Abstract:
PFO is diagnosed by echocardiography using the combination of transthoracic two-dimensional imaging of the interatrial septum, followed by color and spectral Doppler (and if necessary saline contrast) imaging. Transesophageal imaging is an important adjunct when transthoracic imaging is not conclusive or yields suboptimal images.Three-dimensional echocardiography is useful for defining fenestrations within a PFO.

Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...
