BACKGROUND: The 1-year restenosis rate after standard balloon angioplasty (BA) of long lesions in below-the-knee arteries may be as high as 70%. Our aim was to investigate the efficacy and safety of paclitaxel drug-eluting balloon (DEB) for treatment of below the knee lesions in end stage renal disease patients (ESRD) with critical limb ischemia (CLI). METHODS: Our study is a retrospective, single-center study. Inclusion criteria were ESRD, critical limb ischemia (Rutherford class 4 or higher) and significant stenosis or occlusion of at least 1 below-the-knee vessel...

The long-term outcomes of patients who underwent paclitaxel-coated balloon (PCB) angioplasty for drug-eluting stent restenosis (DES-ISR) remain unclear. We investigated the 5-year safety and efficacy outcomes of PCB angioplasty for DES-ISR. The study included 185 patients with 216 DES-ISR lesions who underwent PCB angioplasty from September 2008 to December 2010. Two serial angiographic follow-ups were routinely scheduled at 6 and 18 months after the index procedure. Five-year clinical outcomes were investigated...

BACKGROUND: Heavy coronary artery calcification is responsible for stent underexpansion, which is associated with increased in-stent restenosis. Here we report a case in which optical coherence tomography (OCT) demonstrated that the metal component of an underexpanded stent previously implanted in a heavy calcified lesion had been completely removed after ablation with rotational atherectomy. CASE PRESENTATION: An 83-year-old man with exertional angina was referred to our hospital...

BACKGROUND: Drug-eluting stent (DES) -induced coronary vasospasm is a well known phenomenon after stent implantation; however, the extent of this risk is still unknown. We report a case in which DES-induced severe coronary vasospasm was clinically suspected as a cause of subacute stent thrombosis (ST). CASE PRESENTATION: A 67-year-old man came to our hospital due to chest pain with mild exercise. He was diagnosed with effort angina by coronary angiography and underwent DES implantation in the mid-left ascending artery (LAD) after the administration of dual anti-platelet therapy...

BACKGROUND: There has been increasing evidence to support the endovascular- first approach in the treatment of below the knee (BTK) lesions. Plain Old Balloon Angioplasty (POBA), with bailout bare-metal stent scaffolding in case of flow limiting dissection or recoil, have been considered the standard treatment of choice but industries are continually developing innovative equipment and dedicated technologies, such as drug-eluting platforms whose use is increasingly extended, despite significant costs and lack of high-quality evidence to support a well- established strategy...

Drug-eluting stents have been used widely to prevent restenosis of arteries following percutaneous balloon angioplasty. Mathematical modelling plays an important role in optimising the design of these stents to maximise their efficiency. When designing a drug-eluting stent system, we expect to have a sufficient amount of drug being released into the artery wall for a sufficient period to prevent restenosis. In this paper, a simple model is considered to provide an elementary description of drug release into artery tissue from an implanted stent...

The lumen diameter reduction after percutaneous coronary intervention (PCI) is well known as "restenosis". This phenomenon is due to vessel remodeling/recoil in case of no-stent strategy or, in case of stent employ, "neointimal proliferation" that consists in an excessive tissue proliferation in the luminal surface of the stent otherwise by a further new-occurring atherosclerotic process called "neoatherosclerosis". The exact incidence of in-stent restenosis (ISR) is not easy to determine caused by different clinical, angiographic and operative factors...

BACKGROUND: Treatment of superficial femoral artery (SFA) lesions remains challenging. We conducted a network meta-analysis of randomized controlled trials aiming to explore the efficacy of treatment modalities for SFA "de novo" lesions. METHODS: Eleven treatments for SFA occlusive disease were recognized. We used primary patency and binary restenosis at 12-month follow-up as proxies of efficacy for the treatment of SFA lesions. RESULTS: A total of 33 studies (66 study arms; 4659 patients) were deemed eligible...

OBJECTIVES: The aim of this study is to summarize the outcomes of patients undergoing direct stenting (DS) with drug-eluting stents (DES) compared to those who underwent balloon predilatation. BACKGROUND: DS has been associated with improved outcomes in the bare-metal stent era. Although DS with DES implantation has been increasingly adopted in clinical practice, its safety and effectiveness remain controversial. METHODS: The search criteria identified 546 studies in the Medline/PubMed, Cochrane, and EMBASE databases from 2001 to July 2014...

BACKGROUND: Bailout stenting after suboptimal paclitaxel-coated balloon (PCB) angioplasty is required in up to 28% of cases. We sought to compare the safety of bailout stenting with drug-eluting stents (DES) compared with the more established combination of PCB with bare metal stents (BMS). METHODS: We retrospectively evaluated all patients who had stents implanted owing to suboptimal PCB angioplasty results between January 2010 and April 2015. Endpoints analyzed were major adverse cardiac events (MACE) - defined as cardiovascular death, nonfatal myocardial infarction (MI), and target lesion revascularization (TLR) - as well as major and minor bleeding...

BACKGROUND: The drug-eluting balloon (DEB) is a promising tool to prevent restenosis after coronary angioplasty. However, data on the outcomes of DEB in de novo lesions are scarce. Vessel recoil and constrictive remodeling are the dominant causes of restenosis after angioplasty. The use of cutting balloons (CB) may effectively reduce elastic recoil after balloon dilation. In this study, we evaluate the efficacy and safety of DEB in treating de novo coronary artery lesions, using a predilation strategy with cutting balloon (CB) dilation before DEB angioplasty...

OBJECTIVES: Data on bioresorbable vascular scaffolds for recanalization of chronic total occlusions (CTOs) are limited. We compared the bioresorbable scaffold Absorb with everolimus-eluting stents for the treatment of true CTO. METHODS: After recanalization of CTO, 15 lesions treated with the bioresorbable scaffold Absorb were matched with 15 lesions receiving everolimus-eluting stent (EES) (http://www.clinicaltrials.gov NCT02162082). Match criteria were presence of diabetes mellitus, total device length and maximal device diameter...

Bioresorbable scaffolds (BRS) combine attributes of the preceding generations of percutaneous coronary intervention (PCI) devices with new technologies to result in a novel therapy promoted as being the fourth generation of PCI. By providing mechanical support and drug elution to suppress restenosis, BRS initially function similarly to drug eluting stents. Thereafter, through their degradation, BRS undergo a decline in radial strength, allowing a gradual transition of mechanical function from the scaffold back to the artery in order to provide long term effectiveness similar to balloon angioplasty...

The drug coated balloon (DCB) platform offers several theoretical benefits over stent-based technologies. It allows the homogenous transfer of an anti-proliferative drug to reduce neo-intimal hyperplasia whilst potentially maintaining normal vessel anatomy and function. They also avoid the introduction of an additional stent layer in the context of in-stent restenosis. The data pertaining to the treatment of de-novo coronary disease still favors the new generation of drug eluting stents. DCB may, however, have a role in the context of challenging coronary anatomy and small vessel disease where results with stent insertion are poor...

Endovascular management of peripheral artery disease was until recently limited to percutaneous balloon angioplasty, atherectomy, stent grafts, and bare-metal stents. These therapies have been valuable, but plagued by high restenosis and revascularization rates. Important progress has been made with the introduction of combination devices, including drug-eluting stents and drug-coated balloons (DCB), designed to combat restenosis by locally delivering anti-proliferative drugs. In particular, promising clinical performance has been seen with the Medtronic IN...
