The AI Now in the Operating Room During Heart Surgery

Philips' FDA-cleared AI guides mitral valve repair in real time, easing cognitive load and raising the bar for US cardiac labs

29 May 2026

On a beating heart, seconds matter and attention frays. Until recently, two operators inside a cardiac suite had to read separate ultrasound and X-ray screens while steering a repair device through one of the heart's most delicate valves. The coordination demanded was considerable. The margin for error was not.

Philips changed that calculus on March 26th, when the FDA granted 510(k) clearance to EchoNavigator R5.0 with DeviceGuide, an AI platform built to guide physicians through minimally invasive mitral valve repair in real time. Developed with Edwards Lifesciences, it targets a procedure called M-TEER, used to treat mitral regurgitation, a condition affecting more than 35 million people worldwide.

The software fuses live echocardiography from Philips' EPIQ CVxi with X-ray imaging from its Azurion platform, producing one integrated view and tracking the repair device automatically throughout. First-in-human findings, published in JACC: Case Reports, documented improved team coordination and a measurably reduced cognitive load during procedures. For US centers running the Edwards PASCAL Ace programme, consistent outcomes may now be achievable across teams of varying experience.

Limits remain. Clearance covers use with the PASCAL Ace system only. Broader deployment requires further regulatory submissions.

The narrower story, though, matters less than what it signals. Surgical AI has long operated at the margins, in planning tools, post-procedure analytics, and outcome monitoring. Placing machine intelligence inside the procedure itself, fusing data streams in real time as an intraoperative guide, marks a genuine departure from where the field has concentrated its effort.

As transcatheter structural heart programmes spread nationally, intraoperative navigation may become the next frontier of standardisation. Philips and Edwards have cleared the first gate. Many more lie ahead.
