INTRODUCTION: Catheter ablation for atrial tachycardia (AT) in Budd-Chiari syndrome (BCS) presents unique challenges due to altered venous anatomy. This case demonstrates an innovative approach to overcome complete inferior vena cava (IVC) occlusion.
METHODS: A 24-year-old female with BCS underwent catheter ablation via an innovative femoral vein-IVC-azygos-SVC approach, guided by preprocedural CT angiography and 3D electroanatomical mapping.
RESULTS: Successful ablation was achieved at the anterior interatrial septum with no arrhythmia recurrence during the 3-month follow-up.
CONCLUSION: This case demonstrates the successful use of an IVC-azygos-SVC approach guided by CT angiography and 3D mapping for atrial tachycardia ablation in Budd-Chiari syndrome, offering a viable solution for patients with complex venous obstruction.
