Permanent right ventricular pacing through an anomalous left superior vena cava.
A persistent left superior vena cava can complicate the implantation of a transvenous pacemaker. In a patient who required a permanent pacemaker, this venous anomaly was discovered during the insertion of the electrode but it did not prevent long-term right ventricular pacing. This was achieved after the electrode had been manipulated through the coronary sinus and right atrium. A plan of management is proposed for dealing with this unexpected problem.
