Left juxtaposed atrial appendages: diagnostic two-dimensional echocardiographic features
Journal of the American College of Cardiology
|May 1, 1983
Summary
Left juxtaposition of the atrial appendages, a rare heart anomaly, can now be diagnosed noninvasively using two-dimensional echocardiography. This improves pre-surgical planning for congenital heart disease interventions.
Area of Science:
- Cardiology
- Medical Imaging
- Pediatric Cardiology
Background:
- Left juxtaposition of the atrial appendages is a rare congenital anomaly often linked to cyanotic heart disease.
- Accurate diagnosis is crucial for planning interventions involving the atrial septum, such as septostomy or Fontan anastomosis.
- Diagnosis is frequently incidental during surgery or autopsy, highlighting the need for noninvasive methods.
Purpose of the Study:
- To describe the two-dimensional echocardiographic features of left juxtaposed atrial appendages.
- To establish echocardiography as a noninvasive diagnostic tool for this anomaly.
Main Methods:
- Two-dimensional echocardiography was utilized to visualize the cardiac structures.
- Specific attention was paid to the atrial septum and the position of the right atrial appendage.
Main Results:
- Characteristic echocardiographic alterations in the atrial septum plane were identified.
- Malposition of the right atrial appendage was visualized, aiding diagnosis.
- These findings enabled noninvasive diagnosis of left juxtaposed atrial appendages.
Conclusions:
- Two-dimensional echocardiography provides a reliable method for noninvasive diagnosis of left juxtaposed atrial appendages.
- Early diagnosis through echocardiography can significantly impact the management of patients with congenital heart disease.
- This technique offers a valuable alternative to intraoperative or post-mortem diagnosis.
