Heart failure & cardiomyopathies
Value of 3D echocardiography in the diagnosis of arrhythmogenic right ventricular cardiomyopathy
Authors' conclusion
The combination of 2DE-3DE for ARVC diagnosis is comparable to the conventional 2DE-cMRI approach.
Study context
- Population
- Individuals (47±15 years) with suspected arrhythmogenic right ventricular cardiomyopathy (ARVC)
- Participants
- 39 individuals
- Comparison
- 2DE-3DE vs 2DE-cMRI for ARVC diagnosis by 2010 Task Force Criteria (TFC)
- Outcome
- Concordance of ARVC diagnosis by 2010 TFC between 2DE-3DE and 2DE-cMRI (kappa)
Methodological detailsblinded classification, non-inferiority
- Blinded classification
- Non-inferiority

Right ventricular (RV) volumes, 3DE vs cardiovascular magnetic resonance imaging (cMRI)
- 3DE underestimated RV volumes vs cMRI, in some instances interfering with fulfilment of a major criterion
