Abstract: Objective:To evaluate both feasibility and safety of excimer laser coronary atherectomy (ELCA) in managing complicated coronary lesions.Methods:Two patients with complicated coronary lesions, which could not be treated by balloon, underwent ELCA.Two technical parameters were selected with 40-60mJ/mm2, 30-40 pulses/s of frequency.The coronary plaque was treated 2-4 times by ELCA, which took no more than 10 minutes.Results:With the ELCA catheter gone through both lesions, the balloons dilated completely and stents implanted, both patients achieved the revascularization without any complications.Conclusions:ELCA is easy to operate with good effect, which can be a new choice for patients with complicated coronary lesions.
