Key result
Radiofrequency ablation of PVCs and VT originating from the septal right ventricular papillary muscle reduced mean PVC burden from 14% preablation to 0.1% postablation.
Why the study?
Does radiofrequency catheter ablation reduce PVC burden in patients with PVCs/VT originating from the septal right ventricular papillary muscle?
Observational (n=8)
Does radiofrequency catheter ablation reduce PVC burden in patients with PVCs/VT originating from the septal right ventricular papillary muscle?
Absolute Event Rate: 0.1% vs 14%
Radiofrequency ablation is feasible and highly effective at reducing PVC burden in patients with arrhythmias originating from the septal right ventricular papillary muscle.
No takes yet. Share an insight, caveat, or question.
May support ablation for symptomatic septal RV papillary muscle PVCs/VT; hypothesis-generating and requires prospective studies before broader adoption.
Santoro et al. (2014) conducted an observational in Premature ventricular complexes and ventricular tachycardia from the septal right ventricular papillary muscle (n=8). Radiofrequency ablation vs. Preablation baseline was evaluated on Mean PVC burden. Radiofrequency ablation of PVCs and VT originating from the septal right ventricular papillary muscle reduced mean PVC burden from 14% preablation to 0.1% postablation.
