Integration of late-enhanced MRI and electroanatomical mapping for substrate ablation of poorly tolerated ventricular tachycardia.
We describe the case of a patient with a poorly tolerated ventricular tachycardia (VT) in which a substrate ablation was performed. The ablation was guided by the integrated images of the scar obtained by MRI and electro-anatomical mapping. This combined technique can make substrate ablation more accurate and may have a role in the ablation of unmappable VT.
