Key result
Noninvasive surface mapping yields 95% diagnostic accuracy for atrial arrhythmias and facilitates successful catheter ablation.
Why the study?
Does surface electrocardiographic mapping accurately diagnose and facilitate catheter ablation of atrial arrhythmias in patients after mitral valve surgery?
Observational (n=43)
No
Does surface electrocardiographic mapping accurately diagnose and facilitate catheter ablation of atrial arrhythmias in patients after mitral valve surgery?
Noninvasive surface ECG mapping provides high diagnostic accuracy (95%) for atrial arrhythmias after mitral valve surgery, facilitating effective catheter ablation.
May support noninvasive mapping for post-mitral valve atrial arrhythmias; leaves open need for randomized confirmation.

Kvasha et al. (2020) conducted an observational in Complex atrial arrhythmias after mitral valve surgery (n=43). Surface noninvasive electrocardiographic mapping and catheter ablation was evaluated on Diagnostic accuracy of electrocardiographic surface mapping. Surface noninvasive electrocardiographic mapping demonstrated a 95% diagnostic accuracy for atrial arrhythmias and facilitated catheter ablation that achieved stable sinus rhythm in 81.4% of cases after one procedure.
