Why the study?
Does radiofrequency isolation of the inferior vena cava prevent arrhythmias in a patient with parasystole originating from the IVC?
Does radiofrequency isolation of the inferior vena cava prevent arrhythmias in a patient with parasystole originating from the IVC?
Radiofrequency isolation of the inferior vena cava can successfully and durably treat parasystole originating from the IVC ostium.
May support durable control of IVC-origin parasystole; leaves open need for prospective studies before wider adoption.
A 76-year-old man with a history of atrial septal defect repair underwent radiofrequency (RF) ablation of typical atrial flutter. During electrophysiological study, incessant sharp potentials were recorded, originating from the ostium of the inferior vena cava (IVC), and dissociated from atrial activity. During sinus rhythm, these potentials propagated to the atria and caused premature complexes when falling beyond the atrial refractory period. Electro-anatomical mapping revealed the presence of the earliest potential in the postero-lateral ostium of the IVC, propagating to the septal region. After RF isolation of the IVC, the patient has remained arrhythmia-free over a 5-year follow-up.
