Atrial fibrillation (AF), the most common cardiac arrhythmia, is a major risk factor for thromboembolic events, especially ischemic stroke. Catheter ablation is an effective method to maintain sinus rhythm in patients with AF. Although some observational studies have shown a relatively lower stroke rate after catheter ablation, whether catheter ablation can reduce the thromboembolic risk in patients with AF remains unclear. We aim to perform a systematic review to determine whether catheter ablation can prevent thromboembolism in patients with AF...

BACKGROUND: Although the Woven EndoBridge (WEB, Sequent Medical, Aliso Viejo, California, USA) is a highly innovative technique for the endovascular treatment of wide-necked bifurcation aneurysms, there are no studies available comparing this technique to surgical results are other endovascular results of stent assisted coiling or balloon assisted coiling for wide necked aneurysms. OBJECTIVE: This study was to assess complications, complete occlusion rate and morbidity and mortality of WEB in WNBA treatment...

OBJECTIVE: To compare contrast-enhanced MR angiography (CE-MRA) and DSA for the follow-up of intracranial aneurysms (IAs) treated with the Woven EndoBridge embolization system DL (WEB DL; Sequent Medical, Aliso Viejo, California, USA). MATERIALS AND METHODS: We retrospectively identified all patients treated with a WEB DL between November 2010 and February 2013 in 2 hospitals. The IA occlusion was graded on follow-up CE-MRA and DSA by 4 independent readers and by 2 readers reaching a consensus, respectively...

BACKGROUND AND PURPOSE: WEBCAST is a European study dedicated to the evaluation of the feasibility, safety, and efficacy of endovascular treatment with WEB of intracranial aneurysms. MATERIALS AND METHODS: The study was conducted in 10 European centers. Inclusion criteria were aneurysms located at internal carotid artery bifurcation, middle cerebral artery, basilar artery, and anterior communicating artery with a neck ≥4 mm and a dome to neck ratio ≥ 1. Recanalized aneurysms were not included...

BACKGROUND AND PURPOSE: Flow disruption with the WEB-DL device has been used safely for the treatment of wide-necked bifurcation aneurysms but the stability of aneurysm occlusion after this treatment is unknown. This retrospective multicenter European study analyzed short- and midterm data in patients treated with WEB-DL. METHODS: Twelve European neurointerventional centers participated to the study. Clinical data, pre- and post-operative, short-, and midterm images were collected...

OBJECTIVE: The WEB (WEB aneurysm embolization system, Sequent Medical, Aliso Viejo, California, USA) is a self-expanding, nitinol, mesh device designed to achieve aneurysm occlusion after endosaccular deployment. The WEB Occlusion Scale (WOS) is a standardized angiographic assessment scale for reporting aneurysm occlusion achieved with intrasaccular mesh implants. This study was performed to assess the interobserver variability of the WOS. METHODS: Seven experienced neurovascular specialists were trained to apply the WOS...

INTRODUCTION: The Woven Endobridge (WEB II) device (Sequent Medical, Inc., Aliso Viejo, CA, USA) is an intra-saccular, oblate, braided-wire embolization device designed to provide flow disruption at the aneurysm neck-parent artery interface. The purpose of this study was to evaluate the acute and short-term performance of the WEB II device regarding the immediacy, degree, and durability of aneurysm occlusion in two patients. METHODS: The WEB II device was implanted in one patient with an unruptured MCA trifurcation aneurysm and one patient with an unruptured basilar tip aneurysm...
