A successful treatment for a lesion of chronic total occlusion using a virtual 3 Fr guiding catheter.
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.
