Overview
Overview
Cardiac CT scan may be helpful in the diagnosis of patent foramen ovale. Findings on CT scan suggestive of/diagnostic of patent foramen ovale include presence of a distinct “flap” in the left atrium at the expected location of the septum primum, presence of a continuous “column” of contrast material between the septum primum and septum secundum, connecting the left and right atria, and presence of a “jet” of contrast material from the column into the right atrium.

CT Scan
Patent foramen ovale may be diagnosed with ECG-gated cardiac CT angiography using 64-MDCT (multidetector computed tomography). Findings on cardiac CT scan suggestive of/diagnostic of patent foramen ovale include:[1]
- Presence of a distinct “flap” in the left atrium at the expected location of the septum primum.
- Presence of a continuous “column” of contrast material between the septum primum and septum secundum, connecting the left and right atria.
- Presence of a “jet” of contrast material from the column into the right atrium.
