Figure 3 CMR Image in Alcohol Ablation Patients

Short-axis plane cardiovascular magnetic resonance (CMR) image of the basal left ventricle (LV) from 3 hypertrophic cardiomyopathy patients showing pre-ablation morphology (left panels) and the area of the septal ablation created by infusion of alcohol on the post-gadolinium images (center, right panels). The images in the right panel are identical to those in the center panel and highlight the area of the infarct with broken lines. Post-ablation images (after gadolinium) show large areas of transmural hyperenhancement with irregular borders, indicative of necrotic tissue (white) in the region of the targeted ablation. Arrow shows an inhomogeneous area within the core of an infarct in which gadolinium uptake is absent because of severe microvascular obstruction (center patient). RV = right ventricle.
