The test is an ultrasound scan which is designed to look for a hole in the heart called a patent foramen ovale (PFO). This is a small flap-like opening between the top two chambers of the heart which 1 in 4 people may have.

What does the test involve?

You will be asked to remove clothing from the top half of your body and a gown will be provided. You will then be asked to lie on a couch on your left side.

A mixture of salt solution (saline) with small bubbles will be injected into a vein in your arm to help show the heart more clearly. A small probe and gel will be placed on the front and side of your chest to allow staff to see your heart on a screen.

How long does it take?

The test time can vary from 45–90 minutes. However, most of this is preparation time and the scan only lasts around 20 minutes.

Medication

Please take your medication as usual on the day of the test.

When will I receive the results?

The recorded pictures will be reviewed and a report will be sent to the healthcare professional who requested the scan.

Driving after the test

There is no restriction on driving after this test.
