Key result
Shared imaging characteristics complicate the differentiation of true LV aneurysms and pseudoaneurysms post-MI.
Why the study?
Despite advanced imaging techniques, differentiating between true left ventricular aneurysms and pseudoaneurysms after myocardial infarction remains challenging and not always binary.
Design
Review
Requires caution differentiating post-MI LV aneurysms on imaging; leaves open need for refined diagnostic criteria.
Left ventricular (LV) aneurysms and pseudoaneurysms are two complications of myocardial infarction (MI) that can lead to death or significant morbidity. Despite the availability of advanced imaging techniques, the differential between true aneurysms and pseudoaneurysms is not always binary. Thinned myocardium, small myocardial discontinuities and the differentiation between intramural and cavity thrombus can pose particular difficulties particularly in the setting of transmural infarction.

Scully et al. (2024) studied this question. True aneurysms and pseudoaneurysms of the left ventricle after myocardial infarction can be difficult to differentiate due to similar imaging characteristics.
