OBJECTIVE To compare long-term patency after endovascular therapy (EVT) for superficial femoral artery (SFA) occlusive disease between patients with hemodialysis (HD; HD+) and those without HD (HD-). BACKGROUND Long-term patency after EVT for SFA occlusive disease in HD+ remains unknown. METHODS EVT to SFA was successfully performed in 382 consecutive(More)
Neovascularization such as formation of collateral vessels following total occlusion of native coronary artery is common in coronary artery disease. This is a case report of a very rare connection by newly formed conduit vessels between the left internal mammalian artery and the radial artery establishing bypass, which occurred after failure of bypass(More)
BACKGROUND AND PURPOSE Octogenarians (age ≥ 80 years) with coronary artery disease constitute a high-risk group. However, octogenarian patients with acute myocardial infarction (AMI) in the drug-eluting stents (DES) era have not been widely reported. We aimed to identify clinical outcomes in octogenarian compared with non-octogenarian AMI patients. (More)
BACKGROUND Although patients receiving hemodialysis (HD+) have significantly different backgrounds, including a history of progressive atherosclerotic disease, compared with those not receiving hemodialysis (HD-), there are no studies evaluating the risks for loss of primary patency (PP) and need for target lesion revascularization (TLR) in HD+ patients(More)
BACKGROUND Optimal treatment strategies for restenosis of sirolimus-eluting stents (SES) have not been adequately addressed yet. METHODS AND RESULTS During the 3-year follow-up of 12 824 patients enrolled in the j-Cypher registry, 1456 lesions in 1298 patients underwent target-lesion revascularization (TLR). Excluding 362 lesions undergoing TLR for stent(More)
In atherosclerosis, carotid artery stenosis (CAS), renal artery stenosis (RAS), lower extremity peripheral arterial disease (PAD), and coronary artery disease (CAD) are common pathologic lesions; their interrelationship is, however, unclear. We studied concomitant multiple atherosclerotic lesions in patients with CAD to understand their prevalence and(More)
BACKGROUND We used intravascular ultrasound (IVUS) to evaluate the association of tissue prolapse (TP) with short- and long-term outcomes after stent implantation in 418 acute myocardial infarction (AMI) patients. METHODS We evaluated the incidences of stent thrombosis, no-reflow, and long-term outcomes between patients with TP (n=142) and those without(More)
The aim of the present study was to evaluate the plaque components and the predictors of thin-cap fibroatheroma (TCFA) in anemic patients with acute coronary syndrome using virtual histology-intravascular ultrasound (VH-IVUS). Anemia was defined according to criteria of the World Health Organization, (i.e. , hemoglobin levels < 13 g/dL in men and < 12 g/dL(More)
