Does MDCT-derived regional myocardial wall thinning correlate with arrhythmogenic substrate in postinfarction ventricular tachycardia?
Effect estimate: R=0.82
p-value: p=0.001
MDCT-derived regional myocardial wall thinning correlates with low-voltage regions and LAVA, offering a viable substrate imaging alternative for postinfarction VT patients with MRI-incompatible devices.
Komatsu et al. (2013) conducted an observational in Postinfarction ventricular tachycardia (n=13). Regional myocardial wall thinning (WT) imaged by MDCT was evaluated on Correlation between areas of WT <5 mm and endocardial low voltage (R=0.82, p=0.001). Regional myocardial wall thinning <5 mm on MDCT significantly correlated with endocardial low-voltage areas (R=0.82; P=0.001) in patients with postinfarction ventricular tachycardia.
