Excimer laser coronary atherectomy for a severe calcified coronary ostium lesion: A case report

BACKGROUND Percutaneous coronary intervention can be challenging for ostial coronary artery lesions due to calcium burden and elastic fiber content. Excimer laser coronary a therectomv (ELCA) is a less common treatment for severe calcified coronary ostium lesions. CASE SUMMARY An 81 -year -old male presented to the Cardiology Department of Qingdao Municipal Hospital with a 1 -year history of chest pain. Coronary angiography showed severe calcific stenosis (approximately 90%) in the right coronary artery ostium. The right coronary artery ostiurn was unable to he advanced using a 2.5 mm x 12.0 mm balloon (NC Sprinter, Medtronic, United States) or dilated using a 2.0 mm x 12.0 mm balloon (Sprinter, Medtronic, United States). The patient underwent successful ELCA and balloon dilation of the calcified coronary ostium lesion. CONCLUSION ELCA appears to be a safe and effective treatment for the management of severe calcified coronary ostium lesions.
