Key result
Dor procedure successfully remodels posterior LV aneurysm and improves LVEF by ~11% in one patient.
Why the study?
Differentiation between true left ventricular aneurysm and pseudo-aneurysm remains difficult.
Case Report (n=1)
No
This case report highlights the diagnostic challenges in differentiating true left ventricular aneurysms from pseudo-aneurysms and demonstrates successful surgical management using the Dor procedure.
Emphasizes precise differentiation of post-MI aneurysms to select elective surgery; extends sparse case data on Dor procedure remodeling but requires prospective confirmation.
Rupture of the free wall of the left ventricle (LV) is a catastrophic complication occurring in 4% of patients after myocardial infarction (MI) and in 23% of those who die of MI.Rarely the rupture is contained by an adherent pericardium creating a pseudo-aneurysm.This clinical finding calls for emergency surgery.If no ruptures are detectable and myocardium wall integrity is confirmed, we are in the presence of a true aneurysm, which can be treated by means of elective surgery.Differentiation between these two pathologies remains difficult.We report the case of a patient with a true aneurysm, initially diagnosed as pseudo-aneurysm at our institution; we have reviewed the literature on this difficult diagnosis and outlined characteristic findings of each clinical entity.

Kim et al. (2026) conducted a case report in Left ventricular aneurysm (n=1). Surgical repair (Dor procedure) was evaluated on Post-surgical remodeling and ejection fraction.
