Intravascular Lithotripsy for the Treatment of Stent Underexpansion: the Multicenter IVL-DRAGON Registry

The IVL-Dragon Registry was a multicenter study that enrolled consecutive patients with stent underexpansion treated with IVL in high-volume PCI centers. The primary efficacy endpoint was clinical success, defined as a reduction of stent underexpansion to <30% with no evidence of in-hospital device-oriented composite end point (DOCE) (defined as a composite of cardiac death, target lesion revascularization, and target vessel myocardial infarction).
