Our study measured RV longitudinal strain (RVGLS) by CMR 2D tissue tracking and investigated its diagnostic role in patients with RV heart failure.

150 healthy volunteers in three age groups (G_{20-40 years}, G_41-60
years, and G_{61-80 years}) and 30 patients diagnosed as DCM were recruited.

Normal RVGLS was -23.9%±5.2% with significant higher values in females in G_41-60 and G_61-80. The cut-off value identified as -13.71% showed good sensitivity, specificity, positive and negative predictive value in diagnosing RV contractile dysfunction among DCM patients.

In summary, RVGLS were increased in females, and it benefited the evaluation of RV contractile function.
