Dr. Schaffer

"I had a surgical aortic valve replacement (SAVR) re-operation. I am highly satisfied with the whole experience!"

-- Randy Stephens, Aortic Valve, Valve Replacement, 12/09/2026

"Dr. Schaffer was great to deal with. He was very informative before and after the surgery. He performed aortic valve replacement on my bicuspid aortic valve that had severe stenosis. I was very lucky to find a great robotic surgeon close to home.

The procedure went great and I was walking 2-3 miles within a week of surgery. The staff at Baylor Heart Hospital Plano was awesome. I plan on completing a half marathon within two months of my surgery (most of it will be walking).

I highly recommend Dr. Schaffer and the Baylor Heart Hospital in Plano Texas."
