BACKGROUND Implantation of left atrial appendage (LAA) occlusion devices was shown to be a feasible and effective alternative to oral anticoagulation in patients with non-valvular atrial fibrillation. However, only few data about in-hospital and peri-procedural data are currently available. This study aims to report about echocardiographic, procedural and in-hospital data of patients receiving ...

The current real-world anticoagulation practices following left atrial appendectomy in the context of the Maze procedure are unknown. This is a cohort study of all patients who underwent the Maze procedure with amputation of the left atrial appendage from June 2005 to November 2012. Data was prospectively collected at regular intervals with an interview and Holter monitoring. All patients recei...

Introduction The AtriClip left atrial appendage (LAA) exclusion device (AtriCure Inc, Westchester, OH) is a surgical LAA closure device frequently used in conjunction with thoracoscopyguided mini-MAZE surgery to treat atrial fibrillation (AF). It is composed of 2 parallel titanium bars, which provide constant tension when deployed. The AtriClip is coated with polyester fabric, which promotes ti...

The left atrial appendage (LAA) represents one of the major sources of cardiac thrombi responsible for embolic stroke in patients with atrial fibrillation (AF). The aim of the present study was to evaluate LAA structure and functions by transesophageal echocardiography (TEE) in patients with AF to investigate the possible association between the different LAA morphologies and the patients' hist...

Stroke prevention is the primary goal in atrial fibrillation (AF) given its clinical and socioeconomic impact. With AF, the prevalence of thromboembolic stroke continues to rise and there is an urgent need to develop better strategies of stroke prevention. Warfarin, although effective when used appropriately, is burdened by underutilization, narrow therapeutic windows, and life-threatening blee...

Ischemic stroke is a common complication of atrial fibrillation (AF). Currently, oral anticoagulant drugs are the most commonly used method of stroke prevention. Left atrial appendage occlusion is thought to be the main source of thrombi in patients with AF. Percutaneous left atrial appendage is a valuable therapeutic option for selected high-risk patients with AF and contraindications for oral...

The prevalence of atrial fibrillation (AF) is increasing in parallel with an ageing population leading to increased morbidity and mortality. The most feared complication of AF is stroke, with the arrhythmia being responsible for up to 20% of all ischemic strokes. An important contributor to this increased risk of stroke is the left atrial appendage (LAA). A combination of the LAA's unique geome...

Aneurysm of the atrial appendages is an uncommon condition, with few cases described in the literature. These aneurysms are classified into 2 groups: congenital and acquired (mainly secondary to trauma). Those affecting the left atrial appendage, which were first described by Semans and Taussing in 1938, usually manifest in the third and fourth decade of life as tachyarrhythmia refractory to ph...

BACKGROUND Transcatheter left atrial appendage closure is an alternative therapy for stroke prevention in atrial fibrillation patients. These procedures are currently guided with transesophageal echocardiography and fluoroscopy in most centers. As intracardiac echocardiography (ICE) is commonly used in other catheter-based procedures, we sought to determine the safety and effectiveness of intra...
