This study describes a new approach for SVC isolation, which involves creating a C-shaped non-circumferential ablation line to reduce complications. The results showed that this method was effective, but larger studies and long-term follow-up are still needed to confirm these findings.
IntroductionSuperior vena cava (SVC) isolation has been proposed as part of the ablation strategy for atrial fibrillation. However, circumferential isolation of the SVC can lead to late-onset complications, such as SVC stenosis.MethodsWe describe a detailed observation of the SVC conduction pattern and present a newly developed approach for SVC isolation that involves creating a C-shaped non-circumferential ablation line while sparing the lateral segment.ResultsTwelve consecutive patients were included in the study, all of whom achieved bidirectional block during the ablation procedure.DiscussionThis approach to SVC isolation is effective and has the potential to reduce ablation related complications; however, larger studies and long-term follow-up is warranted to confirm these findings.
