  29. Evidence of aneurysm in target vessel within 10 mm of the target lesion
  30. Target lesion is an ostial location (LAD, LCX, or RCA, within 5 mm of ostium) or an unprotected left main lesion.
  31. Target lesion is a bifurcation with ostial diameter stenosis ≥30%
  32. Second lesion with >50% stenosis in the same target vessel as the target lesion including its side branches
  33. Target lesion is located in a native vessel that can only be reached by going through a saphenous vein or arterial bypass graft
  34. Other situations not suitable for enrollment assessed by investigators.
