Arrhythmogenic Cardiomyopathy

Home Clinical examples Cardiomyopathy Arrythmogenic cardiomyopathy

5 key points

  • The hotspot region in ARVC is the subtricuspid region (basal segment). This is the most and earliest affected RV region.
  • Regional deformation characteristics are: 1) reduction of peak systolic strain below -18%, 2) a prolonged time to onset shortening >100 ms, and/or 3) post-systolic shortening >15%.
  • RV mechanical dispersion ≥37 ms (SD of regional timing peak shortening) is associated to ventricular arrhythmias.
  • Left ventricular involvement is most often seen in the posterolateral region.
  • Normal deformation imaging findings does not completely rule out this disease. However, deformation abnormalities might precede conventional abnormalities

Cases

  • Arrythmogenic cardiomyopathy: Left ventricular involvement
  • Arrythmogenic cardiomyopathy: Severe right ventricular disease
  • Arrhythmogenic Cardiomyopathy - Preclinical Stage
  • Dilated cardiomyopathy with features of ARVC
