How accurate is a bubble echocardiogram?

A bubble echocardiogram is a highly sensitive and reliable test for detecting even the smallest openings between the heart’s chambers. When performed by an experienced cardiac physiologist, it can identify abnormal blood flow that may not be visible on a standard echocardiogram. If results are unclear or if further detail is needed, your consultant may recommend an additional imaging test such as a transoesophageal echocardiogram (TOE) or cardiac MRI for confirmation.
