What is a common diagnostic tool used for all congenital heart defects?

The echocardiogram is the common diagnostic tool used for all congenital heart defects because it provides a non-invasive and detailed view of the heart's structure and function. This ultrasound-based technique allows healthcare providers to visualize the heart's chambers, valves, and blood flow dynamics in real-time. It is particularly useful in detecting abnormalities typical of congenital heart defects, including structural issues and functional impairments, without exposing the patient to radiation.

Given that congenital heart defects often involve complex anatomy and variations in blood flow, the echocardiogram's ability to provide both anatomical and functional information makes it the preferred diagnostic choice. This diagnostic tool can also be used for ongoing monitoring and assessment throughout a patient's life, making it indispensable in the management of congenital heart conditions. Other imaging modalities, while valuable in certain circumstances, do not match the specificity and utility of echocardiography in this context.
