case_images: And there was no evidence of coronary artery stenosis (Figure 1).
case_images: Two-dimensional echocardiogram showing an echogenic mass measuring 53 x 30 mm2, arising from the interatrial septum and anterior leaflet of mitral valve.

case_images: fig2-2050313X17736230
case_images: Two-dimensional echocardiography was followed, and a large gelatinous mass measuring 53 x 30 mm in the left atrium was founded (Figure 2).
case_images: Horizontal (a) long-axis MIP and (b) short-axis MIP images of cCTA revealed an atrial branch from the left circumflex artery (yellow arrow head) supplying a large left atrial mass originating from the interatrial septum and anterior leaflet of mitral valve.. MIP: maximum intensity projection; cCTA: cardiac computed tomography angiography.

case_images: The mass was mainly fed by sinus node branch of left circumflex artery (Figure 3(a) and (b)).
case_images: Gross findings of the myxoma.

case_images: The patient underwent open-heart surgery to remove the left atrial myxoma (Figure 4).
case_images: Histologic examination showed spindle-shaped cells and stellate cells in a myxoid stroma (H&E stain, x100).
