Roberto Gandini, Costantino Del Giudice
OBJECTIVES: The aim of this study was to evaluate the safety and efficacy of percutaneous catheter-delivered ultrasound energy to improve local paclitaxel delivery effects in patients with critical limb ischemia (CLI) treated for femoral-popliteal arterial disease. BACKGROUND: Treatment of patients with CLI continues to be the greatest challenge in peripheral artery disease; in particular, treatment of femoral-popliteal chronic total occlusion is characterized by poor primary patency...

Drug-eluting balloons (DEB) may be considered as a "quiet revolution" in percutaneous coronary interventions. Early-generation DEB eluting paclitaxel proved to be very effective in animal models to reduce neointimal hyperplasia. Areas covered: Review of DEB efficacy in patients with coronary de novo lesions and in-stent restenosis (ISR). Expert opinion: Many randomized clinical trials and meta-analyses have demonstrated the value of DEB in patients with ISR. In this setting, DEB are safe and effective with clinical and angiographic results superior to plain balloon angioplasty and at least equivalent to first generation drug-eluting stents (DES)...

Rapamycin is an immunosuppressive agent that is added to drug eluting stents. It prevents restenosis, but it also impairs reendothelialization. Nicorandil is a hybrid agent with adenosine triphosphated (ATP)-sensitive K+ (KATP) channel opener and nitrate properties. It prevents oxidative stress and cell apoptosis induced by rapamycin in endothelial cells in vitro. However, whether nicorandil promotes reendothelialization after angioplasty delayed by rapamycin remains to be determined. Balloon injury model was established in SD rats...

PURPOSE: To report a Bayesian network meta-analysis of randomized controlled trials (RCTs) comparing bare metal stents (BMS), paclitaxel-coated balloons (PCBs), and drug-eluting stents (DES) with balloon angioplasty (BA) or with each other in the infrapopliteal arteries. METHODS: Sixteen RCTs comprising 1805 patients with 1-year median follow-up were analyzed. Bayesian random effects binomial models were employed (WinBUGS). Relative treatment effects were expressed as odds ratios (ORs) with 95% credible intervals (CrI), and the cumulative rank probabilities were calculated to provide hierarchies of competing treatments...

BACKGROUND: The treatment strategy for in-stent restenosis (ISR) with bifurcation lesions has not been well explored. We examined the clinical outcomes between final kissing balloon technique (FKBT) after stent implantation and single-stent implantation without FKBT for bifurcation ISR lesions. METHODS: We identified 115 consecutive ISR with bifurcation lesions among 108 patients who underwent drug-eluting stent implantation. The patients were divided into the FKBT group (34 patients, 35 lesions) and the non-FKBT group (74 patients, 80 lesions)...

Adhesion molecules play an important role in inflammation, atherosclerosis and coronary artery disease (CAD). These molecules are expressed on the surface of dysfunctional endothelial cells, causing inflammatory cells from the circulation to adhere and migrate through the endothelium. Their expression is upregulated in acute coronary syndrome (ACS) and after percutaneous coronary intervention (PCI). The contact between stent struts and endothelium upregulates endothelial cell gene expression, endothelial cell activation and inflammation...

The introduction of percutaneous treatment of coronary artery stenosis with balloon angioplasty was the first revolution in interventional cardiology; the advent of metallic coronary stents (bare and drug-eluting) marked the second and third revolutions. However, the latest generation of drug-eluting stents is limited by several factors. Permanent vessel caging impairs arterial physiology, and the incidence of very late stent thrombosis - although lower with the second generation than with the first generation of drug-eluting stents - remains a major concern...

Despite the high anti-restenotic efficacy of contemporary percutaneous interventional techniques, a substantial number of patients who undergo percutaneous coronary intervention (PCI) still present with restenosis. Despite iterations of devices- from plain balloon angioplasty to bare metal stenting (BMS) to drug-eluting stent (DES) therapy - have granted a progressive decline in the rate of this complication, in-stent restenosis remains a critical issue encountered in clinical practice. Owing to the overall increase in the use of DES, the number of patients presenting with DES restenosis is not insignificant in absolute terms...

BACKGROUND: Drug-eluting balloon (DEB) and standard percutaneous transluminal angioplasty (PTA) are commonly used endovascular therapeutic procedures for the revascularization of infrapopliteal arterial occlusive disease. However, which procedure is more beneficial for patients is unknown. METHODS AND RESULTS: We performed a meta-analysis, searching PubMed, EMBASE, the Cochrane Central Register of Controlled Trials, ISI Web of Knowledge, and relevant websites without language or publication date restrictions for randomized trials that compared DEB with PTA in patients with infrapopliteal arterial occlusive disease...

