A surgical robot just performed one of the world's most common heart operations through tiny cuts between the ribs

At a California hospital, a da Vinci robot helped a surgeon bypass blocked heart arteries without cracking open the chest. The patient was walking the next day.

Key points

  • Coronary artery bypass surgery, the world's most common cardiac operation, is performed robotically in fewer than 1% of cases globally.
  • Dr. Nels Carroll at El Camino Health Heart and Vascular Institute in California performed the first robotic bypass procedure at the hospital using Intuitive Surgical's da Vinci system.
  • Patient Raul Martin, 64, was walking hospital corridors the day after his robotic bypass and went home within a couple of days.
  • Robots let surgeons work through small cuts between the ribs instead of sawing through the breastbone, cutting recovery time and pain sharply.
  • Surgeon shortages, training gaps, and simple habit explain why robotic bypass remains rare despite the benefits.

Every year, hundreds of thousands of people need a coronary artery bypass, a procedure to reroute blood around a blocked artery in the heart. It works. It saves lives. It also requires surgeons to saw through the breastbone, pull the chest apart, and stitch it back together with steel wire. Recovery takes weeks and hurts a lot.

Now a team in California is doing the same operation through cuts no bigger than a finger-width.

What actually happened?

Surgeons at El Camino Health Heart and Vascular Institute in Mountain View, California, began performing robotic-assisted coronary artery bypass grafting, known as CABG (pronounced "cabbage"), using Intuitive Surgical's da Vinci system, a robotic platform whose thin arms hold tiny instruments and a camera. The first case was led by Dr. Nels Carroll, one of the few surgeons in the San Francisco Bay Area trained in this technique, as first reported by The Robot Report.

Carroll uses a plain analogy to explain what goes wrong in these patients. The heart is an engine. The arteries wrapped around its surface are fuel lines. When those fuel lines fur up with disease, bypass surgery replaces them. "We're just putting on new fuel lines," he said.

The hard part has always been getting to the engine.

"The most challenging thing for the patient is that, historically, we have to cut their chest open," Carroll said. With the da Vinci system, that changes. Instruments and a camera slide in through small cuts between the ribs. No bone is divided. No major muscle groups are cut.

What did this mean for a real patient?

Raul Martin, 64, walked three to five miles a day and lifted weights regularly. One Sunday at the gym, his smartwatch alarmed him: heart rate 200. A security guard called paramedics. Martin ended up at El Camino Health, where Carroll performed a robotic bypass.

The morning after surgery, Martin was up and walking the corridors. He went home a couple of days later and returned to his normal routine.

That speed is the point. Recovering from small cuts between ribs is a very different experience from waiting for a sawn sternum to knit back together with steel wire.

Why aren't more hospitals doing this?

Fewer than 1% of bypass operations worldwide use a robot, and the reasons are practical.

Factor Detail
Patient selection Some cases still need full chest access; robots don't suit every anatomy
Surgeon training Very few cardiac surgeons have learned the technique
Referral gaps Cardiologists and GPs often don't know robotic bypass exists
Habit Surgeons proven in conventional methods are cautious about switching

Carroll compares adopting a new surgical approach mid-career to changing tactics mid-battle. Once something works reliably, human nature pulls you back to it. The flip side, he notes, is getting stuck.

Robots also help the surgical team, not just the patient. Carroll says a clear shared camera view means everyone in the theatre sees exactly what is happening, which speeds up training for junior surgeons. And physically, he says a long robotic day leaves his back and neck in far better shape than a conventional one.

Common questions

Is this available everywhere?

No. Robotic cardiac bypass is offered at only a handful of centres in the United States, and the number of surgeons trained in the technique remains very small. Ask your cardiologist whether a centre near you offers it.

Does the robot operate by itself?

No. The da Vinci system is a tool controlled in real time by the surgeon, who sits at a console and moves the instruments precisely. No AI is making decisions; the surgeon is.

Should patients push their doctor to consider this?

If you or someone you know needs bypass surgery, it is worth asking whether a minimally invasive or robotic approach is suitable. Not every patient is a candidate, but the question is always worth raising.
