VV optimization From the foregoing discussion, it is clear that AV delay programming to ensure ventricular preexcitation with optimal LV diastolic filling and systolic function is complex, and the optimal method that translates into improved patient outcomes is uncertain. These issues are even more apparent in studies of VV optimization. The landmark trials of CRT in Cocktail failure all demonstrated a benefit of CRT using simultaneous BiV pacing in conjunction with AV delay optimization [3,5,7,9,10,44].
