case_images: Left ventricular (LV) calcification detected by echocardiography and computed tomography angiography (CTA). At 2.5 months of age, (A) echocardiography showing increased echo of LV endocardium and (B) CTA showing diffusely distributed calcification of the LV endocardium. At 4 months of age, (C) echocardiography showing diffusely distributed calcification of the LV endocardium, chordae tendineae, and papillary muscle.

case_images: The echocardiogram (Table 1) showed moderate-to-severe stenosis of the main pulmonary artery and its branches (Vmax = 3.3-4.2 m/s), a gradient of 55 mmHg across the upper aortic valve, mild aortic arch stenosis with a gradient of 36 mmHg in the setting of LV dysfunction (EF = 35%, E/e' Lat = 16.2), and increased echo of LV endocardium (Figure 1A). Computed tomography angiography showed aortic stenosis, pulmonary artery stenosis, and diffusely distributed calcification of the LV endocardium (Figure 1B). Echocardiography at the age of 4 months showed improved LV systolic function (EF = 42%, E/e' Lat = 15.9) with diffusely distributed calcification of the LV endocardium, chordae tendineae, and papillary muscle (Figure 1C).
case_images: Electrocardiogram at 2.5 months of age showing T-wave flattening or inversion in leads I, aVL, and V5, and left ventricular hypertrophy was suspected.

case_images: The electrocardiogram (Figure 2) showed ST-T changes, and LV hypertrophy was suspected.