Endovascular techniques have improved markedly over the past several decades. Plain old balloon angioplasty can only reach patencies around 40% after 1 year. Scaffolding stents have resulted in improved short-term results but encountered limitations for longer-term durability. With the introduction of drug-eluting technologies the process of intimal hyperplasia might be slowed, resulting in improved long-term patency results. At first, limus-eluting technologies were not able to transfer the enthusiasm from the coronaries to the infrainguinal vascular bed...

INTRODUCTION: Stent delivery failure may occur especially when treating complex coronary artery stenosis. XLIMUS (CARDIONOVUM GmbH, Bonn, Germany) is a new sirolimus-eluting stent (SES) with the following features: 1) cobalt chromium stent platform, with low (73 μm) strut thickness, (2) biodegradable polymer, and 3) potent antiproliferative drug (Sirolimus). Preliminary data suggest that XLIMUS SES may be ideal for the treatment of complex lesions. METHODS: In this registry, we assessed the deliverability, safety, and efficacy of percutaneous coronary interventions (PCI) using the XLIMUS SES in patients undergoing elective PCI in native coronary vessels for complex de novo lesions, including severe calcification, severe tortuosity, and chronic total occlusion...

Peripheral arterial disease, particularly critical limb ischemia, is an area with urgent need for optimized therapies because, to date, vascular interventions often have limited life spans. In spite of initial encouraging technical success after femoropopliteal percutaneous transluminal angioplasty or stenting, postprocedural restenosis remains the major problem. The challenging idea behind the drug-coated balloon (DCB) concept is the biological modification of the injury response after balloon dilatation. Antiproliferative drugs administered via DCBs or drug-eluting stents are able to suppress neointimal hyperplasia, the main cause of restenosis...

OBJECTIVE: Although never assessed prospectively, diabetes mellitus (DM) is assumed to negatively affect the outcomes of critical limb ischemia (CLI). DM was highly prevalent in two recently conducted randomized controlled trials in CLI patients, the PADI (Percutaneous Transluminal Balloon Angioplasty [PTA] and Drug Eluting Stents for Infrapopliteal Lesions in Critical Limb Ischemia) and JUVENTAS (Rejuvenating Endothelial Progenitor Cells via Transcutaneous Intra-Arterial Supplementation) trials...

One third of patients with critical limb ischemia (CLI) has below the knee lesions and requires a restoration of direct blood flow into the foot. However, many of these patients are ineligible for open surgery. The primary goals thus become pain relief and limb salvage over patency. The angiosome concept helps determine the target artery to treat in priority. The endovascular approach has decreased morbidity and mortality rates compared to distal bypass surgery; while subintimal retrograde, trans-collateral and loop techniques push the limits of open surgery by reopening the plantar arch, thereby improving run-off...

OBJECTIVES: This study investigated the long-term outcomes and predictors of target vessel failure (a composite of cardiac death, myocardial infarction, stent thrombosis, or target vessel revascularization) in patients with bifurcation lesion treated by percutaneous coronary intervention (PCI) utilizing the 2-stent strategy with a drug-eluting stent (DES). BACKGROUND: There are limited data on outcomes of the 2-stent strategy in bifurcation PCI. METHODS: Patient-level pooled analysis was performed with patients undergoing PCI with 2-stent strategy from the Korean Bifurcation Pooled Cohorts...

BACKGROUND: Drug-coated balloons (DCB) have been used to treat de novo small vessel coronary disease (SVD), with promising results and shorter dual antiplatelet therapy (DAPT) duration compared to drug-eluting stents (DES). We compared safety and effectiveness of the two treatments at 1 year. METHODS: We reviewed 3,613 angioplasty cases retrospectively from 2011 to 2013 and identified 335 patients with SVD treated with device diameter of ≤2.5 mm. DCB-only angioplasty was performed in 172 patients, whereas 163 patients were treated with second-generation DES...

BACKGROUND: We designed a porcine model to compare the angiographic, optical coherence tomography (OCT) and histological findings of implanting an everolimus-eluting stent (EES) in the same segment of the coronary artery pre-treated with a drug-coating balloon (DCB; paccocath as carrier) with EES alone and DCB plus a bare metal stent (BMS). METHODS: Seven female swine averaging 46.0±2.4kg were treated by random assignment as follows: DCB followed by EES; DCB followed by BMS; and EES alone...
