Laser atherectomy for coronary artery disease.

We identified 58 cases of balloon failure treated with elca rotational atherectomy ra over four. 17 bader et al. Today laser atherectomy is more frequently used in peripheral arterial disease than in coronary disease. 4 absorption depth is a critical component of atherectomy because the interaction between tissue type and wavelength varies and the potential for perforation or dissection exists.

Wavelength determines absorbed scattered energy and penetration depth and longer wavelengths generally have weaker absorption. Once the tube reaches the narrowed portion of the artery a cutting device whirling blade such as rotational atherectomy or a laser beam can be used to remove the. During the procedure a thin flexible tube a catheter is inserted through an artery in the groin or arm and carefully guided into the coronary artery that is narrowed.

At one point laser atherectomy was quite popular in vein graft disease and bifurcations but over a period of years its use in the coronary arterial tree has substantially decreased. One patient died from coronary perforation directly related to elca. To establish success and complication rates of excimer laser coronary atherectomy elca in a contemporary series of patients with balloon failure during percutaneous coronary intervention pci of both chronic total occlusions cto and lesions with distal timi 3 flow.
