Significant improvement of left atrial and left atrial appendage function after catheter ablation for persistent atrial fibrillation.
BACKGROUND The long-term effects of catheter ablation (CA) on the left atrium and left atrial appendage (LAA) are unknown in persistent atrial fibrillation (AF). This study investigated left atrial (LA) reverse remodeling and evolution of LA/LAA function after successful CA for persistent AF and identified predictors for maintenance of sinus rhythm (SR) and LA reverse remodeling. METHODS AND ...
متن کاملA Semi-Automated Algorithm for Segmentation of the Left Atrial Appendage Landing Zone: Application in Left Atrial Appendage Occlusion Procedures
Background: Mechanical occlusion of the Left atrial appendage (LAA) using a purpose-built device has emerged as an effective prophylactic treatment in patients with atrial fibrillation at risk of stroke and a contraindication for anticoagulation. A crucial step in procedural planning is the choice of the device size. This is currently based on the manual analysis of the “Device Landing Zone” fr...
متن کاملLeft atrial strain predicts recurrence of atrial arrhythmias after catheter ablation of persistent atrial fibrillation
INTRODUCTION Success rates of catheter ablation (CA) of persistent atrial fibrillation (AF) are very variable. Identifying patients in whom sinus rhythm maintenance cannot be achieved after CA is a critical issue. METHODS 2D speckle-tracking echocardiography was performed before the first CA procedure in consecutive patients with persistent AF. Left atrial (LA) strain was correlated with recu...
متن کاملPercutaneous interventions in elderly patients with atrial fibrillation: left atrial ablation and left atrial appendage occlusion
Heart rhythm disturbances become of special importance when patients reach a senior age. Atrial fibrillation (AF) is the most prevalent arrhythmia among the old age groups, and its impact on morbidity and mortality becomes of paramount significance. In this population, AF is responsible for significant amount of thromboembolic cerebrovascular events, especially for disabling and fatal strokes. ...
متن کاملImprovement of left atrial function and left atrial reverse remodeling after surgical treatment of atrial fibrillation.
Two-dimensional speckle tracking echocardiography (2D-STE) is an emerging technology for the evaluation of left atrial (LA) function. This technique is feasible, overcomes the limitations of tissue Doppler imaging and has been demonstrated to accurately assess atrial function during the different phases of the cardiac cycle (1). Atrial structural and electrical remodeling are the hallmarks of a...
