The DEFINITION (Impact of the complexity of bifurcation lesions treated with drug-eluting stents) study has provided a novel classification to evaluate the complexity of coronary bifurcation lesion according to coronary angiography, but angiographic imaging due to its low resolution and inherited limitation may result in an inaccurate adjudication.We used optical coherence tomography (OCT) to further evaluate the coronary characteristics in a patient with "simple" bifurcation lesion which was classified by the DEFINITION criteria...

Bifurcation lesions represent one of the most challenging lesions subset in interventional cardiology. The European Bifurcation Club (EBC) is an academic consortium whose goal has been to assess and recommend the appropriate strategies to manage bifurcation lesions. The quantitative coronary angiography (QCA) methods for the evaluation of bifurcation lesions has been subject to extensive research. Single vessel quantitative coronary angiography (QCA) has shown to be inaccurate to assess bifurcation lesions dimensions...

BACKGROUND: The presence of a bifurcation (BL) in the context of a coronary chronic total occlusion (CTO) represents an additional difficulty. This study analyzes the incidence of BLs in CTO recanalization, the treatment, predictors of bifurcation technical success and their clinical impact. METHODS AND RESULTS: BLs with a side branch (SB) ≥2.0mm located proximally, distally or within the occluded segment were observed in 130 (33%) of 391 CTO. Provisional stenting was the strategy more frequently used (94%)...

In this paper we derive a reaction-diffusion-chemotaxis model for the dynamics of multiple sclerosis. We focus on the early inflammatory phase of the disease characterized by activated local microglia, with the recruitment of a systemically activated immune response, and by oligodendrocyte apoptosis. The model consists of three equations describing the evolution of macrophages, cytokine and apoptotic oligodendrocytes. The main driving mechanism is the chemotactic motion of macrophages in response to a chemical gradient provided by the cytokines...

BACKGROUND: The study aimed to report the results from an all-comers registry of patients undergoing coronary angioplasty and treated with bioresorbable vascular scaffold (BVS). METHODS: Fifty-five consecutive patients with type B/C coronary lesions according to the AHA classification and treated with BVS were enrolled in the study. The clinical and procedural characteristics of enrolled patients were recorded. Fifty-five consecutive subjects with coronary lesions type B/C treated with everolimus eluting stent (EES) were used as control group...

BACKGROUND AND PURPOSE: Spreading depolarizations (SDs) may contribute to delayed cerebral ischemia after subarachnoid hemorrhage (SAH). We tested whether SD-inhibitor valproate reduces brain injury in an SAH rat model with and without experimental SD induction. METHODS: Rats were randomized in a 2×2 design and pretreated with valproate (200 mg/kg) or vehicle for 4 weeks. SAH was induced by endovascular puncture of the right internal carotid bifurcation. One day post-SAH, brain tissue damage was measured with T2-weighted magnetic resonance imaging, followed by cortical application of 1 mol/L KCl (to induce SDs) or NaCl (no SDs)...

Coronary artery bypass grafting (CABG) decreases mortality in patients with significant left main (LM) coronary artery disease and for years remained the therapy of choice for patients with this ominous lesion. Advances in percutaneous coronary intervention (PCI) have enabled it to become an alternative to CABG. The results of observational registries and randomized comparisons have shown the safety and efficacy of PCI in appropriately selected patients with low or intermediate angiographic risk scores. Furthermore, the use of physiological measures of flow limitation and the use of intracoronary imaging techniques has added benefit and improved outcomes...

The role of final kissing balloon (FKB) inflation after simple crossover stenting in unprotected left main (LM) bifurcation stenosis remains unknown. From the Asan Medical Center-Left Main Revascularization (ASAN-MAIN) registry, 413 patients with LM bifurcation stenosis treated by simple crossover stenting with a drug-eluting stent were identified. After simple crossover stenting, FKB inflation was performed in 95 patients (FKB group) and 318 patients finished the procedure without FKB (no-FKB group). The primary end points of the 2-year incidence of major adverse cardiac events (death, myocardial infarction, and left main target lesion revascularization [LM-TLR]) were similar between the FKB and no-FKB groups (12...

BACKGROUND: It is very difficult to deal with the comprehensive central airway diseases, especially the malignant airway obstruction. The aim of this study is to explore the clinical effects of multiple interventional bronchoscopies for the treatment of 112 cases with comprehensive malignant central airway diseases so as to evaluate the clinical applications of thermoablation and cryosurgery. METHODS: The 112 cases with malignant airway diseases retrospectively reviewed for bronchoscopic interventions performed in more than two lesions of carina and/or bifurcation...
