Abstract

Concomitant surgical ablation for atrial fibrillation (AF) at the time of mitral valve surgery is a Society of Thoracic Surgeons Class IA recommendation with evidence from randomized trial data. We hypothesized that concomitant AF ablation rates have increased over time with implementation of this evidence-based practice. All patients (N = 7261) undergoing mitral valve operations (2011-2018) were queried from a regional Society of Thoracic Surgeons database. Patients with preoperative AF were stratified by concomitant AF ablation. Trends in concomitant ablation were evaluated over time as well as by center and surgeon mitral surgical volume. The associations between patient and center factors on implementation of concomitant ablation were assessed with multivariate regression. A total of 1675 patients with preoperative AF underwent isolated mitral valve operations, with 1044 (64.6%) undergoing concomitant ablation. The utilization of concomitant ablation decreased over the study period (-2.82%/year), and was strongly associated with surgeon mitral valve volume (high 78.2% vs medium 62.5% vs low 59.0%; P < .001). Multivariate regression demonstrated age and comorbidities were strong predictors, but high volume mitral surgeons (o...Continue Reading

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.

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.
