blood supply".
Procedure
During transmyocardial revascularization, a surgeon uses a laser to create small channels in the heart muscle. These channels improve blood flow to the heart muscle by allowing oxygen-rich blood from the heart's main chamber to flow directly into the heart muscle.
