Implication
Integration of MDCT/DE-MRI appears feasible for VT substrate mapping; leaves open whether it improves ablation outcomes.
Structured PICO
P
Population
9 patients undergoing VT ablation (3 ischemic cardiomyopathy, 3 nonischemic cardiomyopathy, 2 myocarditis, and 1 redo procedure for idiopathic VT)
I
Intervention
Integration of merged MDCT/MRI data in 3D-mapping systems for structure-function assessment and multimodal guidance of VT mapping and ablation
O
Outcome
Correlation of low-voltage areas (<1.5 mV) and local abnormal ventricular activities (LAVA) during sinus rhythm to delayed enhancement at MRI and wall-thinning at MDCTsurrogate
The integration of merged MDCT and DE-MRI data is feasible and accurately correlates structural substrate with electrophysiological abnormalities in scar-related VT.
