Key result
Multisite pacing was reported to recruit the disconnected right ventricle and prevent ventricular failure after surgical disconnection for arrhythmia control in ARVC.
Why the study?
Does multisite pacing prevent ventricular failure in patients with ARVC after surgical disconnection of the right ventricle?
Case Report
Does multisite pacing prevent ventricular failure in patients with ARVC after surgical disconnection of the right ventricle?
Multisite pacing may be a viable strategy to restore right ventricular contraction and prevent right ventricular failure following surgical disconnection for refractory ventricular tachycardia in ARVC.
May support multisite pacing after RV disconnection in ARVC; hypothesis-generating and should not yet change practice.
Ventricular tachycardia in ARVC (arrhythmogenic right ventricular cardiomyopathy) is typically managed by ICD implantation, with a limited role of catheter ablation. Surgical disconnection of the right ventricular (RV) has been used to control ventricular tachycardia (VT) in ARVC, but it often led to refractory RV failure due to loss of RV contraction after surgery. We report multisite pacing to recruit the disconnected RV to prevent ventricular failure.

Agarwal et al. (2005) conducted a case report in Arrhythmogenic right ventricular cardiomyopathy (ARVC) with ventricular tachycardia. Multisite pacing was evaluated on Prevention of ventricular failure. Multisite pacing was reported to recruit the disconnected right ventricle and prevent ventricular failure after surgical disconnection for arrhythmia control in ARVC.
