Outcomes after stenting of renal artery stenosis in patients with high-risk clinical features.

Background: In patients with renal artery stenosis, revascularization was seen as a mean to improve outcomes, but large studies failed to show significant benefit in general population. However, data on benefits of renal artery stenting in patients with high-risk features, such as rapidly declining renal function and cardiac destabilization syndromes, are limited, as they were excluded from trials. In this descriptive study, we aimed to evaluate short- and long-term outcomes in high-risk patients with renal artery stenosis, treated by angioplasty and stenting.

Long-term benefits of drug-coated balloons for coronary artery revascularization.

Percutaneous coronary intervention (PCI) with drug-eluting stents (DES) represents the treatment of choice for the majority of patients with coronary artery disease. While currently available DES, in addition to physiological support, has failed to show the non-inferiority to coronary artery bypass grafting (CABG) in terms of cumulative incidence of clinical events over the short-term follow-up. Studies have also shown that DES is associated with an increased risk of target vessel revascularization compared to CABG after long-term follow-up.

The fate of coronary dissections left after sirolimus-coated balloon angioplasty: A prespecified subanalysis of the EASTBOURNE study.

Objectives: We sought to understand the clinical outcomes of dissections left untreated after sirolimus drug-coated balloon (DCB) angioplasty.

Background: DCB may be a valuable alternative to stents for the treatment of native coronary lesions, but the risk of having a dissection after DCB-angioplasty is not negligible. While type A and B dissections can be safely treated conservatively, some debate exists regarding type C dissections.

Coronary stent failure: role of a blended approach with drug-coated balloons for complex lesions.

The management of coronary artery disease by means of percutaneous approach have been focused initially to overcome the recoil and acute occlusion after vessel ballooning; therefore, to develop and improve metallic stent platforms, and later drug-eluting technologies. Contemporarily, the necessity emerged to optimize interventional procedures using functional physiologic tests and intravascular imaging guidance, but still stent failures, especially in the complex lesion setting, continue to be not negligible. This comprehensive review is focused on the technology of drug-coated balloons as a tool to treat coronary artery disease without the need for metal implantation but still eluting antirestenotic drugs such as paclitaxel or sirolimus.

Intravascular imaging for left main stem assessment: An update on the most recent clinical data.

Left main (LM) stem has different structural and anatomical characteristics compared to all of the other segments of the coronary tree, thus its management through percutaneous coronary intervention (PCI) is a challenge and is associated with worse clinical outcome and higher need for revascularization as compared to other lesion settings. Intravascular imaging, by means of intravascular ultrasound (IVUS) or optical coherence tomography (OCT), is an important tool for LM PCI guidance, aiming at improving the immediate performance and the long term outcome of this procedure. Following current guidelines and recent scientific findings, IVUS becomes important to firstly assess, and finally evaluate the result of LM stenting, according to the experience and preferences of the operator.

Approaches to Peripheral Artery Disease in Diabetes: Are There Any Differences?

Peripheral artery disease (PAD) increases the risk of diabetes, while diabetes increases the risk of PAD, and certain symptoms in each disease increase the risk of contracting the other. This review aims to shed light on this harmful interplay between the two disorders, with an emphasis on the phenotype of a patient with both diabetes and PAD, and whether treatment should be individualized in this high-risk population. In addition, current guideline recommendations for the treatment of PAD were analyzed, in an attempt to establish the differences and evidence gaps across a population suffering from these two interconnected disorders.

Efficacy and Safety of a Dedicated Left Atrial Appendage Occlusion Protocol.

Objectives: The aim of this study is to present a dedicated left atrial appendage closure protocol, which could be of great interest in the approach of frail patients.

Background: Left atrial appendage (LAA) occlusion emerged as a promising therapeutic tool for stroke prevention, as most of the atrial fibrillation (AF) related strokes result from LAA thromboembolism, with an important residual risk even for anticoagulated patients. As an internationally recognized and scientifically-based protocol for the patients with higher comorbidities has not yet been defined for this procedure in terms of anaesthesia use or post procedural antithrombotic therapy and follow-up, we developed a dedicated protocol that could be applied in frail patients.

DCBs as an adjuvant tool to DES for very complex coronary lesions.

Drug eluting stents (DES) have revolutionised interventional cardiology and currently represent the standard for percutaneous coronary interventions (PCI). However, due to several limitations, new strategies are required, especially in very complex lesions. Drug-coated balloons (DCB) offer an attractive therapeutic alternative, and have already obtained a Class I recommendation for the treatment of in stent restenosis (ISR) with Level A of evidence.

Should paclitaxel be considered an old generation DCB? The limus era.

Since their introduction Drug Coated Balloons (DCBs) have slowly gained their spot into everyday cath-lab practice, first for treatment of in-stent restenosis (ISR), more recently for small vessels disease; today a growing body of evidence start supporting their use in more complex lesions, from bifurcations, to large vessels, to acute lesions. Although the new generation of DCBs showed a better performance and safety than the older one, the drug of choice has always been the Paclitaxel; last year some concerns were raised on the safety of Paclitaxel devices, in particular the balloons mining their use. Recently Sirolimus ventured in the DCBs world, making its appearance on cath-lab shelves and becoming a good alternative to Paclitaxel (DCB).

Solid Lipid Nanoparticles: Vital Characteristics and Prospective Applications in Cancer Treatment.

Cancer nanotechnology is a new field of interdisciplinary research cutting across biology, chemistry, engineering, and medicine, aiming to lead to major advances in cancer treatment. Over the past several years, solid lipid nanoparticles (SLNs) have attracted the interest of researchers due to their ability to overcome the limitations of classic chemotherapeutics. We reviewed the most recent data on the therapeutic use of SLNs in oncology, presenting their main advantages and disadvantages, along with various production methods and different routes of administration.
