SUOH 03 Guidewire for the Management of Coronary Artery Dissection: Insights from a Multicenter Registry.

Background: In the setting of coronary artery dissection, both spontaneous and iatrogenic, fixing the intimal tear, usually with stent implantation, can be extremely challenging if the distal wire position has been lost. Common complications are mainly related to the inadvertent subintimal tracking of the guidewire while attempting to gain the distal true lumen.

Aims: To report the registry results of using the SUOH 0.

Radial artery occlusion after transradial procedures: impact on 1-year adverse events.

Background: Radial artery occlusion after transradial procedures is a frequent iatrogenic thrombotic process. The impact on prognosis has not been investigated. This study sought to investigate whether radial artery occlusion is related to increased risk of major adverse cardiac and cerebrovascular events, defined as death, myocardial infarction, stroke and coronary revascularization.

One-Month Dual Antiplatelet Therapy After Bioresorbable Polymer Everolimus-Eluting Stents in High Bleeding Risk Patients.

Background It is unknown whether contemporary drug-eluting stents have a similar safety profile in high bleeding risk patients treated with 1-month dual antiplatelet therapy following percutaneous coronary interventions. Methods and Results We performed an interventional, prospective, multicenter, single-arm trial, powered for noninferiority with respect to an objective performance criterion to evaluate the safety of percutaneous coronary interventions with Synergy bioresorbable-polymer everolimus-eluting stent followed by 1-month dual antiplatelet therapy in patients with high bleeding risk. In case of need for an oral anticoagulant, patients received an oral anticoagulant in addition to a P2Y inhibitor for 1 month, followed by an oral anticoagulant only.

Radial artery occlusion after conventional and distal radial access: Impact of preserved flow and time-to-hemostasis in a propensity-score matching analysis of 1163 patients.

Objectives: To compare incidence of forearm radial artery occlusion (RAO) and hemostasis characteristics between distal and conventional transradial approach (DRA and TRA, respectively).

Background: DRA has the potential advantage of reducing RAO. DRA effectively reduces time-to-hemostasis, however its role on preserving flow in the radial artery (PF) during hemostasis and consequent impact on RAO remains speculative.

Transradial artery access for percutaneous cardiovascular procedures: state of the art and future directions.

The transradial access (TRA) for cardiac catheterization and percutaneous coronary intervention (PCI) has been widely adopted in the last decades since its first description in the late 40s. The transradial approach has been associated with favorable outcomes as compared with transfemoral access (TFA) in several registries and randomized clinical trials, mainly due to the lower incidence of access-site bleedings, vascular complications and improved patient comfort. This review aimed to summarize the body of evidence supporting the use of TRA, to discuss clinical implications, possible technical limitations and future directions, such as the implementation of TRA as the primary access for complex procedures and structural interventions.

Exposure to glyphosate during pregnancy induces neurobehavioral alterations and downregulation of Wnt5a-CaMKII pathway.

Glyphosate-based formulations are the most popular herbicide used around the world. These herbicides are widely applied in agriculture to control weeds on genetically modified crops. Although there is much evidence showing that glyphosate-based herbicides induce toxic effect on reproductive and hepatic systems, and also cause oxidative damage on cells, studies from recent years revealed that the nervous system may represent a key target for their toxicity.

Predictors of patent and occlusive hemostasis after transradial coronary procedures.

Objectives: To assess the independent predictors of patent and occlusive hemostasis (PH and OH, respectively) during radial hemostasis after coronary procedures.

Background: Radial artery occlusion (RAO) is a thrombotic complication of transradial catheterization that can lead to permanent occlusion of the radial artery. Sheath-vessel diameter ratio, postprocedure compression time, occlusive hemostasis, inadequate, and excessive anticoagulation are all predictors of RAO.

Social Isolation in Male Rats During Adolescence Inhibits the Wnt/β-Catenin Pathway in the Prefrontal Cortex and Enhances Anxiety and Cocaine-Induced Plasticity in Adulthood.

