4D flow MRI andT1-Mapping: Assessment of altered cardiac hemodynamics and extracellular volume fraction in hypertrophic cardiomyopathy
2015
Journal of Magnetic Resonance Imaging
Purpose-Hypertrophic cardiomyopathy (HCM) is associated with altered hemodynamics in the left ventricular out flow tract (LVOT) and myocardial tissue abnormalities such as fibrosis. The aim of this study was to quantify changes in LVOT 3D hemodynamics and myocardial extracellular volume fraction (ECV, measure of fibrosis) and to investigate relationships between elevated flow metrics and left ventricular (LV) tissue abnormalities. Methods and Results-Cardiac MRI including 4D flow (field
