Overview

Highlights need to screen for venous anomalies in refractory cases; extends associations and leaves causality open to further study.

Key Points

  • To explore the risks associated with interrupted inferior vena cavae and duplicated superior vena cavae during catheter ablation.
  • Identified congenital venous anomalies during catheter ablation procedures.
  • Reviewed patient symptoms related to thromboembolic events and arrhythmias.
  • Recommended advanced imaging to investigate unexplained clinical presentations.
  • Patients with interrupted IVCs faced higher thromboembolic risks.
  • Duplicated SVCs were associated with increased episodes of arrhythmias.
  • Prompt diagnosis of these anomalies can improve patient outcomes.

Structured PICO

P
Population
Patients with congenitally interrupted inferior vena cava (IVC) and duplicated superior vena cavae (SVC)
I
Intervention
Catheter ablation and advanced imaging

Venous anomalies such as interrupted IVC and duplicated SVC should be considered in patients with unexplained or refractory thromboembolic events and arrhythmias.

Cite This Study

Rigden et al. (2026) studied this question. Interrupted IVCs and duplicated SVCs may increase thromboembolic and arrhythmic risks, warranting advanced imaging for unexplained or refractory symptoms.
