Laser atherectomy for coronary artery disease.

Efficacy and safety for thrombotic lesions enrolling 328 patients at six centers in naniwa japan of which 5 5 had ctos achieved a high success rate of 92 5. Wavelength determines absorbed scattered energy and penetration depth and longer wavelengths generally have weaker absorption. 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. Today laser atherectomy is more frequently used in peripheral arterial disease than in coronary disease.

If you have peripheral artery disease p a d in your legs peripheral laser atherectomy is just one procedure your physician might recommend. 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. 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. Peripheral laser atherectomy uses a catheter that emits high energy light laser to unblock the artery.

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. We identified 58 cases of balloon failure treated with elca rotational atherectomy ra over four. One patient died from coronary perforation directly related to elca.
