A 64-year-old female underwent a successful first percutaneous intervention using MISAGO stents for a de novo femoropopliteal lesion. Subsequently, three more effective procedures were done using balloon catheters for in-stent restenosis. In May 2016, a fourth procedure using Zilver PTX stent for in-stent restenosis was carried out.

DNA double-strand breaks (DSBs) of peripheral blood lymphocyte were prospectively assessed in 9 patients who were injected with Tl-chloride and I-beta-methyl-p-iodophenyl-pentadecanoic acid in dual-isotope imaging. Phosphorylated H2AX (γH2AX) was used as a biomarker for detecting DSBs, and the mean number of γH2AX foci per cell was measured microscopically. Mean γH2AX foci before administration of radiopharmaceuticals and at 3, 6, and 24 h following administration were 0.

Early 80s male with intermitted claudication underwent endovascular therapy for atherosclerotic stenosis at left external iliac artery and middle of superficial femoral artery. Patient also had chronic atrial fibrillation, diabetes mellitus, and hypertension. After stent deployment for external iliac artery lesion, a short superficial femoral artery lesion was performed with angioplasty using drug-coated balloon.

Objective: Nitinol stenting could bring the better outcome in endovascular therapy for femoropopliteal disease. However, it might be expected that recent marked advances in both device technology and operator technique had led to improved efficacy of balloon angioplasty even in this segment. The aims of this study were to evaluate the clinical impact of balloon angioplasty for femoropopliteal disease and make risk stratification clear by propensity score matching analysis.

Objective: Patients categorized Rutherford category IV might have different characteristics compared with Rutherford category V and VI. Our study aims were to estimate the clinical differences between Rutherford category IV and Rutherford category V and VI, for those underwent endovascular therapy for isolated infrapopliteal disease, and also to find risk factors for endovascular therapy in Rutherford category IV.

Methods: Based on the Japanese multi-center registry data, 1091 patients with 1332 limbs (Rutherford category IV: 226 patients with 315 limbs, Rutherford category V and VI: 865 patients with 1017 limbs) were analyzed retrospectively.

Background: The aim of this study was to compare global and regional left ventricular function in patients with coronary artery disease (CAD), obtained by use of Cedars-Sinai quantitative gated single photon emission computed tomography (QGS), for gated nitrogen 13 ammonia (NH(3)) positron emission tomography (PET) and technetium 99m sestamibi (MIBI) single photon emission computed tomography (SPECT).

Methods And Results: Fifty-one patients with CAD underwent gated N-13 NH(3) PET and gated MIBI SPECT. The end-diastolic volume, end-systolic volume, and ejection fraction were calculated by use of QGS.

Background: Electrocardiographic gated 13N-ammonia positron emission tomography (PET) enables simultaneous assessment of myocardial blood flow and left ventricular (LV) function. The aim of this study was to assess the accuracy of gated 13N-ammonia PET for evaluating global and regional LV function in patients with coronary artery disease (CAD) in comparison with conventional left ventriculography (LVG).

Methods And Results: Fifty-four patients with CAD underwent gated 13N-ammonia PET and LVG.

Transient glucose deprivation (TGD) has been shown to induce a resistance to a subsequent ischemia and reperfusion injury in the heart. Induction of cyclooxygenase-2 (COX-2) and heme oxygenase-1 (HO-1) is known to mediate the powerful defensive adaptation of the heart against oxidative stress. In this study, we found that a 30-min incubation in the absence of glucose resulted in a rapid increased expression of COX-2 and HO-1 in cardiac fibroblasts as examined by real-time quantitative polymerase chain reaction (PCR) and western blot analysis.
