An 8-Fr XB 3.5 SH guiding catheter (A&A MD) was engaged via the femoral artery. He was referred to our department for treatment of diffuse stenosis in the proximal-to-mid LAD and tight stenosis of the ostium of the diagonal branch ( Fig. After PCI, the patient was discharged without complications.Ī 60-year-old male presented with effort angina over the past 2 months. Final angiography revealed a well-expanded stent without dissection or flow limitation of the SB ( Fig. 1F, Supplementary Video 2, only online). After recrossing, high-pressure post-dilation (3.0×15 mm noncompliant balloon) was performed with the Corsair catheter at the SB (kissing-Corsair technique Fig. The Corsair was recrossed to the SB under balloon anchoring (2.5×14 mm) at the OM stent ( Fig. After stenting, the jailed Corsair was removed by rotation, and rewiring was performed through the stent struts ( Fig. 1C, Supplementary Video 1, only online). After pre-dilation (2.5×14-mm semi-compliant balloon), a 3.0×28-mm everolimus-eluting stent (Synergy, Boston Scientific, Natick, MA, USA) was implanted into the OM branch under nominal inflation pressure (11 atm) with the Corsair catheter jailed at the SB (jailed-Corsair technique) ( Fig. Conventional guide wires (Runthrough wire, Terumo Medical Corporation, Somerset, NJ, USA Pilot wire, Abbott Vascular) were inserted into both OM branches, the main target vessel, and LCx proper (SB), and then a Corsair microcatheter (Asahi Intecc, Nagoya, Japan) was inserted into the SB (LCx proper) for prevention of SB occlusion ( Fig. For PCI of the OM branch, a 7-Fr XB 3.5 SH guide catheter (A&A MD, Seongnam, Korea) was engaged via the femoral artery. Coronary angiography was performed and indicated severe stenosis at the obtuse marginal (OM) branch of the left circumferential artery (LCx) with a previous patent LAD stent (Xience Alpine, Abbott Vascular, Santa Clara, CA, USA) ( Fig. Laboratory findings revealed elevation of troponin T (71 ng/mL), suggestive of non-ST-segment elevation myocardial infarction. While initial electrocardiogram showed sinus rhythm, chest x-ray showed bilateral pulmonary congestion and cardiomegaly. Initial physical examination revealed bilateral coarse lung sounds and swelling of both legs with pitting edema. The patient had a history of PCI at the mid-left anterior descending coronary artery (LAD) 2 months prior. An 85-year-old female visited the emergency room due to severe dyspnea.
