Insights
Persistent left superior vena cava (LSCV) with absent right SVC is rare. Pacemaker implantation via LSCV and coronary sinus is a safe and effective strategy for patients with this anomaly.
Area of Science:
- Cardiology
- Anatomical Variations
- Medical Devices
Background:
- Persistent left superior vena cava (PLSC) with absent right SVC is a rare congenital anomaly.
- This anatomical variation presents unique challenges for cardiovascular interventions, particularly permanent pacemaker implantation.
Observation:
- The study reports on three patients diagnosed with PLSC and absent right SVC.
- These patients required permanent pacemaker implantation due to cardiac conditions.
Findings:
- Successful permanent pacemaker implantation was achieved in all three patients.
- The implantation utilized the persistent left superior vena cava and the coronary sinus as access routes.
- No acute or chronic complications were observed post-implantation.
Implications:
- This approach demonstrates the feasibility and safety of transvenous pacemaker implantation in patients with this rare anomaly.
- It offers a viable alternative for managing bradyarrhythmias in individuals with PLSC and absent right SVC.
- Highlights the importance of recognizing and managing complex venous anomalies in device implantation.
Abstract:
Persistent left superior vena cava and absent right superior vena cava is an uncommon anatomical association. This is a challenging situation for permanent pacemaker implantation. We report three patients with this anomaly and a permanent pacemaker successfully implanted through the left superior vena cava and coronary sinus, without acute or chronic complications.
