An unusual interatrial septum

Echocardiography. 2020 Jan;37(1):150-151. doi: 10.1111/echo.14576. Epub 2020 Jan 6.


The images focus on a very rare atrial septal anatomy known as "double atrial septum with persistent interatrial space." Only scarce reports of this anomaly are found in literature. Due to increasing use of catheter-based interventions requiring a transseptal puncture, the recognition of this anomaly is essential for performing safe and effective procedures.

Keywords: double interatrial septum; interatrial space; septal fusion; septal pouch.
