Association of left ventricular flow energetics with remodeling after myocardial infarction: New hemodynamic insights for left ventricular remodeling

The upper panel summarizes the established and novel potential CMR-derived contributors to adverse LV-remodeling. The bottom panel represents the late-diastolic LV blood flow KE maps on 4-chamber and 2-chamber views, LV blood flow KE curves, and mitral inflow curves for each identified adverse LV-remodeling level (mild: 10–15%, moderate: 15–20%, severe: >20%). With no adverse LV-remodeling, the level of kinetic energetics during late-diastole (A-wave) appears high compared to during early-diastole (E-wave). As LV-remodeling emerges and advances, the level of kinetic energetics during late-diastole (A-wave) reduces and becomes lower compared to during early-diastole (E-wave). The reduction in LV blood flow energetics during late diastole (A-wave) is visually appreciated on KE maps. Concerning mitral inflow, a similar switch pattern is observed between early diastole and late diastole, as LV-remodeling emerges and advances.
