Core Tip

Core Tip: In the presented case, coronary angiography showed severe calcific stenosis (approximately 90%) in the right coronary artery ostium. A 2.5 mm × 12.0 mm balloon was unable to be advanced into the lesion, while a 2.0 mm × 12.0 mm balloon could not be inflated in the right ostium. Intravascular ultrasonography revealed severe calcifications. The patient underwent an excimer laser coronary atherectomy (ELCA) and balloon dilation, and remained asymptomatic during the 12-mo follow-up. This is the first case report of the successful use of ELCA and small balloon dilatation in treating a severely calcified cardiac ostium lesion.