In adult animals, it is well established that stress has a proactive effect on psychostimulant responses. However, whether only a short period of stress during adolescence can also affect cocaine responses later in life and what mechanisms are involved are unknown. Here, we showed that 5 days of social isolation during rat adolescence had a long-term impact on anxiety-like behaviors, cocaine-induced conditioned place preference, and the expression of sensitization during adulthood.

Long-Term Outcomes of Coronary and Carotid Artery Disease Revascularization in the FRIENDS Study.

Objectives: The aim of this study is to assess long-term-outcomes of patients with concomitant CAD and COD treated with different revascularization strategies.

Background: Multisite artery disease is common and patients with combined disease have poor prognosis. The best therapeutic strategy for patients with concomitant carotid obstructive disease (COD) and coronary artery disease (CAD) remains controversial.

[Endovascular treatment of symptomatic carotid artery dissection].

Internal carotid artery dissection is one of the possible causes of stroke in young adults. The effectiveness of medical therapy alone is often limited and endovascular strategy should be considered, particularly in the presence of persisting neurological symptoms. Currently, there is no general consensus on the most appropriate therapeutic strategy to follow in symptomatic carotid artery dissection.

Optical coherence tomography assessment of newgeneration mesh-covered stents after carotid stenting.

Aims: The aim of this study was to identify the findings (by optical coherence tomography [OCT]) after carotid artery stenting (CAS) with two different types of new-generation mesh-covered stent.

Methods And Results: Sixteen consecutive patients undergoing CAS with mesh-covered stents and highdefinition OCT image acquisition were enrolled in the study. Cross-sectional OCT images for the presence of strut malapposition (SM) and plaque prolapse (PP) were evaluated using a proximal or distal embolic protection device (EPD).

Drug-coated balloon: Long-term outcome from a real world three-center experience.

Objectives: In-stent restenosis (ISR) and diffuse small vessel disease still represent challenging subsets for percutaneous coronary interventions, also in the new-generation DES era. We aim at reporting on the long-term clinical outcome of drug-coated balloons (DCB) in all-comers population.

Methods: Consecutive patients treated with DCB between January 2011 and December 2014 were retrospectively studied in three centers of northern Italy.

Independent Modular Filter for Embolic Protection in Carotid Stenting.

Background: Embolic protection during carotid artery stenting reduces the rate of thromboembolic events. The Wirion Embolic Protection System is used to deploy an independent distal filter using any 0.014″ guidewire.

A New Strategy for Transcatheter Left Atrial Appendage Closure With Cerebral Embolic Protection in Patient With Left Auricular Thrombosis and Total Contraindication to Long-Term Anticoagulation.

Atrial fibrillation (AF) is the most common cardiac arrhythmia, occurring in 1%-2% of the general population. An important aspect is the treatment of AF in terms of stroke prevention. In patients with absolute contraindication to long-term anticoagulation due to high bleeding risk, a valuable alternative exists in left atrial appendage (LAA) closure.

Recent developments of imaging modalities of carotid artery stenting.

Compared with conventional angiogram-guided procedure, intravascular imaging modalities give us a lot of useful information to make the procedure better. Intravascular imaging modalities give us the information about lesion characters, reference vessel diameter and the interaction between the stent strut and the plaque such as stent strut malapposition or plaque prolapse in real time during the procedure. We can change our strategy according to this information.

Update on new stents and protection devices for carotid artery stenting: what we know, what we learnt recently and what we need to know.

Carotid artery stenting (CAS) is considered an alternative option to carotid endarterectomy (CEA) for significant carotid stenosis, in both symptomatic and asymptomatic patients. Comparing to CEA, CAS offers significant advantages. The most important arise from the minimally invasive nature of the procedure, which reduces the surgical complications and adds significant comfort to the patient, without compromising the efficacy.
