Summary
Concomitant surgical atrial fibrillation (AF) ablation alongside cardiac surgery achieved freedom from AF in 50.9% of patients. A new scoring system effectively predicts successful return to sinus rhythm post-procedure.
Area of Science:
- Cardiology
- Cardiac Surgery
- Electrophysiology
Background:
- Radiofrequency ablation for atrial fibrillation (AF) can be combined with cardiac surgery.
- This approach risks longer bypass times and sinoatrial node damage.
- Efficacy of concomitant surgical AF ablation requires further assessment.
Purpose of the Study:
- To evaluate the effectiveness of concomitant surgical AF ablation.
- To develop a novel scoring system for predicting post-procedural sinus rhythm.
- To identify predictors of successful AF ablation during cardiac surgery.
Main Methods:
- Retrospective review of 76 patients undergoing cardiac surgery with concomitant AF ablation (Jan 2012 - Dec 2013).
- Data collection via patient notes, clinic letters, and echocardiography.
- Development and validation of a novel scoring system using ROC curve analysis.
Main Results:
- At median follow-up (383 days), 50.9% of patients were free from AF.
- The novel scoring system demonstrated good predictive accuracy for return to sinus rhythm (ROC AUC = 0.7708).
Conclusions:
- A novel scoring system can predict procedural success for concomitant AF ablation during cardiac surgery.
- The scoring system aids in patient selection and outcome prediction.
- Further validation in larger cohorts is recommended.
