Comparison of Intravascular Coronary Lithotripsy and Excimer Laser Coronary Atherectomy for Severe Stent Underexpansion: the Multicenter IVL- ELCA DRAGON Registry

The IVL- ELCA DRAGON Registry is a multicenter study that enrolled consecutive patients with stent underexpansion treated with IVL ora ELCA in high-volume PCI centers.

The primary efficacy endpoint was device success (technical success with a final stent expansion ≥ 80%). Thirty days device-oriented composite endpoint (DOCE: cardiac death, target lesion revascularization, or target vessel myocardial infarction) was the secondary endpoint.
