Upside-down 3-dimensional mapping technique for catheter ablation via the superior vena cava in a patient with inferior vena cava interruption
Inferior vena cava (IVC) anomalies, including left-sided IVC, duplicated IVC, and IVC interruption with azygos continuation, are often incidentally detected during electrophysiological studies and can complicate catheter manipulation during ablation. The internal jugular vein approach, which reverses catheter manipulation compared with the standard approach, is often required in cases of IVC interruption.
