    Abstract Cardiac magnetic resonance (CMR) imaging could enable major advantages when guiding in real-time cardiac electrophysiology procedures offering high-resolution anatomy, arrhythmia substrate, and ablation lesion visualization in the absence of ionizing radiation. Over the last decade, technologies and platforms for performing electrophysiology procedures in a CMR environment have been developed. However, performing procedures outside the conventional fluoroscopic laboratory posed technical, practical and safety concerns. The development of magnetic resonance imaging compatible ablation systems, the recording of high-quality electrograms despite significant electromagnetic interference and reliable methods for catheter visualization and lesion assessment are the main limiting factors. The first human reports, in order to establish a procedural workflow, have rationally focused on the relatively simple typical atrial flutter ablation and have shown that CMR-guided cavotricuspid isthmus ablation represents a valid alternative to conventional ablation. Potential expansion to other more complex arrhythmias, especially ventricular tachycardia and atrial fibrillation, would be of essential impact, taking into consideration the widespread use of substrate-based strategies. Importantly, all limitations need to be solved before application of CMR-guided ablation in a broad clinical setting.

    Abstract Antiplatelet therapy with aspirin or clopidogrel or both is the standard care for patients with proven coronary or peripheral arterial disease, especially those undergoing endovascular revascularization procedures. However, despite the administration of the antiplatelet regiments, some patients still experience recurrent cardiovascular ischemic events. So far, it is well documented by several studies that in vitro response of platelets may be extremely variable. Poor antiplatelet effect of clopidogrel or high on-treatment platelet reactivity (HTPR) is under investigation by numerous recent studies. This review article focuses on methods used for the ex vivo evaluation of HTPR, as well as on the possible underlying mechanisms and the clinical consequences of this entity. Alternative therapeutic options and future directions are also addressed.

    Abstract Intussusception in adults is rare, accounting for less than 5% of all cases. Unlike the childhood variant, adult intussusception is often associated with a small bowel lesion acting as the "lead point." We herein report an uncommon case of giant intussusception secondary to 2 separate lipomatous lesions located in the ileum, in an adult admitted to our hospital for acute severe abdominal pain.

    Abstract Endovascular procedures for the management of the superficial femoral (SFA) and popliteal artery disease are increasingly common. Over the past decade, several stent technologies have been established which may offer new options for improved clinical outcomes. This paper reviews the current evidence for SFA and popliteal artery angioplasty and stenting, with a focus on randomized trials and registries of nitinol self-expanding stents, drug-eluting stents, dug-coated balloons, and covered stent-grafts. We also highlight the limitations of the currently available data and the future routes in peripheral arterial disease (PAD) stent and balloon technology.

    Abstract Purpose: This study was designed to investigate the long-term angiographic and clinical outcomes of percutaneous transluminal angioplasty (PTA) of the arteria profunda femoralis (PFA), in a series of patients suffering from critical limb ischemia (CLI) or severe intermittent claudication (IC).
    Methods: Our department's database was searched to identify patients who underwent PTA or bail-out stenting of the PFA. Among the study's inclusion criteria were Rutherford categories 3-6 and ≥70% stenosis of the PFA. Only de novo stenotic lesions were assessed. Primary endpoints were technical success, angiographic lesion primary patency, angiographic binary in-lesion restenosis, and target lesion recanalization (TLR) rates. Secondary endpoints included patient survival, limb salvage, and complication rates. Patient's baseline demographics, lesion, and procedural details were analyzed.
    Results: Between 2001 and 2011, 20 consecutive patients (17 males) with a mean age of 73 ± 9 (range 53-87) years underwent PTA or bail-out stenting in 23 PFA lesions. Critical limb ischemia was the indication in eight of 20 patients (40%). The mean lesion length was 31 ± 9.5 mm. The procedural technical success was 100% (23/23), whereas mean time angiographic and clinical follow-up was 26.8 ± 24.6 months. According to the Kaplan-Meier analysis, primary patency and binary restenosis rate were 95 and 86.1% respectively up to 8 years follow-up. No TLR procedures were performed. The 8-year patient survival and limb salvage rates were 87.5 and 84.7% respectively.
    Conclusions: PTA or stenting of focal, stenotic, PFA lesions, in patients suffering from CLI or IC, exhibit high long-term primary patency rates, as well as low binary restenosis and TLR rates. Large, multicenter studies are required to validate these results.

    Abstract Purpose: This study was designed to determine the prevalence of platelet nonresponsiveness to aspirin using point of care testing in a population with symptomatic peripheral arterial disease (PAD).
    Methods: This was an observational, single-centre study including all patients with symptomatic PAD receiving aspirin. In patients receiving dual antiplatelet therapy with additional clopidogrel, platelet responsiveness to clopidogrel also was tested. Platelet responsiveness was assessed with the VerifyNow P2Y12 assay. Patients with residual aspirin reaction units ≥550 and platelet reactivity units ≥234 were considered nonresponders. The study's primary endpoint was to determine the prevalence of nonresponsiveness to aspirin; secondary endpoints included the prevalence of dual nonresponsiveness.
    Results: In total, 145 consecutive patients (mean age 67 ± 9 years) receiving aspirin 100 mg were tested, whereas 128 of 145 (88.3 %) were under dual antiplatelet therapy with additional clopidogrel 75 mg. The prevalence of nonresponsiveness to aspirin was 20.7 % (30/145). Among the 128 patients receiving dual antiplatelet therapy, 65 (50.8 %) demonstrated nonresponsiveness to clopidogrel and 16 (11.7 %) dual nonresponsiveness to both aspirin and clopidogrel. Aspirin nonresponsiveness was not significantly different in patients suffering from diabetes, renal disease, critical limb ischemia (CLI) or those receiving statin, antihypertensive or proton-pump inhibitors therapy. Clopidogrel nonresponsiveness was significantly higher in older patients (p = 0.01) and those suffering from CLI (p = 0.03) and renal disease (p = 0.001) and significantly lower in smokers (p = 0.01).
    Conclusions: The prevalence of platelet nonresponsiveness to aspirin detected using the VerifyNow point of care testing in symptomatic PAD patients was 20.7 % and the clinical impact of the phenomenon merits further investigation.
