Computed tomography (CT) of the heart is a sophisticated imaging technique that utilizes multiple, narrow X-ray beams directed around a single rotational axis to capture a series of two-dimensional (2D) images of the heart and surrounding structures from various angles. This specific procedure, identified by CPT® Code 75573, is particularly focused on evaluating cardiac structure and morphology in patients with congenital heart disease. The process begins with the acquisition of non-contrast images, which may be necessary for initial assessment. Following this, a contrast material is injected through a previously established intravenous line, enhancing the visibility of the heart and major vessels in the subsequent images. The use of contrast material is crucial as it improves the differentiation of structures within the heart and vascular system, allowing for a more detailed evaluation. Once the images are obtained, a specialized computer software program processes the data to reconstruct three-dimensional (3D) images of the heart and great vessels. This advanced imaging capability enables the physician to produce thin, cross-sectional slices of the heart, facilitating a comprehensive assessment of both the left ventricular (LV) and right ventricular (RV) structures and functions. The evaluation may also extend to related vascular structures, providing a holistic view of the cardiovascular anatomy. After the imaging is completed, the physician reviews the findings and generates a dictated report that summarizes the results of the evaluation, which is essential for guiding further clinical management and treatment decisions in patients with congenital heart disease.

The procedure is indicated for the evaluation of congenital heart disease, specifically to assess the cardiac structure and morphology. The following conditions and symptoms may warrant the use of this imaging technique:
The procedure involves several key steps to ensure a comprehensive evaluation of the heart and vascular structures:
After the completion of the CT imaging procedure, patients may be monitored briefly to ensure there are no immediate adverse reactions to the contrast material. It is important for healthcare providers to provide patients with post-procedure instructions, which may include hydration recommendations to help flush the contrast material from the body. Patients should also be informed about any potential side effects of the contrast agent, such as allergic reactions or kidney function concerns, particularly in those with pre-existing renal conditions. Follow-up appointments may be scheduled to discuss the results of the imaging study and to determine any necessary further evaluations or treatments based on the findings.
