A cardiac myxoma (CM) is the most common benign primary tumor of the heart. It typically manifests as a
polypoid intracardiac mass, most often in the left atrium, attached to the interatrial septum. The attachment
point can be pedunculated, and a certain degree of mobility can occur depending upon the length of the stalk. The symptoms of the CM are usually unspecific or are similar to those of coronary artery disease (CAD). Surgical removal is considered the optimal treatment and must be carefully planned, especially when CM and CAD co-exist, and a combined operative strategy is contemplated. Therefore, it is important to evaluate the cardiac chambers as well as the coronary arteries prior to surgery. In this case, a cardiac CT is performed with prospective ECG triggering using one bolus of contrast injection. Multiple phases are reconstructed using acquired data to demonstrate the dynamic movement and the stalk of the mass. The best systolic and diastolic phases are automatically identified by the CT system. This significantly improves our daily workflow, with a great impact upon time-saving. The achieved image quality is optimal for a comprehensive evaluation, which enables the physicians to reach the diagnosis of CM, as well as to rule out CAD.
