Abstract
AbstractA 49‐year‐old male presented with class III exertional angina, 1 year after angioplasty of the left anterior descending artery (LAD) and right coronary artery. Coronary angiogram revealed 90% in‐stent restenosis (ISR) in mid‐LAD with angiographic impression of stent fracture. Optical coherence tomographic evaluation of mid‐LAD ISR showed a distinct 3 mm long “eclipse sign” indicating embolized, broken guiding catheter tip as a cause of ISR, which was confirmed on reviewing 1‐year‐old angiographic images. This was managed with “cut and fix technique” using cutting balloon and another drug‐eluting stent. Optical coherence tomographic at 9 months showed well endothelialized stent with a thin layer of neo‐intimal hyperplasia over the sandwiched broken guiding tip.
