Left bundle branch block-induced cardiomyopathy: Myth or reality?

Left bundle branch block (LBBB) is a frequent finding in heart failure population, especially in patients with dilated cardiomyopathy (DCM). Traditionally, LBBB was considered rather as a consequence than as a cause of the myocardial disease. This assumption was reinforced by the fact LBBB is associated with poor prognosis. However, the observation of “hyper-responders” to cardiac resynchronization therapy (CRT) among patients with DCM and LBBB, have contributed to the emergence of the entity of LBBB-induced DCM [1].
