Implantation of a dual chamber pacemaker in a patient with persistent left superior vena cava.
A patient underwent dual chamber pacemaker implantation by puncture of the left subclavian vein. During the procedure we observed persistence of the left superior vena cava. A "J-shaped" atrial lead was used for ventricular pacing with excellent long-term results. This technique can be a valuable alternative when confronted with the problem of persistent left superior vena cava during pacemaker implantation.
