Procedural steps in DCB group. (A) Wiring both branches; (B) MV lesion preparation; (C) MV stent implantation; (D) rewire SB from the distal strut; (E) SB lesion preparation: plaque modification and expand the orifice of SB; (F) SB DCB angioplasty; (G) final kissing inflation; (H) POT if necessary; (I) final result I; (J) dissection (≥type C or flow-limited, white arrow); (K) bailout stent deployment (black arrow, the distance between the proximal end of the stent and the ostium of the vessel ≥ 3 mm) and final result II. MV, denotes main vessel; NC, non-compliant; SB, side branch; DCB, drug-coated balloon; POT, proximal optimizing technique. If there was a residual stenosis ≤ 30% only in proximal 5 mm regardless of other segment after SB lesion preparation, a DCB + DES strategy was initially selected. DCB angioplasty was done first, followed by stent deployment to ensure complete coverage of the dissection and severe elastic recoil segment (residual stenosis > 30%). The distance between the proximal end of the stent and the ostium of SB ≥ 3 mm.
