Key result
A double interatrial septum associated with a left-sided atrial pouch was identified as the probable source of thrombus in a patient with cryptogenic stroke.
A double interatrial septum with a left-sided atrial pouch should be considered as a potential source of embolism in patients with cryptogenic stroke.
Highlights a rare anatomical variant to consider during imaging for cryptogenic stroke; leaves open the.
In this work, the case of a 70-year-old Caucasian woman affected by cryptogenic stroke is reported. After discarding other sources of embolism, a transesophageal echocardiogram was performed, which revealed the presence of a double interatrial septum associated with a left-sided atrial pouch. The persistent interatrial space was identified as the most probable source of thrombus.
