Why Do I Need a Bubble Echocardiogram?

What is the purpose of a bubble study?

A bubble study gives added information, as it can identify potential blood flow issues inside your heart. For the bubble study, you will get an intravenous (IV) line in a vein in your arm. A saltwater solution called saline is mixed with a small amount of air to create tiny bubbles and then injected into your vein.

What is a bubble contrast echocardiogram and why is it used?
