Figure 2: Gadolinium-enhanced cardiac magnetic resonance imaging. Two-chamber (a) and four-chamber (b) views obtained by magnetic resonance imaging after enhancement by gadolinium. In addition to left ventricular enlargement, the dark appearance of the left ventricular myocardium (arrows) indicated lack of delayed enhancement, suggesting that no fibrosis or other abnormalities in myocardial architecture were present. LV = left ventricle; RV = right ventricle; LA = left atrium; RA = right atrium.
