Key result
Coronary sinus balloon venoplasty successfully enabled the distal positioning of a left ventricular lead in a small-diameter branch vein with acceptable electrical parameters.
Why the study?
Does balloon venoplasty enable successful left ventricular lead implantation in patients with a small diameter posterior-lateral branch during cardiac resynchronization therapy?

Does balloon venoplasty enable successful left ventricular lead implantation in patients with a small diameter posterior-lateral branch during cardiac resynchronization therapy?
Balloon venoplasty can be a useful technique to overcome challenging coronary sinus anatomy, specifically a small diameter posterior-lateral branch, during LV lead placement for CRT.
May facilitate LV lead placement in small CS branches during CRT; hypothesis-generating case report requiring prospective validation.
As the use of cardiac resynchronization therapy for mild to severe heart failure has increased over the last few years, the implanting electrophysiologist has been driven to learn innovative techniques addressing the technically challenging aspects of device implantation.Specifically, positioning the left ventricular (LV) lead via the coronary sinus (CS) can be challenging because of unsuitable CS anatomy, vein stenosis, and unacceptable electrical parameters.This report describes successful LV lead implantation by using balloon venoplasty to overcome a small diameter posterior-lateral branch.
