Atrial pacing via unilateral persistent left superior vena cava
Pacing and Clinical Electrophysiology : PACE
|July 1, 1986
Summary
A patient with sinus node dysfunction received a pacemaker despite having a rare left superior vena cava. The lead was successfully placed in the right atrium, demonstrating feasibility in challenging venous anatomy.
Area of Science:
- Cardiology
- Electrophysiology
- Anatomy
Background:
- Sinus node dysfunction and atrial tachycardias necessitate pacemaker implantation.
- Pacemaker lead placement typically utilizes the superior vena cava (SVC).
Observation:
- A patient presented with a unilateral left superior vena cava (LSVC) during pacemaker implantation.
- LSVC is a rare congenital anomaly with potential challenges for device implantation.
Findings:
- Despite the anatomical variation, a transvenous endocardial screw-in lead was successfully implanted.
- The lead achieved stable positioning in the lower lateral wall of the right atrium.
Implications:
- This case highlights the feasibility of transvenous lead implantation in patients with LSVC.
- Successful implantation in challenging venous anatomy expands options for patients requiring cardiac pacing.
