This study is looking for volunteers aged 18 and older who are already scheduled to have a transesophageal echocardiogram (TEE) with a bubble study to check for a Patent Foramen Ovale (PFO). A PFO is a small opening between the upper chambers of the heart. The study is testing a new, battery-powered, non-invasive ultrasound device called "Point-of-care ultrasound." This device aims to detect microbubbles in the brain's blood vessels, which can indicate a right-to-left shunt (blood flowing from the right side of the heart to the left). The main goal is to see how well this new device can detect these shunts during your TEE procedure. The study plans to enroll 75 participants, but its current recruitment status is unclear.

Study design

This is an observational study, meaning researchers will observe and collect data without giving new treatments. It plans to include 75 participants.

What's involved

You would undergo a Point-of-care ultrasound diagnostic test during your scheduled TEE procedure.

Compensation

Not stated in the trial record.

Follow-up

The primary outcome is measured during the TEE procedure, so there is no specified follow-up period after that.
