Revised Criteria for the Diagnosis of ARVD (Radiographics 2014; Rastegar N, et al. Cardiac MR findings and potential diagnostic pitfalls in patients evaluated for arrhythmogenic right ventricular cardiomyopathy. 34: 1553-1570):

Major Criteria:

Two-dimensional echo:
1- Regional RV akinesia, dyskinesia, or aneurysm; PLUS one of the following-

- Parasternal long axis RVOT ≥ 32 mm or parasternal short axis RVOT ≥ 36 mm
- Fractional area change ≤ 33%

MR imaging:
1- Regional RV akinesia, dyskinesia, or dyssynchrony; PLUS one of the following-

- Ratio of RV- end diastolic volume to body surface area ≥ 110 mL/m² (male) or ≥ 100 mL/m² (female)
- RVEF ≤ 40%

Minor Criteria:

Two-dimensional echo:
1- Regional RV akinesia, dyskinesia, or aneurysm; PLUS one of the following-

- Parasternal long axis RVOT ≥ 29 < 32 mm or parasternal short axis RVOT ≥ 32 < 36 mm
- Fractional area change of 33-40%

MR imaging::
1- Regional RV akinesia, dyskinesia, or dyssynchrony; PLUS one of the following-

- Ratio of RV- end diastolic volume to body surface area ≥ 100 to < 110 mL/m² (male) or ≥ 90 to < 100 mL/m² (female)
- RVEF > 40% to ≤ 45%
