What is a Bubble Study?
A Bubble Study is a technique used to obtain additional information from an echocardiogram. The technique uses saline (salt water) which is agitated by mixing it back-and-forth quickly between two syringes. This creates very small bubbles in the saline which, when injected into an IV in the arm, can be seen as they pass through the heart's chambers. These bubbles can be followed in your heart to determine if any bubbles do not follow the normal pathway of blood flow within your heart.
Why is a Bubble Study Needed?
Most commonly a bubble study is used to determine if a small hole is present in the wall (known as the atrial septum) between the two upper heart chambers. This information is important since these holes can be involved in causing strokes or blood pressure problems in the lungs.
What To Expect.
If the decision is made to include a Bubble Study in your echocardiogram and you agree to its' use, an IV will be started in your arm through which the agitated saline is injected. Echo pictures are then taken in the same manner as before the administration of the saline solution.
Is a Bubble Study Safe?
Side-effects and contraindications for Bubble Studies are rare. If you have questions or concerns about having a Bubble Study, please speak with your doctor.
