The treatment of coronary small vessel disease (SVD) remains an unresolved issue. Drug-eluting stents (DES) have limited efficacy due to increased rates of instent-restenosis, mainly caused by late lumen loss. Drug-coated balloons (DCB) are a promising technique because native vessels remain structurally unchanged. Basel Stent Kosten-Effektivitäts Trial: Drug-Coated Balloons vs. Drug-Eluting Stents in Small Vessel Interventions (BASKET-SMALL 2) is a multicenter, randomized, controlled, noninferiority trial of DCB vs DES in native SVD for clinical endpoints...

BACKGROUND: FDA approved the Gore Viabahn (WL Gore, Flagstaff, AZ, USA) stent for both femoro-popliteal arterial denovo and instent restenosis (ISRS) lesions. To date there is little data on Viabahn stent graft outcomes in ISRS arterial disease. METHODS: Between 2007 and 2014 we identified 734 patients who underwent 1573 endovascular interventions in our institution for infra-inguinal revascularization. Among these, 48 patients had 143 Viabahn stents placed. Of these, 26 patients had 94 stents placed for ISRS and 22 patients had 49 stents placed for denovo lesions...

Longitudinal rotational atherectomy of metal struts is well described as bail-out strategy to treat undilatable instent restenosis. Ablation of metal stent struts jailing the ostium of a major side branch in a coronary bifurcation is not described. In the current report, we describe a case of "transverse" rotational atherectomy to treat a failure of culotte stenting in a left main stem bifurcation. We document for the first time in vivo and in man the effect of this strategy using optical coherence tomography...

Optical coherence tomography (OCT) has emerged as a powerful intravascular imaging modality in recent years. The introduction of frequency-domain OCT has simplified the procedure and enabled its safe utilisation in different clinical settings including acute coronary syndromes, where it can determine the mechanism of plaque disruption, thrombus burden, and guide percutaneous coronary intervention. In patients presenting with stent failure (stent thrombosis and instent restenosis), OCT can also be very useful in determining the underlying mechanism and guiding therapy thereafter...

Despite the progress in endovascular treatment of patients with peripheral arterial disease, restenosis remains the major drawback, especially in patients with femoropopliteal lesions. To reduce neointimal proliferation and subsequent restenosis the use of antiproliferative drug eluting devices was implemented in the endovascular treatment of femoropopliteal disease. Aiming to use the favorable effects of these antiproliferative agents and to reduce foreign body exposure in affected arteries, drug coated balloons (DCB) have been developed...

Approximately 27 million people in Europe and North America currently have peripheral arterial disease (PAD). The endovascular treatment of stenosis or blocked peripheral arteries in PAD include percutaneous transluminal angioplasty with or without a drug coated balloon (DCB), atherectomy (rotational, directional, orbital or laser), and stenting. The development of next generation peripheral stents and drug-coated stents have led to the improved treatment of complex superficial femoral artery (SFA) lesions, and consequently increased their usage...

Currently, percutaneous coronary intervention (PCI) with drug-eluting stents (DES) is the most commonly employed modality in the treatment of patients with coronary artery disease. PCI has come of age over the last four decades with enormous forays in the technology and drugs which have greatly enhanced its capability. Angioplasty and bare metal stents were plagued by high failure rates on account of restenosis leading to repeat revascularization procedures. Insights into pathophysiology of instent restenosis (ISR) and neointimal hyperplasia triggered the development of DES...

We describe a patient who underwent coronary artery bypass grafting (CABG) surgery with the presentation of acute coronary syndrome (ACS). The diagnostic coronary angiogram showed acute thrombotic and occluded saphenous vein graft (SVG) and proximal right coronary artery (RCA) drug eluting stent (DES) instent restenosis (ISR) with chronic total occlusion (CTO). Our strategy was to recanalize the native left circumflex coronary artery (LCx) CTO instead of SVG or RCA instent CTO. After heparinization for 5 days, the LCx antegrade approach and the retrograde approach from left anterior descending coronary artery (LAD) septal branches were first attempted but failed, and the LCx CTO was successfully revascularized retrogradely via the acute thrombotic SVG without an embolic protection device (EPD)...

Introducing anti-restenotic drug-based treatment modalities in femoropopliteal interventions is the potential revolutionizing reperfusion treatment of peripheral artery disease. Durability of recanalization procedures using drug-coated balloons (DCB) and drug-eluting stents (DES) yields in excellent mid-term and long-term technical and clinical outcomes and may be cost saving on the long term as compared to traditional treatment modalities such as plain old balloon angioplasty (POBA) and bare metal nitinol stent implantation...

The new generation drug eluting stents have improved the results of coronary angioplasty by reducing the rate of instent restenosis and stent thrombosis compared to earlier devices, due to the thinner stent struts and improved or bioresorbable polymers. But permanent metallic stent struts may have some long term harmful effects such as inducing late thrombosis, neoatherosclerosis, restenosis and also impairing vasomotion and endothelial function. This was the rationale for introducing bioresorbable stents which offer radial support to the artery during the period needed (scaffolding) and then disappear, (liberating the vessels and restoring its physiological vasomotion...

Since Gruentizg's first percutaneous transluminal ballon angioplasty in 1977 in Zurich, percuta. neous coronary intervention evolved significantly in order to overcome the numerous associated complications of each technique. Bare-metal stents (BMS) made their initial appearance followed by three generations of drug-eluting stents (DES). The use of bioabsorbable vascular scaffold stents (BVS) has become more frequent creating a temporary scaffold allowing healing of the endothelium within 2 years. In this article, we discuss the nomenclature of the main intravascular complications linked to percuta...
