Non-contrast magnetic resonance imaging for guiding left ventricular lead position in cardiac resynchronization therapy

摘要

Purpose A left ventricular lead position concordant to viable myocardium at the site of latest mechanical activation is associated with a better response to cardiac resynchronization therapy (CRT). The present study aimed to guide left ventricular (LV) lead implantation into a vein over the area of latest mechanical activation with no transmural scar as determined by radial strain measured by non-contrast magnetic resonance imaging (MRI).
