introduction atrial standstill is a rare condition, characterized by absence of atrial electrical and mechanical activity evident in surface electrocardiography echocardiography, or fluoroscopy, which is associated with unresponsiveness of atria to maximal output electrical stimulation. this condition can be present with thromboembolic complication, low cardiac output, and sometimes palpitation...

Introduction Atrial arrhythmia is common in patients with an atrial septal defect (ASD). Atrial fibrillation (AF) is the main cause of morbidity in older patients with ASD. An unroofed coronary sinus (CS) is rare (in,1% of all types of ASD) and is often associated with persistent left superior vena cava (PLSVC) and other forms of complex congenital heart disease and heterotaxy syndromes. Unroof...

The Cox maze III and Cox maze IV procedures are surgical solutions for the treatment of symptomatic stand-alone atrial fibrillation. Despite their proven efficacy, these procedures have not gained widespread acceptance because of the invasiveness, complexity, and technical difficulty. Endocardial pulmonary vein isolation is the cornerstone of percutaneous catheter ablation for atrial fibrillati...

Atrial fibrillation is the most common sustained arrhythmia and is associated with significant risks of thromboembolism, stroke, congestive heart failure, and death. There have been major advances in the management of atrial fibrillation including pharmacologic therapies, antithrombotic therapies, and ablation techniques. Surgery for atrial fibrillation, including both concomitant and stand-alo...

Background: Catheter and cryoballoon ablation are established treatments for atrial fibrillation. Frequently, substrate modification of the left atrium is performed in patients with persistent AF or evidence of left atrial adverse remodeling. We compared one year outcomes of AF ablation with substrate modification utilizing radiofrequency catheter ablation (RFA) compared to a combination of cry...

BACKGROUND We evaluated the safety and effectiveness of the hybrid thoracoscopic endocardial epicardial technique for the treatment of lone atrial fibrillation. METHODS Between 2009 and 2012, a cohort of 78 consecutive patients (median age 60.5 years, 77% male) underwent ablation of atrial fibrillation (AF) as a stand-alone procedure using a thoracoscopic, hybrid epicardial-endocardial techni...
