Permanent pacemaker positioning via the inferior vena cava in a case of single ventricle with loss of right atrial-vena cava continuity.

Successful dual chamber pacing was achieved by implanting permanent pacemaker leads using an extra-peritoneal approach to the inferior vena cava in a 48-year-old patient with a single ventricle, transposition of the great vessels, and a right atrial pulmonary artery shunt (Glenn's procedure). The pacemaker generator was implanted into a subcutaneous pocket in the anterior abdominal wall.
