But on the papillary muscles of the left ventricle there were two circumscribed, round, echogenic mass measuring 18.2 mm by 8.3mm and 13.5mm by 8.3 mm (Figure 1).

Upon evaluation of the outflow tract, both the LVOT (left ventricular outflow tract) and RVOT (right ventricular outflow tract) have normal anatomy and function using 2D and CF ultrasound evaluation (Figure 2).

An echocardiography study by a pediatric cardiologist revealed well-circumscribed hyperechoic masses on both left ventricular papillary muscles, each measuring 21.8 mm by 9.2 mm and 14.7 mm by 8.5 mm (Figure 3) and creating no left ventricular inflow obstruction (Supplementary Video 1).
