a Postoperative chest computed tomography in axial section. A postoperative enhanced chest computed tomography reveals hemorrhagic cardiac tamponade and extravascular leakage of contrast agent (red arrow) is shown in the pericardium. The staple line dividing the interlobar fissure is shown by the white arrow. b Postoperative chest computed tomography in coronal section. A postoperative enhanced chest computed tomography in coronal section reveals that the hemorrhagic tamponade and extravascular leakage of contrast agent (red arrow) is located at the apex of the heart. c Intraoperative image of coronary artery repair. A laceration is noted on the posterolateral branch of the left circumflex artery and blood was spurting out (white arrow)
