Fig. 1. —Bar graph shows MRI detection rates of high signal intensity and delayed hyperenhancement in ablated septal wall after percutaneous transluminal septal myocardial ablation in patients with hypertrophic obstructive cardiomyopathy. Black bar represents detection rate for black blood T2-weighted fast spin-echo imaging, and white bar represents detection rate for contrast-enhanced inversion recovery fast gradient-echo imaging. Values at top of bars indicate number of patients whose images showed focal hyperintensity or delayed hyperenhancement of total number of patients who were examined with each technique. Both black blood T2-weighted fast spin-echo and contrast-enhanced inversion recovery fast gradient-echo imaging depicted ablated region clearly. A = Two of three patients who underwent MRI within 4 weeks of ablation showed central hypointense regions in ablated septal wall. B = In two patients, no focal high signals were identified in septal wall, but delayed hyperenhancement was visualized on contrast-enhanced MRI.
