Summary
Aneurysms of the atrial septum (AAS) pose a risk for cerebral emboli, particularly when combined with cardiac anomalies. Further research is needed to determine optimal anticoagulation strategies for these patients.
Area of Science:
- Cardiology
- Neurology
- Vascular Medicine
Context:
- Aneurysms of the atrial septum (AAS) are rare cardiac anomalies.
- AAS are often associated with other cardiac conditions, such as patent foramen ovale.
- The embolic potential of AAS has been a subject of investigation.
Purpose:
- To investigate the association between AAS and ischemic stroke.
- To evaluate vascular risk factors and cardiac causes of embolism in patients with AAS.
- To assess the outcomes of anticoagulation therapy in this patient cohort.
Summary:
- A study of six patients with ischemic stroke and AAS revealed that four cases were considered cardio-embolic in origin.
- Echocardiography identified AAS in all patients; no atrial thrombi were found.
- Three patients had carotid artery disease, and three had vascular risk factors.
- No patient experienced further cerebral ischemic events after treatment, suggesting a potential benefit of anticoagulation.
Impact:
- This study highlights the potential risk of cerebral embolism associated with AAS.
- It suggests that combined cardiac anomalies and arrhythmias may synergistically increase embolic risk.
- The findings underscore the need for further research into the optimal management, including anticoagulation, for AAS patients.
