Figure 2 CMR Image in Surgical Myectomy Patients
Short-axis plane cardiovascular magnetic resonance (CMR) image of the basal left ventricle (LV) from 3 hypertrophic cardiomyopathy patients showing the area of septal myectomy before (left), 3 to 7 days after surgery (center), and also 3 to 7 days after myectomy after the administration of gadolinium (right). Arrows show the area and extent of the muscular septal resection. In the post-gadolinium images, normal myocardium appears dark and necrotic (infarcted) myocardium appears white. There is no evidence of intramyocardial delayed hyperenhancement at or near the myectomy site, indicating the absence of necrotic tissue. RV = right ventricle.
