Do scar characteristics on contrast-enhanced MRI predict sustained ventricular tachycardia in patients with advanced heart failure?
The presence and magnitude of nontransmural scar tissue on contrast-enhanced MRI may predict sustained ventricular tachycardia in patients with advanced heart failure.
Yokokawa et al. (2009) conducted an observational in Advanced heart failure (dilated and ischemic cardiomyopathy) (n=47). Contrast-enhanced magnetic resonance imaging (CMR) scar assessment vs. Patients without sustained ventricular tachycardia was evaluated on Occurrence of sustained ventricular tachycardia (VT). The presence and greater magnitude of nontransmural scar tissue on contrast-enhanced MRI predicted sustained ventricular tachycardia in patients with advanced heart failure.
