摘　　要：To the Editor： A 73-year-old female was referred to our hospital for evaluation of unstable angina pectoris. She had a greater than 10-year history of hypertension. Coronary angiography （CAG） was performed in another hospital in March 2017, which showed diffuse calcific stenosis （about 90%） in the proximal and mid-left anterior descending （LAD） artery, 70% stenosis in the ostial obtuse marginal branch, and no apparent stenosis in the right coronary artery. The lesion in the LAD could not be intervened because the 2.0 mm×15.0 mm Sprinter balloon （Medtronic, USA） could not be expanded and the 2.5 mm×15.0 mm NC Sprinter balloon （Medtronic, USA） could not pass through the lesion.To the Editor： A 73-year-old female was referred to our hospital for evaluation of unstable angina pectoris.
