Study should ‘dramatically change’ practice
Commenting on the study, Patrick Lyden, MD, professor of physiology and neuroscience and of neurology, University of Southern California, Los Angeles, said: “Most clinicians hesitate to use transcranial Doppler given the need for specialized technical expertise to obtain a reliable result. This study showed that a robotic transcranial Doppler device – which can be applied by any cardiac non-invasive lab technician – provides reliable and rigorous data.”
He added: “This result will dramatically change the typical evaluation of patients with suspected PFO: In place of an invasive transesophageal echo that requires anesthesia and a cardiologist, most patients can have a non-invasive, robotic-guided transcranial Doppler and get the same diagnostic benefit.”
Dr. Lyden also pointed out that the cost of TCD is typically one-tenth that of TEE, although he said the cost of the robotic guided TCD “is not clear.”
A representative of the company that makes the robotic assisted device, NovaSignal, says the cost of the equipment is approximately $250,000, but “understanding the importance of the technology, we work with each hospital to meet their unique needs.”
The company adds that it currently has “over 45 commercial solutions deployed across 25 centers with 3-4 times growth expected year over year.”
The study was supported by NovaSignal, the company which makes the robotic device. Dr. Rubin reports acting as a consultant for the NovaSignal.
