Key result
Radiofrequency catheter ablation of papillary muscle PVCs eliminated triggers in all 6 patients, resulting in 0% recurrence of symptomatic ventricular arrhythmias over a mean follow-up of 58 months.
Why the study?
Does radiofrequency catheter ablation prevent recurrent ventricular fibrillation in patients with VF triggered by papillary muscle PVCs?
Observational (n=6)
Does radiofrequency catheter ablation prevent recurrent ventricular fibrillation in patients with VF triggered by papillary muscle PVCs?
Radiofrequency ablation of papillary muscle PVCs triggering VF is feasible and effective in preventing recurrent VF in patients with structurally normal hearts or nonischemic cardiomyopathy.
No takes yet. Share an insight, caveat, or question.
May support ablation for papillary muscle PVC-triggered VF; hypothesis-generating from small case series, needs prospective validation.
Santoro et al. (2014) conducted an observational in Ventricular fibrillation triggered by papillary muscle PVCs (n=6). Radiofrequency catheter ablation was evaluated on Recurrence of symptomatic ventricular arrhythmias. Radiofrequency catheter ablation of papillary muscle PVCs eliminated triggers in all 6 patients, resulting in 0% recurrence of symptomatic ventricular arrhythmias over a mean follow-up of 58 months.
