What is an interatrial septal aneurysm?
Interatrial septal aneurysm or atrial septal aneurysm (ASA) is defined as an abnormal protrusion of the interatrial septum. The exact length of the protrusion that defines an interatrial septal aneurysm varies in the literature, ranging from >11 mm to >15 mm beyond normal excursion in adults 4,5 and 5 mm in children.
Is atrial septal aneurysm normal?
Atrial septal aneurysm is rare (ASA) and is most often an accidental finding. However it could be a contributing factor to cardioembolic stroke even though no thrombus in aneurysm or left atrium can be seen in transthoracic echo. Patient was started on anticoagulants and rate control for atrial fibrillation.
Can you fix inter atrial septal aneurysm?
If ASD does not close on its own, heart surgery is required to close the defect. In some cases, ASD may be closed interventionally through a closure device.
What is the treatment for interatrial septal aneurysm?
Atrial septal aneurysms (ASAs) are uncommon but are associated with significant embolic morbidity when an interatrial communication is present. Although surgical reconstruction has traditionally been approached through a median sternotomy, minimally invasive techniques may be employed to reduce pain and recovery time.
What causes interatrial septal aneurysm?
An aneurysm of the interatrial septum is an infrequent finding in adult patients. Atrial septal aneurysm is a congenital malformation of the septum primum layer of the interatrial septum but differences between interatrial pressure forces have also been reported as a cause of its development.
How common is interatrial septal aneurysm?
[1] The widespread availability of transthoracic and transoesophageal echocardiography has identified atrial septum aneurysm with increasing frequency. [5] The frequency of the anomaly in the general adult population is low (2.2%). [1] It has been speculated that ASA is a direct source of thrombus formation.
What is the treatment for an atrial septal aneurysm?
Atrial Septal Aneurysm Symptoms. Symptoms of an atrial septal aneurysm are similar to those seen in other congenital heart defects,such as shortness of breath or fatigue.
How bad is an atrial septal aneurysm in the heart?
Symptoms of an atrial septal aneurysm are similar to those seen in other congenital heart defects, such as shortness of breath or fatigue. An atrial septal aneurysm increases the risk of stroke or a transient ischemic attack ( TIA ), a so-called “mini” or “warning” stroke.
When is an atrial septal aneurysm identified incidentally?
Most often, atrial septal aneurysms are discovered during a clinical examination for an accompanying heart issue. An atrial septal aneurysm is a deformity that causes a protrusion of the septum, the thin tissue separating the upper chambers of the heart, notes the Annals of Pediatric Cardiology medical journal.
What does “interatrial septum is aneurysmal”?
The interatrial septum is the thin wall that separates the upper atrial cavities of heart. When it appears elongated and “floppy” on cardiac ultrasound, we call it “aneurysmal”. This is a condition that some people are born with. It alone portends no prognostic risk.
