Summary
Atrial septal aneurysm (ASA) cases showed no clinical events related to cardiogenic embolism over a five-year follow-up. This single-center study suggests ASA may not be a significant source of embolism in the absence of clinical events.
Area of Science:
- Cardiology
- Echocardiography
- Embolism
Background:
- Atrial septal aneurysm (ASA) is a cardiac anomaly.
- Previous studies suggest ASA may be a source of cardiogenic embolism.
- The clinical significance of ASA remains debated.
Purpose of the Study:
- To report clinical experience with atrial septal aneurysm.
- To evaluate the embolic potential of ASA in a single center.
Main Methods:
- Retrospective review of 7 cases of atrial septal aneurysm (ASA).
- Diagnosis confirmed by transthoracic echocardiography (TTE).
- Mean follow-up period of five years.
Main Results:
- Seven cases of ASA were identified between 1989-1996.
- No clinical events compatible with cardiogenic embolism were observed.
- Patients were followed for a mean of five years.
Conclusions:
- In this cohort, atrial septal aneurysm (ASA) did not appear to be a source of cardiogenic embolism.
- Further research is needed to clarify the embolic risk associated with ASA.
