【 摘 要 】

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 group 1 and 16 (35%) in group 2. PFO confirmation by cTEE was performed in 28 (62%) patients. cTCD had a 92.85% sensitivity, 82.35% specificity, 89.65% positive predictive value and 87.5% negative predictive value when compared to cTEE for PFO diagnosis. CONCLUSION: Standardized technique cTCD allows for RLS visualization in PFO patients with a good correlation with cTEE and can be used as a screening test before cTEE.
