This study examined the impact of CMR on clinical management in patients with undergoing evaluation for arrhythmogenic right ventricular dysplasia/cardiomyopathy(ARVD/C).
Patients referred for assessment of ARVD/C were evaluated. Using 2010 ARVD/C Task Force criteria, clinical history, family history, ECG and other test results were evaluated with and without CMR findings to determine definite, borderline or possible ARVD/C. CMR included assessment of right ventricular(RV) size, function, and regional wall motion(RWM). For alternative diagnoses, tissue characterization and late gadolinium enhancement were routinely performed. Qp:Qs was performed when intracardiac shunt was suspected by the supervising physician.
Clinical Impact of CMR on Diagnosis of ARVD/C vs. Alternative Diagnoses
2010 Guidelines without CMR Findings, n (%)
2010 Guidelines with CMR Findings, n (%)
Definite Criteria for ARVD/C
Borderline Criteria for ARVD/C
Possible Criteria for ARVD/C
Patients with 1 or no Minor Criteria, not meeting 2010 Guidelines Definition of \"Definite\", \"Borderline\" or \"Possible\"
RV Enlargement Alone**
CMR impacted clinical management by contributing to the diagnosis of definite or borderline ARVD/C in 4% of patients and by excluding the presence of significant RV dysfunction, enlargement, and RWM in over half of patients. CMR identified important alternative diagnoses in 16%.
