Magnetic resonance imaging findings in suspected arrhythmogenic right ventricular dysplasia.
BACKGROUND
Cardiac magnetic resonance imaging (CMRI) has been used to evaluate right ventricular morphology in suspected arrhythmogenic right ventricular cardiomyopathy (ARVC). We report qualitative CMRI findings in patients with suspected ARVD.


METHODS
A retrospective review of images in 35 patients referred for CMRI with clinically suspected ARVD.


RESULTS
Eleven patients were considered to have alterations on CMRI. In 5 patients a dilated outflow tract and/or right ventricle was identified; a high intramyocardial T1 fat signal was identified in one patient, regional dyskinesia in two patients, and small excavated pouches in 4 patients. Prominent right ventricular trabeculae were present in 4 patients.


CONCLUSIONS
CMRI alterations used for diagnosis of ARVC were identified in approximately one-third of patients referred to our center with either clinical suspicion or diagnosis of ARVC.
