  • Device success is defined as the attainment at the target site of a final residual diameter stenosis of <50% with only the assigned study device.

  • Lesion success is defined as the attainment at the target site of a final residual diameter stenosis of <50% with any percutaneous method.

  • Procedure success is defined as the attainment at the target site of a final residual diameter stenosis of <50%, together with the absence of any in-hospital major adverse cardiac events.  Abbreviations as in Table 1.
