  • MRI imaging protocol for ARVD/C;
  • MRI structural abnormalities in ARVD/C;
  • MRI functional abnormalities in ARVD/C;
  • delayed enhancement of RV;

  • role of MRI in catheter ablation of VT in patients with ARVD/C


Accurate and reliable evaluation of the right ventricle (RV) is desirable both for establishing the diagnosis and for follow up evaluation of arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C). The non-invasive nature of magnetic resonance imaging (MRI), multiplanar capability, and unique ability to provide tissue characterization are ideal for assessment of RV structure and functional alterations in ARVD/C. Morphologic abnormalities on MRI include intramyocardial fat deposits, focal fibrosis, wall thinning, wall hypertrophy, trabecular disarray, and RV outflow tract enlargement. The introduction of quantitative MRI cut-offs for global RV volumes and function have refined the diagnosis of ARVD/C. Regional functional abnormalities of the RV described in ARVD/C include focal hypokinesis (wall thickening of <40%), akinesis (systolic wall thickening of <10%), dyskinesis (myocardial segment, which moves outward in systole) and aneurysms (segments with persistent bulging in diastole, and dyskinetic in systole). Serial quantitative volumetric assessment of RV may play an important in assessing RV function in first-degree relatives.
