Figure 2. (A) Cardiac MRI: late gadolinium enhancement imaging
(PSIR) in short axis stack. There is patchy myocardial fibrosis in the
anterolateral papillary muscle and a small portion of the mid lateral
wall (thick arrows). There is a mid-wall fibrosis in the basal
anteroseptal segment (arrow head). Additionally, there is fibrosis at
both anterior and inferior right ventricular insertion sites (thin
arrows). The pattern of myocardial fibrosis is compatible with
non-ischemic cardiomyopathy. (B) Coronary angiography: (left) RAO
cranial of LCA, (middle) LAO caudal view of LCA, and (right) LAO view of
RCA. There was no significant coronary artery disease.
Video 1. Echocardiography of apical (A) 4-chamber, (B)
2-chamber, and (C) 3-chamber views. The left ventricle was mildly
dilated with severely decreased function. The right ventricular function
was moderately decreased. The left ventricular wall motion was globally
severely hypokinetic with regional variations. Inferior and inferoseptal
segments were akinetic, whereas the wall motion of basal anterior and
lateral segments were rather preserved. The findings were suggestive of
ischemic cardiomyopathy.
Video 2. Cardiac MRI steady-state free precession (SSFP) cine
imaging of long axis views: (A) 2-chamber, (B) 3-chamber, and (C)
4-chamber views. Cardiac MRI cine imaging showed severely dilated left
ventricle with severely decreased systolic function (ejection fraction
17%). The left ventricular wall is globally severely hypokinetic with
minimal regional variations. There were prominent trabeculations in the
anterior wall from base to apex, that did not meet the criteria for
non-compaction. The right ventricle was severely dilated with moderately
decreased systolic function.
