TCD and PFO Study Results

TCD is Superior to TEE for Detection of PFO (Patent Foramen Ovale)

AHAScience News-International Stroke Conference 2014-San Diego

Ralph Sacco, MD, FAHA, past-president of the American Heart Association, interviews David Spence, MD, primary investigator of the trial, “Transcranial Doppler Is Superior to Transesophageal Echocardiography in Detection of Patent Foramen Ovale,” which he presented at ISC 2014 in San Diego.

TCD and PFO Study Summary:

The researchers conducted a study to compare the performance of transcranial Doppler (TCD) with transesophageal echocardiography (TEE), the standard method for diagnosing a right-left shunt such as PFO. They hypothesized that transcranial Doppler saline studies would be more sensitive, in part because sedation for TEE could prevent an adequate Valsalva maneuver.
