New‐onset left bundle branch block‐associated idiopathic nonischemic cardiomyopathy and time from diagnosis to cardiac resynchronization therapy: The NEOLITH II study

Does earlier CRT implantation improve cardiac remodeling in patients with new-onset LBBB-associated idiopathic NICM compared to delayed CRT?

Earlier CRT implantation in LBBB-associated idiopathic NICM is associated with more favorable cardiac remodeling, suggesting a critical window to halt progressive myocardial damage.
