    Limitations of percutaneous coronary intervention have been partially overcome with the advent of Drug-eluting stents (DESs), which have offered better results than bare-metal stents (BMSs), and the DESs of second-generation surpass the clinical results of first generation ones. Stent thrombosis (ST) and in-stent restenosis (ISR) are the major late complications of percutaneous coronary intervention. There has been a downward trend in the incidence of ST with the advent of newer stent designs and dual antiplatelet therapy. A few long-term follow-up studies of Bioresorbable Vascular Scaffolds failed to show significant benefits, besides showing an increased incidence of stent thrombosis and thus warrant further research. ISR with bare-metal stent implantation is relatively stable, with an early peak of intimal growth and later regression. In contrast, ISR in the case of DES is characterized by a late catch-up phenomenon with intimal hyperplasia during long-term follow-up. Neoatherosclerosis with chronic inflammation has become known to play a major role in late stent failure with both BMSs and DESs.

    Reel syndrome is a very rare cause of pacemaker malfunction. Reel syndrome has been described as a variant of twiddlers syndrome, characterized by reeling-in of the pacemaker lead. It occurs due to the rotation of the pulse generator on its transverse axis with subsequent coiling of the pacemaker leads around the pulse generator, resulting in dislodgement and/or retraction of the pacing lead with loss of pacing function. We report a case of Reel syndrome with a single chamber pacemaker, in which an actively fixated ventricular lead was coiled around the generator.

    Background: The intra-aortic balloon pump (IABP) is a common therapy available for ventricular support in critical cardiac patients. The aim of this study was to characterize the effect of IABP on endothelial function, on serum B-type natriuretic peptide (BNP) levels and on central venous oxygen saturation (ScVO2) and arteriovenous carbon dioxide gradient (ΔPCO2) as perfusion tissue markers.
    Methods and results: Twenty-three patients with severe heart failure, mean age 5013 years, left ventricular ejection fraction of 228% were included. All were on IABP support and the protocol considered 3 conditions: 1) IABP ratio 1:1, 2) IABP ratio 1:3 and 3) IAPB ratio 1:1. The period of time between conditions was 20 minutes. In the three conditions the endothelial-dependent flow-mediated vasodilatation (FMD) was measured by ultrasound method. Blood was sampled to determine ScVO2, ΔPCO2 and BNP. FMD was impaired, ΔPCO2 and BNP were high, compatible with severe heart failure, but did not change with IABP variation. ScVO2 (%) was 68.310.2 and 61.312.5, p<0.002 (condition 1 vs. 2). The values were also significant considering the condition 2 vs. 3 when ScVO2 was 61.312.5 and 64.89.7, p=0.035 respectively.
    Conclusions: The FMD, ΔPCO2 and BNP were abnormal secondary to decompensated heart failure but did not change with the variation of IABP support. The ScVO2 proved to be a sensitive tissue perfusion marker to evaluate the response of mechanical support even in short periods of time. The ScVO2 may represent an excellent clinical monitoring tool for patients on IABP as well as assistance to their weaning.

    Endovascular repair has become widespread in the treatment of aortoiliac and femoropopliteal disease, however, in common femoral artery (CFA) disease it remains unclear whether endovascular repair is preferred to open common femoral artery endarterectomy. We report a review of 101 patients who underwent unilateral or bilateral common femoral endarterectomies and/or profundaplasties at our institution. Thirty-day operative mortality was 5%. Complications observed included bleeding (3%), pneumonia (3%), deep wound infection (8%), sepsis (3%), stroke (3%) and myocardial infarction (2%). Our patient cohort demonstrates encouraging short and medium-term outcomes in a high-risk patient population.
