Insights
A rare case of giant atrial septal aneurysm with thrombus, atrial septal defect, and left atrial appendage thrombus was found after stroke. This unusual combination of cardiac abnormalities has not been previously reported.
Area of Science:
- Cardiology
- Congenital Heart Disease
Background:
- Atrial septal aneurysm is a congenital heart abnormality.
- It can occur alone or with other cardiac issues.
- Over half of cases involve an atrial shunt.
Abstract:
Atrial septal aneurysm is a congenital abnormality that may occur as an isolated malformation or in combination with other cardiac abnormalities. More than half of the cases of atrial septal aneurysm are associated with an atrial shunt. We present a case with a thrombus at a giant atrial septal aneurysm associated with atrial septal defect and thrombus in the left atrial appendage, detected by transesophageal echocardiography after cerebral ischemic events. To the best of our knowledge, this combination has not been described in the literature so far.
