Key result
Radiofrequency catheter ablation for electrical isolation of the superior vena cava can cause SVC stenosis, suggesting noncircumferential lesion sets may be preferred.
Why the study?
Does radiofrequency catheter ablation for electrical isolation of the superior vena cava cause SVC stenosis?
Does radiofrequency catheter ablation for electrical isolation of the superior vena cava cause SVC stenosis?
Radiofrequency catheter ablation for electrical isolation of the superior vena cava can result in SVC stenosis, suggesting that noncircumferential lesion sets may be preferred.
Raises caution for SVC stenosis after isolation; leaves open optimal lesion strategy in prospective studies.
Ectopic beats originating from the superior vena cava (SVC) may initiate atrial fibrillation. This report describes a patient undergoing radiofrequency catheter ablation for electrical isolation of the SVC resulting in SVC stenosis. Noncircumferential lesion sets for SVC isolation to reduce ablation times may be preferred. (PACE 2010; e36-e38).
