Key result
Implantation of a cardiac resynchronization system using a novel research lead for left ventricular stimulation was successfully positioned in 23 minutes in a patient with a persistent left superior vena cava.
Why the study?
Can an experimental lead placed over a guidewire be successfully used for left ventricular stimulation in a patient with idiopathic dilated cardiomyopathy and a persistent left superior vena cava?
Case Report (n=1)
Can an experimental lead placed over a guidewire be successfully used for left ventricular stimulation in a patient with idiopathic dilated cardiomyopathy and a persistent left superior vena cava?
A novel experimental lead designed for over-the-wire placement can facilitate successful left ventricular lead positioning for cardiac resynchronization therapy in patients with complex venous anatomy such as persistent left superior vena cava.
Supports feasibility of novel over-the-wire LV lead in persistent left SVC; hypothesis-generating and requires prospective validation before broader use.
A persistent left superior vena cava (PLSVC) was discovered at the implantation of a cardiac resynchronization system in a woman with an idiopathic dilated cardiomyopathy. Standard leads were used to obtain right ventricular and right atrial (RA) stimulation according to a formerly described technique. The left ventricle was stimulated through the posterolateral vein of the heart by a novel lead design to be used over a guidewire for placement. Despite expected difficulties in this anatomic situation, the research lead was positioned in 23 minutes.

Lyon et al. (2000) conducted a case report in Idiopathic dilated cardiomyopathy with persistent left superior vena cava (n=1). Implantation of a cardiac resynchronization system using an experimental lead for left ventricular stimulation was evaluated on Positioning of the research lead. Implantation of a cardiac resynchronization system using a novel research lead for left ventricular stimulation was successfully positioned in 23 minutes in a patient with a persistent left superior vena cava.
