Fibrilación auricular recurrente posterior a ablación de venas pulmonares: serie de casos

Rev. urug. cardiol; 38 (1), 2023
La ablación de las venas pulmonares se ha convertido en un tratamiento clave para fibrilación auricular (FA). Sin embargo, pueden ocurrir recurrencias. La estrategia disponible para la ablación después de una recurrencia de FA es controvertida, compleja y desafiante, y la información es limitada. Me...

Epicardial Fat Tissue Thickness and Omentin in Patients with Atrial Fibrillation

Abstract Background: Although electrical and structural remodeling has been recognized to be important in the pathophysiology of atrial fibrillation, the mechanisms underlying remodeling process are unknown. There has been increasing interest in the involvement of inflammatory molecules and adipokines r...

Prognostic Prediction of Cardiopulmonary Exercise Test Parameters in Heart Failure Patients with Atrial Fibrillation

Arq. bras. cardiol; 114 (2), 2020
Abstract Background: Atrial fibrillation (AF) is associated with increased mortality in heart failure (HF) patients. Objective: To evaluate whether the risk of AF patients can be precisely stratified by relation with cardiopulmonary exercise test (CPET) cut-offs for heart transplantation (HT) selection...

Dact1 involvement in the cytoskeletal arrangement of cardiomyocytes in atrial fibrillation by regulating cx43

Abstract Objective: To determine the role of the dishevelled binding antagonist of beta catenin 1 (DACT1) in the cytoskeletal arrangement of cardiomyocytes in atrial fibrillation (AF). Methods: The DACT1 expression and its associations with the degree of fibrosis and β-catenin in valvular disease ...

The relationship between mitral annular calcification, metabolic syndrome and thromboembolic risk

Abstract Introduction: Metabolic syndrome (MetS) is defined as an association between diabetes, hypertension, obesity and dyslipidemia and an increased risk of cardiovascular disease. Mitral annular calcification (MAC) is associated with several cardiovascular disorders, including coronary artery diseas...

The factors affecting rhythm control for cryoablation of atrial fibrillation in mitral valve surgery

Abstract Objective: To evaluate the factors impacting on the conversion to sinus rhythm and on the postoperative rhythm findings in the six-month follow-up period of a mitral valve surgery combined with cryoablation Cox-Maze III procedure, in patients with atrial fibrillation. Methods: In this study, w...

Intra-Atrial Dyssynchrony Using Cardiac Magnetic Resonance to Quantify Tissue Remodeling in Patients with Atrial Fibrillation

Arq. bras. cardiol; 112 (4), 2019
Abstract Background: Recent studies suggest that left atrial (LA) late gadolinium enhancement (LGE) can quantify the underlying tissue remodeling that harbors atrial fibrillation (AF). However, quantification of LA-LGE requires labor-intensive magnetic resonance imaging acquisition and postprocessing a...
