BACKGROUND The patency and complications in aorto-iliac (AI) stenting remain poorly understood. The aim of this paper was to investigate the safety and efficacy after AI stenting. METHODS AND RESULTS This study was performed as a large-scale multicenter, retrospective registry. A total of 2,147 consecutive patients with AI disease were enrolled. The(More)
OBJECTIVE Takayasu arteritis (TAK) is a rare autoimmune arteritis that affects large arteries. Although the association between TAK and HLA-B 52:01 is established, the other susceptibility HLA-B alleles are not fully known. We performed genetic association studies to determine independent HLA-B susceptibility alleles other than HLA-B 52:01 and to identify(More)
BACKGROUND Late adverse events such as very late stent thrombosis (VLST) or late target-lesion revascularization (TLR) after first-generation sirolimus-eluting stents (SES) implantation have not been yet fully characterized at long term in comparison with those after bare-metal stent (BMS) implantation. METHODS AND RESULTS Among 13 058 consecutive(More)
BACKGROUND The P2Y(12) adenosine diphosphate (ADP) receptor blocker, clopidogrel, an essential drug for the prevention of stent thrombosis after percutaneous coronary intervention (PCI), is a prodrug that requires CYP2C19- and CYP3A4-mediating activation. CYP2C19*2 and *3 polymorphisms are known to lack enzymatic activity. CYP2C19 polymorphisms have been(More)
AIM Clopidogrel, an essential drug for the prevention of stent thrombosis, is a prodrug activated by CYP enzyme family including CYP2C19. It is known that activity-defective polymorphisms of CYP2C19 (CYP2C19*2 and*3) are associated with reduced clopidogrel efficacy and poor prognosis. Recently, the (13)C-pantoprazole breath test is developed to evaluate the(More)
BACKGROUND The influence of β-blocker therapy on prognosis in patients with coronary artery disease (CAD) who underwent percutaneous coronary intervention (PCI) has not been fully explored. METHODS AND RESULTS We identified 5288 CAD patients who did not have myocardial infarction (MI) or heart failure (HF) but underwent PCI from a large multi-center(More)
Takayasu arteritis (TAK) is an autoimmune systemic vasculitis of unknown etiology. Although previous studies have revealed that HLA-B*52:01 has an effect on TAK susceptibility, no other genetic determinants have been established so far. Here, we performed genome scanning of 167 TAK cases and 663 healthy controls via Illumina Infinium Human Exome BeadChip(More)
OBJECTIVES To investigate factors associated with 30-day perioperative complications (POC) after aorto-iliac (AI) stenting, and to compare follow-up cardiovascular prognosis between patients with and without POC. MATERIALS AND METHODS This was a retrospective multicenter study. We used a multicenter database of 2012 consecutive patients who successfully(More)
OBJECTIVES To investigate factors in patients with critical limb ischemia (CLI) and isolated infrapopliteal lesions that adversely affect outcomes of endovascular therapy (EVT) with or without angiosome-oriented revascularization. METHODS This was a retrospective multicenter study. We used a database of 718 consecutive CLI patients (70 ± 11 years, 75%(More)
Percutaneous transcatheter mitral valvuloplasty is the indicated treatment of choice for symptomatic native mitral valve stenosis, but there have been limited reports of successful procedures of balloon valvuloplasty for bioprosthetic mitral valve stenosis. We present the case of a 62-year-old woman suffering from progressive dyspnea due to bioprosthetic(More)
