Abstract
Our experience with 121 coronary vein (CV) leads in 116 patients shows that CV leads are the leads of choice for pacing the left ventricle (LV). The information gained from pre-operative venous angiography permits individual selection of the most appropriate lead model for each case. The use of steerable electrophysiology catheters facilitates guide catheter cannulation of the coronary sinus (CS) when the anatomy is difficult and reduces the risk of complications. By selecting the CV lead model most suitable for each individual patient, we achieved successful implantation in 99.1% of patients. In this day and age, epicardial electrodes should be restricted to cases with CS anomalies which make CS cannulation impossible, and to LV lead implantation during heart surgery.
