OBJECTIVES: The purpose of our study was to assess the impact of revised versus original criteria on the prevalence of @entity4128 right @entity296 / @entity1141 (ARVC/D) criteria in cardiac magnetic resonance (CMR) studies. BACKGROUND: Recently, the ARVC/D task force criteria have been revised, aiming for a better diagnostic sensitivity. The implications of this revision on clinical decision making are unknown. METHODS: We retrospectively evaluated the CMR scans of 294 @entity1 referred for ARVC/D between 2005 and 2010, and determined the presence or absence of major and minor CMR criteria using the original and the revised task force criteria. Previously, major and @entity854 were identified by the presence of right @entity384 (global or segmental), right ventricle microaneurysm, or regional hypokinesis. The revised criteria require the combination of severe regional wall motion abnormalities (akinesis or dyskinesis or dyssynchrony) with global right @entity384 or dysfunction (quantitative assessment). RESULTS: Applying the original criteria, 69 @entity1 (23.5%) had major original criteria, versus 19 @entity1 (6.5%) with the revised criteria. Forty-three @entity1 (62.3%) with major original criteria did not meet any of the revised criteria. Using the original criteria, 172 @entity1 (58.5%) had at least 1 minor criterion versus 12 @entity1 (4%) with the revised task force criteria; 167 @entity1 (97%) with minor original criteria did not meet any of the revised criteria. In the subgroup of 134 @entity1 with complete diagnostic work-up of ARVC, 10 @entity1 met the diagnosis of proven ARVC/D without counting imaging criteria. Only 4 of 10 met major criteria according to the revised CMR criteria; none met minor criteria. However, 112 of 124 @entity1 without ARVC/D were correctly classified as negative by major and minor criteria (specificity 94% and 96%, respectively). CONCLUSIONS: In our experience, the revision of the ARVC/D task force imaging criteria significantly reduced the overall prevalence of major and minor criteria. The revision, although maintaining a high specificity, may not have improved the sensitivity for identifying @entity1 with ARVC/D. Larger studies including follow-up are required.
