We evaluated cine DENSE MRI for the assessment of right
ventricular (RV) strain. Normal RV function was defined
by imaging subjects without heart disease. HF patients
demonstrated significant RV dysfunction as compared to
subjects without heart disease, and an association was
found between LV dyssynchrony and RV prestretch,
suggesting a previously unrecognized deleterious effect
on the RV due to LV dyssynchrony. Long-axis cine DENSE
MRI may provide new clinical insights regarding RV
dysfunction.
