Application of cardiac magnetic resonance strain analysis in arrhythmogenic right ventricular cardiomyopathy

CMR-FT can quantitatively evaluate myocardial motion. In this study, we find that the right ventricular global longitudinal, radial and circumferential strain in ARVC patients are significantly lower than those in normal controls. In ARVC patients with LVEF < 55%, the left ventricular global longitudinal, radial and circumferential strain decrease significantly. The left ventricular global longitudinal strain also decrease in ARVC patients with LVEF ≥ 55%. These results suggested that myocardial strain can be used to evaluate biventricular myocardial motion in ARVC patients.
