Transthoracic focused cardiac ultrasound imaging in the operating room is typically performed using phased array transducers.1,2  We present the portable ultrasound imaging of a 1.1-kg neonate in a short-axis parasternal view to demonstrate curvilinear transducer use for parasternal imaging, which provided clear structure resolution (left) and excessive artifact in near-field targets using a typical phased array transducer (right). The heart structure including the right (RV) and left ventricle (LV) is clear on the left (54 × 10 mm curvilinear transducer [2 to 9 MHz]), whereas the speckle artifact rendered the right image (26 × 20 mm phased array transducer [1 to 5 MHz]) uninterpretable.

Focused cardiac ultrasound imaging provides information for the management of critical situations in children and adults.1,2  In most operating rooms, a single...
