Presentation transcript:

OCT Characterization of Calcified Lesions and the Effects of Lithoplasty and Stenting (A) Optimal coherence tomography (OCT) cross sections acquired before lithoplasty in 3 different segments of a calcified lesion treated with lithoplasty. (B) Post-lithoplasty, there were multiple fractures noted in the same frames (arrows), with an overall increase in the luminal area. (C) After implantation of drug-eluting stents, the fractures were noted to become deeper (arrows), with further increase in acute area gain, resulting in favorable stent expansion and apposition.
