Transcranial Doppler vs. Echocardiography: A Comparative Study in the Evaluation of Right-to-Left Shunt
February 23, 2023
9:00AM Pacific

The aim of this webinar is to understand the utility of transcranial Doppler studies compared with echocardiography in the screening evaluation of patients with a right-to-left shunt, most commonly associated with a patent foramen ovale (PFO).

New Successful Stroke Workflow Using Robotic TCD to Screen for Right-to-Left Shunt in the Evaluation of Cryptogenic Stroke at a Large Comprehensive Stroke Center

This webinar highlights the recently published study that evaluated 100 patients who received a newly implemented robot-assisted transcranial doppler (rTCD/NovaGuide) with bubble injection. It was used to find right-to-left shunts (RLS) as a potential cause of stroke in young patients, as defined by age <65.

The study objectives included:

  1. Determining feasibility of implementing rTCD in the evaluation of etiology in acute ischemic stroke patients.
  2. Determining the rate of RLS detection in patients who had rTCD bubble testing compared to established rates using TTE bubble studies.
  3. Reviewing the distribution of the Spencer scale in grading RLS size as a factor in the resulting medical management and PFO closure.

The Latest Guidelines for Transcranial Ultrasonic Monitoring

Transcranial Doppler is an extremely effective tool for intraoperative neurophysiologic monitoring that can result in better patient outcomes and decreased length of stay. In this webinar, you will learn the recently updated guidelines from the American Society of Neurophysiologic Monitoring and American Society of Neuroimaging for the use of TCD in the surgical and intensive care settings.
