Transient cerebral ischemia in an elderly patient with patent foramen ovale and atrial septal aneurysm

Figures & data

Table 1 Parameters to check on TEE

1. Atrial septum length and thickness

2. PFO tunnel length and amplitude

3. Presence/absence and measurement of septal aneurysm (basis excursion and amplitude)

4. Measurement of anterior–superior rim (minimum distance of the beginning of the tunnel from the atrial anterior–superior wall)

5. Presence/absence of atrial multifenestrated septum

6. Eustachian valve measurement

7. Presence/absence of Chiari network

8. Quantitative measurement of shunt by microbubbles (significant shunt for transition of >20 bubbles)

Abbreviations: TEE, transesophageal echocardiography; PFO, patent foramen ovale.
