English⧼Colon⧽ F2: Imaging findings of proband (III:4) as a 57-year-old woman. (A) Incomplete RBBB, non-specific ST-T change and regular sinus rhythm were seen on initial ECG. (B) Slight cardiomegaly (cardiothoracic ratio was 0.62) without pulmonary edema was detected on chest radiographs. (C) In the echocardiographic examination, the upper two panels showed increased thickness of the interventricular septum to a maximum of 20 mm (white arrows), consistent with HCMP. However, there was no systolic anterior motion of the mitral valve (lower panel). (D) Cine short axis view using a balanced steady-state free precession sequence revealed thickening of the apical septal and anterior wall of the left ventricle (white arrow in the first panel). Delayed enhancement images using the Turbo-FLASH sequence showed hyper-enhancement in the same area (white arrow in the second and third panel). RBBB: bundle branch block, ST-T: ST-T segment, ECG: electrocardiogram, HCMP: hypertrophic cardiomyopathy.
