MR Tissue phase mapping (TPM) allows the visualization of the distribution of myocardial velocities and their timing with complete LV coverage. Left bundle branch block (LBBB) and the associated asynchrony of LV function is associated with reduced prognosis in cardiomyopathy. Using TPM we could demonstrate a variety of differences in segmental myocardial performance in patients with dilated cardiomyopathy and LBBB compared to patients without LBBB.
