NeuraSignal

On November 2, we hosted a private cocktail reception at Nobu San Diego for local physicians, most of them cardiologists, with the amazing Dr. Razi Khan as our speaker.

Dr. Khan is an interventional cardiologist at Royal Columbian Hospital, and he shared his center's real-world data on robotic TCD, why TCD is a more accurate way to screen for right-to-left shunt than transthoracic echo, and how easily it fits into a busy workflow.

Thank you to everyone who joined us, and to Dr. Khan for sharing his experience.

Follow @NeuraSignal for more on how centers are using robotic TCD to find shunts that echo misses.

Neurovascular clinicians, see you in two days at the 2026 ANVC Annual Conference at Sun Valley Resort in Sun Valley, Idaho! We bet you'll want to hear what robotic TCD could do for your stroke program, so find us at booth #9. We'll be happy to answer all your questions.

See you soon!

Before LVAD surgery, there's one small finding that can make a big difference after it: a patent foramen ovale (PFO). Once the pump starts working, pressure on the left side of the heart drops. A PFO that caused no problems before can then start sending oxygen-poor blood into the body's circulation, leading to dangerous hypoxemia. If surgeons know the PFO is there, they can close it during the same operation.

A new study in Clinical Neuroimaging looked at how well current screening finds these PFOs. Researchers reviewed 102 patients who received an LVAD at Rochester General Hospital and compared their pre-surgery test results with what surgeons actually found in the operating room.

The results:
→ TTE alone detected 26.7% of PFOs
→ TCD alone detected 33.3%
→ TTE and TCD together detected 43.8%, with specificity still above 90%
→ TCD found 3 shunts that TTE missed, 2 of them large

Every test's sensitivity was lower than published rates. The authors point to several possible reasons, including the strict comparison standard and heart failure itself, which can hide shunts. But their conclusion is still clear: relying on TTE alone risks missing PFOs, and adding TCD is a practical, noninvasive way to catch more of them before surgery.

The study also cites BUBL (Stroke, 2023). In that trial, @NeuraSignal’s robotic TCD system detected right-to-left shunts in 64% of patients with stroke or TIA, compared with 20% for TTE.

We're heading to Sun Valley, Idaho, for ANVC's biggest gathering yet - the 2026 ANVC Annual Conference!

If TCD is part of your work, here are 2 things to add to your plans:

1. Arrive early for the pre-conference workshops on November 12. They include a Duplex & Transcranial Doppler Vascular Imaging session on vasospasm detection, emboli monitoring, and cerebral hemodynamics. There's also a hands-on TCD workshop where you'll practice probe placement, vessel identification, and waveform interpretation.

2. Stop by booth #9 to see @NeuraSignal's robotic TCD, NG2 Intelligent Ultrasound, in action. Watch it find the arteries, stay locked on them, and detect the bubbles automatically.

See you at Sun Valley Resort, November 11-14!

What do you get when you mix Abbott and @NeuraSignal? A great evening of PFO talk. More specifically, a dinner last Sunday in San Diego for structural heart and stroke prevention specialists.

So how did this partnership come about? The two companies cover two halves of the same patient journey:
→ NeuraSignal covers diagnosis with the NG2 Intelligent Ultrasound, which detects right-to-left shunts (RLS) caused by a PFO.
→ Abbott covers closure with the Amplatzer Talisman PFO Occluder, which seals it.

That's where the evening's title came from: "From Diagnosis to Closure: Patient Selection, Device Strategy, and the Role of TCD in Modern PFO Care."

Here's who spoke and what they covered:

→ Dr. Nicholas Ruggiero (@DrNickTJU), Senior Medical Director at Abbott, opened the evening and welcomed the guests.

→ Dr. Razi Khan, interventional cardiologist at Royal Columbian Hospital, showed how robotic TCD finds far more PFOs than transthoracic echo, and shared his center's real-world experience.

→ Dr. Barry Love, Director of the Congenital Cardiac Catheterization Laboratory at the Icahn School of Medicine at Mount Sinai (@IcahnMountSinai), reviewed the latest PFO closure evidence and explained how he chooses a device. He also described how his program grew by building heart-brain working groups with neurology.

The common thread was that PFO care works best when cardiology and neurology work together - neurologists find the patients, cardiologists close the PFOs, and fewer people go on to have a second stroke.

Thank you to Abbott and to Drs. Ruggiero, Khan, and Love for an insightful evening!
