The stent is placed in the main branch (MB) covering the side branch (SB) after directional coronary atherectomy (DCA) debulking. It was followed by kissing balloon technique (KBT) or balloon angioplasty (BA) for the SB when necessary. (B) Noncrossover stenting. Plaque debulking by DCA is performed in the MB. The stent is then placed in the MB ostium without covering the SB.
