Electrocardiogram showing sinus rhythm, an incomplete right bundle branch block and an ST-segment elevation in leads V1 through V5 with biphasic T waves in V4-V6. No reciprocal ST segment depression or Q waves abnormalities were seen

T wave inversion and an incomplete right bundle branch block [Figure 1] similar to the ECGs recorded during his hospital admission at the age of eleven previously. The ECG at the time of coarctation surgery was reported as showing right bundle branch block and right atrial enlargement only.
Magnetic resonance imaging examinations to assess myocardial inflammation. (a) Transverse T2-weighted triple-inversion-recovery magnetic resonance image showing a normal edema ratio. (b) Postcontrast transverse T1-weighted fast spin-echo magnetic resonance image showing a normal global relative enhancement. (c) Mid-ventricular short-axis with late gadolinium enhancement showing thinning of the anteroseptal segment of the left ventricle (arrowhead) and normal delayed enhancement in the left ventricular walls. In B an additional saturation section is positioned across the atria to reduce signal from slow-flowing blood. ER and gRE are calculated according to the method of Friedrich et al.

T2-weighted triple-inversion-recovery imaging was used to calculate the myocardial edema ratio (ER), a normal T1-weighted imaging before and after contrast agent administration was used to determine the myocardial global relative enhancement (gRE), and a normal inversion-recovery gradient-echo imaging was used to evaluate areas of late enhancement (LE) [Figure 2].
