Association of regional myocardial conduction velocity with the distribution of hypoattenuation on contrast-enhanced perfusion computed tomography in patients with post-infarct ventricular tachycardia

Cardiac magnetic resonance imaging has been shown to be beneficial for identification of the ventricular tachycardia (VT) substrate prior to catheter ablation. Contrast-enhanced perfusion multidetector CT (CEP-MDCT) is more generalizable to clinical practice; and wall thickness and regional hypoenhancement on CEP-MDCT can identify potential substrate sites, albeit with decreased specificity.
