Co-localization of areas of delayed mechanical activation and areas of myocardial scar

Year: 2009

Type: article

Abstract: The greatest benefit from Cardiac Resynchronization Therapy (CRT) is likely achieved when the LV pacing lead is placed in the area with the greatest mechanical activation delay[ 1 ]. However, in patients with ischemic heart failure, the region with the greatest mechanical activation delay may correspond to an area of myocardial scar. Placing the pacing leads in areas of scar tissue will result in nonresponse to CRT[ 2 ]. The co-localization of areas of delayed mechanical activation and myocardial scar in patients with previous MI is not known.
