Impact of the recent revision of arvc task force criteria for cmr on criteria prevalence and diagnostic accuracy

Methods We retrospectively evaluated the CMR scans of 294 patients referred for ARVC between 2005 and 2010 and determined the presence or absence of major and minor CMR criteria using the original and the revised TFC. Previously, major and minor abnormalities were identified by the presence of RV dilatation (global or segmental), RV micro-aneurysm, or regional hypokinesis. The revised criteria require the combination of severe regional wall motion abnormalities (akinesis or dyskinesis or dyssynchrony) with global RV dilatation or dysfunction (quantitative assessment). For defining RV dilatation, we used the same quantitative cut-off values for both, original and revised criteria.
