Patent Foramen Ovale (PFO) Work UpA patent foramen ovale is a flap-like portion of the atrial septum, which separates the left and right chambers of the heart. The PFO usually closes at birth but can remain unsealed in approximately 25% of the population. In most cases, a PFO is a normal finding however it can be a relevant finding in young patients with unexplained stroke or transient ischaemic attacks (TIAs).
To accurately assess for the presence of a PFO, the following are performed:
Comprehensive EchoView Transthoracic Echo
Agitated Saline Contrast StudyA cannula is placed in your arm and a small amount of saline solution (salty water) is injected while asking you to perform different breathing exercises whilst some imaging is performed.
+/- Transcranial Doppler StudyThis involves using a small ultrasound transducer on the side of your head and imaging is performed during the saline injections.
Test DurationApproximately 90 minutes.
