경피적 관상동맥 중재시술에서 Cutting Balloon의 유용성 = Clinical Utility of Cutting Balloon

다국어 초록 (Multilingual Abstract)

The cutting balloon potentially useful in percutaneous coronary interventions to reduce vessel injury and restenosis. In de novo lesions, the largest randomized trial to date has not been improved efficacy over conventional balloons. At present, the most persuasive evidence exists in small vessels<3.0 mm, with favorable immediate and long-term results. The cutting balloon is currently used most often for the treatment of in-stent restenosis: however, its effectiveness versus other alternatives still under investigation. The stability of the cutting balloon at the treatment site makes the device an attractive pre-intervention modality for radiation therapy. Determining whether the cutting balloon has advantage over other modalities in combination with radiation therapy is the subjects of ongoing investigation.
