Abstract

Given the potential complications of atrial fibrillation (AF) recurrence after ablation, better predictors of the effectiveness of the procedure are necessary to guide patient selection. This prospective study was conducted to evaluate the clinical relevance of global left atrial longitudinal strain (GLAS) and AF recurrence after catheter ablation. In 115 consecutive patients with AF (persistent, n=62; paroxysmal, n=53), transthoracic echocardiography was performed before catheter ablation to assess baseline left atrial mechanical function using speckle tracking echocardiography (STE). After 12 months of follow-up, 22 (35.5%) patients in the persistent AF group and 15 (28.3%) in the paroxysmal AF group exhibited AF recurrence. In both the paroxysmal and persistent AF populations, patients with recurrence presented with significantly impaired GLAS compared with patients without recurrence. Patients with recurrence also had a significantly higher pro-B-type natriuretic peptide concentration. A receiver operator curve analysis yielded area under the curve values of 0.94 and 0.86 for paroxysmal and persistent AF, respectively. In a multivariable Cox proportional-hazards analysis, GLAS was an independent predictor of AF recurrence a...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
