Arrhythmias & electrophysiology
Cardiac magnetic resonance for ventricular arrhythmias: a systematic review and meta-analysis
Authors' conclusion
CMR is a valuable tool in the diagnostic and prognostic evaluation of patients with VAs.
Study context
- Population
- Adults undergoing cardiac magnetic resonance (CMR) for diagnostic or prognostic purposes in the setting of significant ventricular arrhythmias18 studies
- Comparison
- LGE present vs absent on CMR
- Outcome
- Prevalence of structural heart disease post-CMR evaluation
Methodological detailsrandom effects model
- Random effects model
Pooled result
As reported in the abstract
Prevalence of SHD post-CMR (all-comers with significant VAs)
Pooled rate of structural heart disease (SHD) post-CMR, all-comers
39%
SHD, PVCs and/or non-sustained VT subgroup
24%
SHD, more complex ventricular arrhythmias (VAs) subgroup
63%
