CTICasesPost-infarction ventricular septal defect
Imaging findings
Gated cardiac CT demonstrates a focal defect (rupture) measuring approximately one centimeter in the inferior aspect of the interventricular septum, in a patient with a recent myocardial infarction and right ventricular dilation.
Key takeaways
Ventricular septal rupture is a well-known, high-mortality mechanical complication of acute myocardial infarction, typically occurring 3 to 5 days post-infarction. Gated cardiac CT plays an important role in surgical or percutaneous closure planning.
