CTICasesVentricular Septal Rupture
Imaging findings
Cardiac CT obtained one week after a myocardial infarction demonstrates a large defect in the apical interventricular septum (ischemic VSD) with an associated rupture of the right ventricular free wall apex, resulting in contrast-opacified blood entering the adjacent pericardial/rupture space.
Key takeaways
Ventricular septal rupture (VSR) and free wall rupture are rare, catastrophic mechanical complications of acute myocardial infarction, typically occurring 3-7 days post-infarction during the phase of coagulation necrosis. VSR leads to a high-velocity left-to-right shunt and rapid clinical deterioration, requiring urgent surgical or percutaneous closure.
