Transcranial Doppler for patent foramen ovale screening: is there a good correlation with transesophageal echocardiography?

Transcranial Doppler for patent foramen ovale screening: is there a good correlation with transesophageal echocardiography?

UNLABELLED 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...

A comparison of transesophageal echocardiography and transcranial Doppler sonography with contrast medium for detection of patent foramen ovale.

BACKGROUND Patent foramen ovale as a possible stroke risk factor can be diagnosed with transcranial Doppler sonography (TCD) by detecting intravenous contrast medium crossing from the right to the left atrium. The present study evaluates the reliability of this method. SUMMARY OF REPORT We performed TCD and transesophageal echocardiography simultaneously in 50 patients using galactose microbu...

PFO or UFO: how good is transesophageal echocardiography in identifying patent foramen ovale as the cause of a cryptogenic stroke?

Is patent foramen ovale a family trait? A transcranial Doppler sonographic study.

BACKGROUND AND PURPOSE Patent foramen ovale (PFO) is a frequent finding in young patients with stroke. The aim of this study was to assess whether PFO is a family trait. METHODS Sixty-two consecutive patients younger than 60 years of age with ischemic stroke and 62 age and gender-matched control siblings were examined by means of contrast transcranial Doppler (TCD) of the middle cerebral arte...

Transesophageal echocardiography for quantifying size of patent foramen ovale in patients with cryptogenic cerebrovascular events.

BACKGROUND AND PURPOSE Patent foramen ovale (PFO) is a risk factor for paradoxical embolism, and severe shunting and wide opening of PFO are risk factors for severe and recurrent cerebrovascular events. Neither contrast echocardiography nor 2-dimensional (2D) measurement of PFO size have been validated or compared with invasive balloon sizing. METHODS We performed transesophageal echocardiogr...
