We experienced a very rare case of surgical management of a giant atrial septal aneurysm. It is an interesting case and is supported by preoperative, intraoperative, and pathology images.

Keywords: atrial septal aneurysm; atrial tachycardia; patent foramen ovale; thrombus.

FIGURE 1
FIGURE 1
Preoperative imaging of an arterial septal aneurysm. Multi‐slice computed tomography shows a giant ASA protruding into the right atrium and a thrombus attached to the left side of the ASA pouch (A). Transthoracic echocardiography shows an ASA attached to the right atrial free wall and protruding into the right atrium (B). ASA, atrial septal aneurysm; LA, left atrium; LV, left ventricle; RA, right atrium; RV, right ventricle
FIGURE 2
FIGURE 2
Intraoperative imaging findings. A giant atrial septal aneurysm protrudes into the right atrium (A). Patent foramen ovale (B). ASA, atrial septal aneurysm; RA, right atrium
FIGURE 3
FIGURE 3
Pathological findings of an atrial septal aneurysm. Blood‐stained gauze was placed inside the giant ASA to understand the nature of the thin tissue. A mixture of thickened and very thin tissues appeared vulnerable to imminent tears (A). Hematoxylin and eosin staining. (B, C) Histological section of very thin ASA tissues (B). Histological section of normal ASA tissues mixed with fatty cell infiltration (dotted arrow) and fibrosis (black arrow) (C). H&E staining, Hematoxylin and eosin staining, Magnification, ×100. ASA, atrial septal aneurysm
