Lead selection and implantation technique for biventricular pacing
Coronary venous leads are the leads of choice in cardiac resynchronisation therapy. They can be placed with excellent electrical thresholds in previously cardiotomised patients. Due to the enormous morphologic variability of the coronary venous anatomy, the leads have to be selected with respect to each individual case. The use of different leads make a coronary venous approach possible in 95% of all cases which is by far less traumatising than the epicardial one. The removal of even long-term implanted leads does not cause any difficulties. Epicardial leads should be placed, if the transvenous approach is technically unsuccessful or if cardiotomy is necessary for other reasons. In these cases biventricular stimulation can be performed by additional temporary pacing wires at the right atrium and both ventricles.Definitive right heart lead placement can be performed during a second procedure after recovery from the previous surgery.
