Marfan syndrome (MFS) is an inherent mutation of
encoding the fibrillin-1 protein. This protein is in
charge of forming microfibrils, which is a basic
material to build the elastic fibers. In this study, we
used dark-blood phase-contrast (PC) MRI to compute
myocardial wall motion velocity for MFS patients and
age-matched normal controls. MFS patients presented
higher systolic pVz values, shorter diastolic TTPz and
TTPr and achieved peak diastolic twist velocity in an
earlier phase. In conclusion, systolic pVz, diastolic
TTPz and TTPr, and twist velocity provide satisfied
information to diagnose myocardial function of MFS
patients.
