Imaging findings
Chest CT demonstrates a highly disarranged, abnormal interventricular septum with multiple tunnel-like communications between the left and right ventricles. Contrast shunting is visible from the left ventricle into the right ventricular apex.
Key takeaways
Post-infarction ventricular septal defects (VSD) are serious complications of myocardial infarction. Even after surgical repair, patients may develop recurrent or residual shunts through complex, tunnel-like septal defects that can be evaluated with cardiac CT and addressed with percutaneous occluder devices.
