Outcomes of paclitaxel‐coated balloon angioplasty for in‐stent calcified nodule: An optical coherence tomography study

Paclitaxel‐coated balloon (PCB) angioplasty emerges as an effective therapeutic option for in‐stent restenosis (ISR). However, whether PCB angioplasty would be effective for in‐stent calcified nodule (ISCN) lesions remain fully understood. This study aimed to evaluate the frequency and outcomes of ISCN in patients undergoing PCB angioplasty for ISR after second‐generation drug‐eluting stents (G2‐DES) implantation.
