Overview
Echocardiography/Ultrasound
- When diagnosing patent foramen ovale, transesophageal echocardiography (TOE) is preferred over transthoracic echocardiography (TTE). It is the study of choice in patients suspected to have a paradoxical embolus.[1][2]
- The process of detecting a right-to-left shunt across a PFO involves the patient performing the valsalva maneuver while injected with a saline contrast medium. During the strain phase of the maneuver, the saline medium is injected into a peripheral vein and the atrial septum is visualized during the release phase of the maneuver.[2]
- Although tranesopheageal echocardiography is preferred, sedating the patient may lead difficulty in performing the valsalva maneuver.[2]
- Findings on an echocardiography suggestive of/diagnostic of a right-to-left shunt include:[2]
- Presence of bubbles across the inter-atrial septum into the left atrium.
