Patent Foramen Ovale (PFO) Work Up
A 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 Echo

A 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 Study
