Early detection of left ventricular involvement in arrhythmogenic right ventricular cardiomyopathy by Feature Tracking

This retrospective study aimed to detect left ventricular myocardial strain by CMR-FT in ARVC patients. The 25 ARVC patients were divided into 2 subgroups: the preserved LVEF group (LVEF ≥50%, n=15) and the reduced LVEF group (LVEF <50%, n=10). The biventricular global and regional myocardial strain parameters in the radial, circumferential, and longitudinal directions were compared between ARVC and control group. ROC curve analysis showed the left ventricular basal longitudinal strain exhibited good performance in differential diagnosis between the LVEF ≥50% ARVC and the control group. In conclusion, CMR-FT can early detect left ventricular myocardial motion changes in ARVC patients.
