Embolic strokes of undetermined source comprise a subset of cryptogenic ischemic strokes. It is thought that some embolic strokes of undetermined source could be due to left atrial thromboembolism without atrial fibrillation. The authors sought to determine whether a marker of left atrial pathological changes could pose as a surrogate marker of nonarrhythmogenic atrial thromboembolism in emboli...

INTRODUCTION The aim of the study was to assess the midterm results of left atrial bipolar radiofrequency ablation combined with a mitral valve procedure in patients with mitral valve disease and persistent atrial fibrillation. METHODS Between October 2006 and July 2009, 95 patients with mitral valve disease and persistent atrial fibrillation underwent a mitral valve procedure and left atrial...

Cholinesterase and succinyldehydrogenase activity of surgically removed left atrial auricles from patients in atrial fibrillation and in sinus rhythm have been compared, using histochemical methods. Higher cholinesterase and lower succinyldehydrogenase activity has been found in atrial fibrillation than in sinus rhythm. The pulmonary capillary mean pressure of patients with atrial fibrillation ...

introduction pulmonary vein (pv) isolation is considered as a key to atrial fibrillation (af) treatment. cryoballoon ablation is an effective therapy for pv isolation for af with minimal side effects and was approved by the us food and drug administration (fda) several years ago. successful isolation of pvs during cryoablation depends on the balloon temperature and helps in early identification...

Introduction Atrial fibrillation ablation is an increasingly frequent procedure performed in the electrophysiology laboratory. Pulmonary vein foci account for more than 90% of triggers for atrial fibrillation, most commonly treated with complete pulmonary vein isolation most of the time. Non–pulmonary vein triggers are the drivers of atrial fibrillation in a subgroup of patients. This patient h...

INTRODUCTION Stroke accounts for approx. 90% of thromboembolic complications associated with atrial fibrillation. The use of oral anticoagulants is the most effective therapy but is associated with risk of haemorrhagic complications. AIM In this article, we describe a series of patients with atrial fibrillation, cardiogenic stroke history, and contraindications for long-term anticoagulant the...

OBJECTIVE To determine the effectiveness of surgical isolation of the left atrial posterior wall encompassing the ostia of the pulmonary veins for the treatment of atrial fibrillation of rheumatic etiology. METHODS Prospective and randomized study of patients with rheumatic mitral valve disease, persistent atrial fibrillation for 6 months or longer, age < or = 60 years, and left atrial diamet...
