Transvenous ventricular pacing options in Ebstein's anomaly.
Transvenous pacing in patients with Ebstein's anomaly is challenging due to anatomical abnormalities of the tricuspid valve and right heart chambers. This paper describes the various transvenous ventricular lead placement options for permanent pacing in patients with Ebstein's anomaly. In Ebstein's anomaly, stable long-term ventricular pacing can be achieved by positioning the lead either in the atrialised right ventricle, true right ventricle or the cardiac venous system. The pitfalls and advantages of pacing from these sites with the electrocardiographic and chest X-ray appearances are described.
