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)
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)
OBJECTIVE To evaluate the clinical benefit of pre-procedural antiplatelet therapy in patients undergoing transfemoral (TF) transcatheter aortic valve implantation (TAVI). METHODS OCEAN (Optimized transCathEter vAlvular interveNtion)-TAVI is a prospective, multicentre, observational cohort registry, enrolling 749 patients who underwent TAVI from October(More)
OBJECTIVES This study describes the characteristics of a real-world Asian patient population treated with transcatheter aortic valve replacement (TAVR) and evaluates their clinical outcomes. BACKGROUND No previously reported randomized or observational studies adequately assess the safety and efficacy of TAVR in an Asian population. METHODS The Asian(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 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 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 this study was to evaluate postprocedural and midterm outcomes of transcatheter aortic valve implantation (TAVI) in patients with aortic stenosis and active cancer. From October 2013 to August 2015, a total of 749 patients undergoing TAVI using the Edwards Sapien XT prosthesis (Edwards Lifesciences, Irvine, California) were prospectively included(More)
