Left ventricular blood flow kinetic energy after myocardial infarction - insights from 4D flow cardiovascular magnetic resonance

Abstract

Reduction in LV systolic function results in reduction in systolic flow KEi_EDV. Infarct size is independently associated with the proportion of in-plane LV KE. Degree of LV impairment is associated with TD of peak E-wave KE. In patient with preserved EF post MI, LV blood flow KE mapping demonstrated significant changes in the in-plane KE, the minimal KEi_EDV and the TD. These three blood flow KE parameters may offer novel methods to identify and describe this patient population.
