Abstract: -Right-to-left shunt (RLS) can be identified by contrast-enhanced transcranial Doppler (cTCD) in patent foramen ovale (PFO) patients. Aim: To evaluate cTCD for PFO screening comparing it to cTEE. Method: 45 previous cTCD performed for PFO diagnosis and correlated its findings with cTEE. Patients were submitted to a cTCD standardized technique and were divided in two groups according to RLS: Group 1, patients with a positive RLS and Group 2 when RLS was negative. Results: 29 (65%) patients were included in grou… Show more

“…The flap of the foramen ovale (septum primum) closes against the atrial septum (septum secundum) and normally fuses within the first two years of life. If the septum secundum covers the oval foramen, but does not seal to the septum primum, then a probable PFO exists that can be "opened" by the Valsalva or other maneuvers that increase right atrial pressure 1,2 . Prevalence of incomplete fusion is approximately 25-27% 1,3 and is associated with atrial septum aneurysm (ASA) in 50-80% patients in a global population 3 .…”
