The impact of new proposed arrhythmogenic right ventricular cardiomyopathy (ARVC) criteria on CMR diagnosis

Methods From January 2001 to December 2010, we studied 457 pts (279 males, 178 females; mean age 47±18 yrs) to exclude/confirm a clinical suspicion of ARVC; this suspicion was based on combination of clinical signs and symptoms, 12 leads-ECG data, anamnestic data, electrophysiologic data, and pathologic data, when available. All CMR were performed with a clinical 1.5 T scanner (Signa Excite 2, GE Medical Systems), using a standardized protocol for cardiomyopathies (triple IR-black blood sequence, cine-SSFP on three axis optimized for RV, and late enhancement with 2D IR-FGRE).
