Echo Bubble Study

Echo Bubble Study

Echo Bubble Study An echo bubble study can be performed during an echocardiogram. During the echocardiogram, a saline solution is rapidly mixed with air to produce tiny bubbles, and is then injected into the patient’s vein in their arm through an IV. The bubbles circulate up the vein into the right side of the heart, showing up on the echocardiogram. The bubbles should normally then be filtered out by the lungs. However, if these bubbles appear on the left side of the heart, this indicates that there is a hole (an ASD or PFO) between the heart’s two upper chambers (the left and right atria).
