GW28-e1114 The feasibility analysis of targeting the optimal coronary vein using the three-dimensional electroanatomic mapping during the LV lead implantation in CRT patients

Objectives The left ventricular lead (LV lead)location is one of the most important factors to improve cardiac resynchronization therapy(CRT)response, so it is critical to choose an optimal coronary vein during the implantation. The latest activation location was in the middle of lateral vein in 2 p...

Summary:Objectives The left ventricular lead (LV lead)location is one of the most important factors to improve cardiac resynchronization therapy(CRT)response, so it is critical to choose an optimal coronary vein during the implantation. The latest activation location was in the middle of lateral vein in 2 patients and 3 in the tip of posterolateral vein, LV lead successful implanted in these locations separately and the pacing parameter were appropriate, after the optimal biventricular pacing, QRS duration narrowed 39ms averagely.
