A Pediatric 2D echo with Doppler is a non-invasive imaging test that uses sound waves to evaluate the structure and function of a child's heart. The test is similar to an adult echocardiogram, but it is specifically designed for infants and children. The 2D imaging evaluates the real-time structure and motion of the heart, while the Doppler measures the speed and direction of blood flow within the heart. Color flow Doppler mapping allows velocity information to be overlaid on a 2D image, providing data about intracardiac and abnormal blood flow characteristics. The information obtained from a pediatric 2D echo with Doppler is used to diagnose heart disease in children and guide management plans.
