Effects of papillary muscles and trabeculae on left ventricular quantification: Increased impact of methodological variability in patients with left ventricular hypertrophy
Hypertrophy, Left Ventricular
Magnetic Resonance Imaging
Established cardiac magnetic resonance methods yield differences in left ventricular quantification due to variable exclusion of papillary muscles and trabeculae from myocardium. The relative impact of papillary muscles and trabeculae exclusion on calculated mass and ejection fraction is increased among patients with hypertrophy-associated left ventricular remodeling.
