Left ventricular pacing lead choice based on coronary sinus venous anatomy

Biventricular pacing is a new technique that is eliciting great interest in treatment of patients affected by cardiac heart failure. New leads have ma de it possible to stimulate the left ventricle via collateral branches of t he coronary sinus. However, anatomical variations of the coronary sinus cou ld make it very difficult to reach a good position in the coronary sinus an d gain a good pacing threshold. The release of new leads has partially solv ed this problem, but only a complete venogram of coronary sinus could guide the electrophysiologist towards the correct choice of lead.
