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.
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.
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.
Congenital inferior vena cava (IVC) anomalies, including azygos continuation, can complicate catheter-based interventions such as ablation of atrioventricular nodal reentrant tachycardia.Congenital anomalies of IVC are rare but critical considerations for atrioventricular nodal reentry tachycardia (AVNRT) ablation procedures.Understanding these variations is essential for ensuring successful catheter-based interventions and minimizing the risk of complications.
下腔静脉（IVC）的先天性异常，如中断或奇静脉延续，会使诸如房室结折返性心动过速（AVNRT）消融等基于导管的手术变得复杂。了解IVC变异对于介入心脏病学的成功治疗结果至关重要。
一名患有长期阵发性心房颤动（AF）的57岁男性成功接受了AVNRT导管消融术。术中发现先天性IVC异常，需要改进血管入路。
识别IVC异常并调整入路策略是克服手术挑战并确保消融成功的关键。全面的影像学检查和规划对于处理有IVC变异的患者至关重要。
先天性下腔静脉（IVC）异常，包括奇静脉延续，会使诸如房室结折返性心动过速消融等基于导管的干预措施变得复杂。IVC先天性异常罕见，但对于房室结折返性心动过速（AVNRT）消融手术是关键的考虑因素。了解这些变异对于确保基于导管的干预成功并将并发症风险降至最低至关重要。
