Is epicardial substrate ablation safe and effective for treating ventricular tachycardia in patients late after myocarditis?
An epicardial approach using unipolar mapping and substrate modification is safe and effective for ablating ventricular tachycardia in patients with prior myocarditis.
Pre-procedural scar imaging and EAM findings support the necessity of an epicardial approach in patients with prior myocarditis. Epicardial unipolar mapping (<8 mV) is superior in scar identification and CA based on substrate modification is safe and effective in this setting.
