Catheter-Like Artifact After CABG Surgery
Artifacts are common during daily echocardiography practice and can lead to incorrect understanding of true anatomy. Misinterpretation of these artifacts can result in unnecessary or omitted procedures. Therefore, recognition of artifacts like the one in this case is very important because they could lead to unnecessary surgical intervention to remove a foreign body.
These images represent a 56-year-old man with history of three-vessel coronary artery disease who underwent coronary artery bypass graft surgery. In his post-operative echocardiogram, a large localized pericardial effusion at the posterior and lateral side of left ventricle was seen. Tube-like echo density was seen in pericardial space that was present in both the pericardial space on the left side of image in apical four-chamber view and inferior wall of right ventricle in subcostal view. There was no history of implantation of a catheter for drainage of pericardial or pleural fluid by the surgeon. Nothing abnormal was reported by gated non-contrast computed tomography scan. While we were probing for the reason of this finding, we observed two similar cases.
