Atrial fibrillation (AF) is an arrhythmia associated with functional and morphological remodeling of atria. We investigated the distribution and the expression of connexins in atrial tissues from patients with chronic AF and left atrial dilatation (AD). Immunohistochemistry was performed in atrial tissues obtained during cardiac surgery from patients with chronic ...

Atrial fibrillation is often highly symptomatic in patients with hypertrophic cardiomyopathy. In the present paper we describe the results of circumferential pulmonary vein ablation in two such patients. Although multiple antiarrhythmic drugs failed to prevent recurrences of AF in each patient, catheter ablation resulted in long-term maintenance of sinus rhythm ...

Background: The electrophysiological mechanisms underlying atrial fibrillation (AF) are incompletely understood. Experimental studies have shown that remodelling of the atrial myocardium is linked to the occurrence and perpetuation of AF. Interatrial conduction disturbances and also delayed conduction at the posteroparaseptal region have also been reported as potential arrhythmogenic substrates. However, ...

Fibrin D-dimers levels have been advocated as a useful clinical marker of thrombogenesis. It is accepted that patients with atrial fibrillation (AF) are characterized by increased levels of plasmatic d-dimers. AF is a high risk factor for hypercoagulability, with a substantial risk of thromboembolism. The most effective way of minimizing ...

INTRODUCTION: Pulmonary vein (PV) stenosis is an important complication of the AF ablation and could be underestimated if their assessment is not systematically done. Selective Segmental Ostial Ablation (SSOA) and Circunferential Pulmonary Veins Ablation (CPVA) have demonstrated efficacy in atrial fibrillation (AF) treatment. In this study the real incidence of ...
