文摘

A 67-year-old woman was admitted with an acute coronary syndrome. Angiographic examination revealed diffuse severe stenosis of the left circumflex artery. A Pressure Wire Certus (St. Jude Medical, St. Paul, MN, USA) was passed to the second post-lateral (PL) branch. To prevent side-branch occlusion, a SION wire (Asahi Intecc Co., Aichi, Japan) was left in the first PL branch, and a SION blue wire (Asahi Intecc) was placed in the second obtuse marginal branch. We implanted an everolimus-eluting stent (PROMUS Element 2.5?×?24?mm, Boston Scientific, Natick, MA, USA) in the culprit lesion. After retrieving the protection wire in first PL branch with resistance, we performed post-dilatation. However, the intravascular ultrasound images showed that the proximal portion of the implanted stent had elongated approximately 2?mm to the left main trunk (LMT), although the position of the distal edge of the stent was unchanged. We decided to additionally place a stent from the ostium of the LMT to the proximal left anterior descending coronary artery, and a biolimus-eluting stent (NOBORI 3.0?×?18?mm, Terumo Co., Tokyo, Japan) was implanted successfully. Longitudinal stent elongation might be caused by the small number of links between the hoops of a stent, originally intended to improve deliverability.
