Abstract

Background: Congenital anomalies of the inferior vena cava (IVC), such as interrupted or azygos continuation, complicate catheter-based procedures like atrioventricular nodal reentrant tachycardia (AVNRT) ablation. Understanding IVC variations is crucial for successful outcomes in interventional cardiology.
Case presentation: A 57-year-old male with long-standing paroxysmal atrial fibrillation (AF) underwent successful catheter ablation for AVNRT. Intra-procedurally, a congenital IVC anomaly was identified, requiring modified vascular access.
Conclusion: Recognizing IVC anomalies and adapting access strategies are key to overcoming procedural challenges and ensuring successful ablation outcomes. Comprehensive imaging and planning are vital for managing patients with IVC variations.
