Key result
Subepicardial LV aneurysms mimic false aneurysms in rupture risk, with incidence rising from post-MI thrombolysis.
Why the study?
Subepicardial aneurysms are distinct from true and false aneurysms but have a similar propensity for rupture, with increasing incidence due to thrombolytic therapy and more frequent discovery by early invasive diagnostics.
Case Report (n=17)
Subepicardial aneurysms are distinct from true and false aneurysms but carry a high risk of rupture, with increasing incidence linked to thrombolytic therapy.
Subepicardial LV aneurysms warrant rupture surveillance; Level 5 data leave open any thrombolysis link.
A case of subepicardial aneurysm is reported and 16 other cases found in the literature are reviewed. Although the subepicardial aneurysms are distinct from true and false aneurysms, their propensity for rupture is similar to false aneurysm. The incidence of this aneurysm is increasing due to the use of thrombolytic therapy in myocardial infarction. Early invasive diagnostic test is leading to its more frequent discovery.

Vossenberg et al. (1991) conducted a case report in Subepicardial aneurysm of the left ventricle (n=17). Subepicardial aneurysms of the left ventricle have a propensity for rupture similar to false aneurysms, and their incidence is increasing due to thrombolytic therapy in myocardial infarction.
