Key result
Catheter ablation of post-surgical atrial tachycardia after mitral valve surgery restored sinus rhythm in 96% of patients, with prior Cox-Maze IV predicting left-sided arrhythmia (OR 17.3).
Why the study?
Data regarding catheter ablation of post-surgical atrial tachycardia occurring after mitral valve surgery were scarce.
Is catheter ablation feasible and safe for treating post-surgical atrial tachycardia after mitral valve surgery?

Supports ablation feasibility after mitral surgery; hypothesis-generating and requires prospective trials before practice change.
Systematic Review (n=206)
Is catheter ablation feasible and safe for treating post-surgical atrial tachycardia after mitral valve surgery?
Odds Ratio: 17.3 (95% CI 7.2–41.2)
p-value: p=<0.0001
Catheter ablation of atrial tachycardia after mitral valve surgery is highly feasible and safe, with prior Cox-Maze IV procedure strongly predicting left-sided arrhythmias.
Marazzato et al. (2021) conducted a systematic review in Post-surgical atrial tachycardia after mitral valve surgery (n=206). Catheter ablation was evaluated on Left-sided arrhythmia (OR 17.3, 95% CI 7.2-41.2, p=<0.0001). Catheter ablation of post-surgical atrial tachycardia after mitral valve surgery restored sinus rhythm in 96% of patients, with prior Cox-Maze IV predicting left-sided arrhythmia (OR 17.3).
