Arrthymogenic right ventricular dysplasia diagnostic criteria

For the diagnosis of arrthymogenic right ventricular dysplasia to be made patients must have either two major criteria, one major and two minor criteria, or four minor criteria.

Major criteria

  • global or regional dysfunction and structural alterations
    • severe dilatation of the right ventricle (RV) and reduced RV ejection fraction
    • severe segmental dilatation of the RV
    • localized RV aneurysm
  • tissue characterization
    • fibrofatty replacement of the RV myocardium (endocardial biopsy)
  • depolarization or conduction abnormalities
    • epsilon waves
    • prolongued QRS complex (>110msec) in V1-V3
  • family history
    • familial disease confirmed at autopsy or surgery

Minor criteria

  • global or regional dysfunction and structural alterations
    • mild dilatation of the right ventricle (RV) and reduced RV ejection fraction
    • mild segmental dilatation of the RV
    • regional RV hypokinesia
  • repolarization abnormalities
    • inverted T waves (V2-V3)
  • depolarization or conduction abnormalities
    • late potentials
  • arrhythmias
    • ventricular tachycardia with LBBB and frequent VES
  • family history
    • family history of sudden death due to suspected ARVD
    • family history of ARVD on diagnostic criteria
