case_images: An echocardiogram in the ED demonstrated a left atrial mass with a broad base attachment to the atrial septum (Figure 1) that extended from the opening of the pulmonary veins to the mitral annulus. T2-weighted images and showed restricted diffusion (Supplementary Figure S1). There was heterogeneous enhancement on both early and late postcontrast images. The findings were compatible with a cardiac myxoma (Supplementary Video S1).
case_images: (A) CTA revealing a 41 mm x 27 mm x 33 mm broad-based lobulated mass in the left atrium that extends into the mitral annulus. (B) CTA reconstruction to show the mass extending to the right upper pulmonary vein (RUPV).

case_images: Subsequent investigation with coronary computed tomography angiography (CCTA) revealed a 41 mm x 27 mm x 33 mm broad-based lobulated mass in the left atrium that extended onto the mitral annulus (Figure 2). The tumor had a gelatinous quality, consistent with that of a myxoma, and was sent to pathology for confirmation (Supplementary Figure S2).
case_images: 3D-printed models of the myxoma.

case_images: A CCTA with a three-dimensional (3D) reconstruction of the mass, including a 3D-printed model of the patient's heart depicting the mass and relationship with adjacent structures, was obtained to help with surgical planning (Figure 3). The final pathology report confirmed a cardiac myxoma with no malignancy (Supplementary Figure S3).
