Deranged Myocyte Microstructure in Situs Inversus Totalis Demonstrated by Diffusion Tensor Cardiac Magnetic Resonance

To the Editor: In situs inversus totalis (SIT), there is mirror imaging of the situs solitus (SS) visceral arrangement; however, there are no histological studies examining the myocardial microstructure. Diffusion tensor cardiac magnetic resonance (DT-CMR) noninvasively interrogates the myocardial
