Figure 1 : Echocardiography on acute heart failure due to TC (A: diastole, B: systole), after treatment of heart failure (C: diastole, D: systole), and on reoccurrence of TC (E: diastole, F: systole)
Fig 1(A, B). Akinetic left ventricle wall motion is seen from the apical to mid portion (yellow arrows on Fig(B)), which does not match with the coronary arterial perfusion. Basal wall motion is hyperkinetic instead.
Fig 1(C, D). Thirty-five days after treatment of heart failure. Left ventricle wall motion improved to almost normal kinesis.
Fig 1(E, F). Sixty-three days after restarting osimertinib, akinetic left ventricle wall motion on apical portion was seen (yellow arrows on Fig(F)).
Figure 2: Electrocardiogram on baseline (A), on acute heart failure (B), after heart failure treatment (C, D), and on reoccurrence of TC (E).
Fig 2(A). Baseline electrocardiogram was normal sinus rhythm with heart rate of 71bpm.
Fig 2(B). On acute heart failure due to TC, an electrocardiogram showed complete right bundle branch block with heart rate of 92bpm.
Fig 2(C). Eleven days after treatment of heart failure. Negative T-wave with broad induction was observed.
Fig 2(D). Nine weeks after treatment of heart failure. ST changes has normalized.
Fig 2(E). Sixty-three days after restarting osimertinib. Negative T-wave with broad induction was observed.
