RESUMO
A 43 year-old man was admitted due to effort related chest squeezing for 3 months. Coronary angiogram showed a total occlusion of the proximal right coronary artery (RCA) with collateral vessels from left anterior descending artery. The 5F sheathless guiding catheter was engaged into the RCA and the 3F JL3.5 catheter was inserted into left coronary artery via left radial artery for simultaneous contra lateral angiography. We advanced the wire through the lesion with 2 wire technique. Three XIENCE stents (2.5 mm × 28 mm) was inserted from distal to mid RCA, and a 3.0 mm × 15 mm XIENCE stent was inserted to proximal RCA. The final angiographic result showed well expanded stent. The treatment of chronic total occlusion could be possible even slender device by getting hold of the characteristics of the device and evaluating an objective assessment of lesion characteristics.

An 83-year-old woman was admitted due to effort related chest squeezing over the duration of 5 months. A coronary angiogram revealed significant in-stent restenosis at proximal left anterior descending artery. Optical coherence tomography (OCT) image acquisition was successfully performed using a non-occlusive technique. Restenotic tissue consisting of eccentric layers was observed by the OCT. The only imaging method of intracoronary evaluation using a 4F guiding catheter is an OCT. An OCT assessment was helpful for the percutaneous coronary intervention using a 4F guiding catheter.
