Abstract Objective: To assess heart rhythm and predictive factors associated with sinus rhythm after one year in patients with rheumatic valve disease undergoing concomitant surgical treatment of atrial fibrillation. Operative mortality, survival and occurrence of stroke after one year were also evaluat...
Abstract INTRODUCTION: Left atrial ganglionated plexi ablation is an adjuvant technique used to increase the success rate of surgical ablation of atrial fibrillation. Ganglionated plexi ablation requires previous detection. We aimed to assess determinants of successful ganglionated plexi detection and t...
Abstract Background: Atrial electromechanical delay (EMD) is used to predict atrial fibrillation, measured by echocardiography. Objectives: The aim of this study was to assess atrial EMD and mechanical function after anthracycline-containing chemotherapy. Methods: Fifty-three patients with breast canc...
Abstract Background: Atrial fibrillation (AF) is the most common arrhythmia seen in adults. Atrial stunning is defined as the temporary mechanical dysfunction of the atrial appendage developing after AF has returned to sinus rhythm (SR). Objectives: We aimed to evaluate atrial contractile functions by ...
Fundamento: Existem marcadores eletrocardiográficos para predição de fibrilação atrial (FA) na prática clínica, mas não há consenso sobre sua real utilidade. O desenvolvimento de novos marcadores pode ser uma alternativa para melhorar a predição de FA. Este estudo tem o objetivo de demonstrar ...
Fundamentos: Diabéticos hipertensos apresentam maior probabilidade de desenvolverem hipertrofia ventricular esquerda e fibrilação atrial. Evidências sugerem que bloqueadores do sistema renina-angiotensina-aldosterona devem ser usado neste grupo de pacientes. Objetivo: Avaliar se há diferença entr...
OBJECTIVES: This study investigated whether the serum matrix metalloproteinase-9 level is an independent predictor of recurrence after catheter ablation for persistent atrial fibrillation. METHODS: Fifty-eight consecutive patients with persistent atrial fibrillation were enrolled and underwent catheter ...
Se realiza un análisis sobre la prevalencia de la fibrilación auricular en la población general y en pacientes que presentan algunas enfermedades asociadas. Se comenta sobre las posibles teorías fisiopatológicas de esta enfermedad y se abarcan las diferentes técnicas quirúrgicas que se aplican sob...
