Cutting balloon angioplasty through stent struts of a jailed sidebranch ostial lesion

The treatment of sidebranch ostial lesions jailed after stent implantation is challenging. We report a case of successful Cutting Balloon angioplasty through stent struts of a severe, elastic sidebranch ostial lesion. Three-day follow-up angiography showed no recurrent stenosis. The patient was discharged with complete resolution of chest discomfort and the post-hospitalization course was uneventful. Cutting Balloon angioplasty may be an optimal strategy for the treatment of elastic ostial lesions in smaller vessels that are suboptimal for stenting. The long-term benefits of using a Cutting Balloon for the treatment of sidebranch ostial lesions are still to be determined.
