Dr. Schaffer

"Dr. Schaffer was very nice and explained the robot-assisted valve replacement. Surgery was good. 6 days in hospital. Thought I would recover a little sooner. Today is 5 weeks, I am walking 3 miles per day and back at the gym working with minimal weights."

-- Robert Keith, Aortic Valve, Valve Replacement, Robotic Surgery, 06/10/2025

"Doctor Schaffer performed Open Heart Surgery (OHS) on me June 2, 2025 for Aortic Valve Replacement. The Doctor explained in detail the work that was going to be accomplished and what to expect after surgery. On surgery day preparation, the Nurses, Anesthesiologist and staff were great and everything went extremely well.

After surgery, I was sore but was never in any pain except for sneezing, coughing etc. The heart pillow is a must during the healing process. Doctor Schaffer did visit while in recovery to see how I was doing and answered questions to our understanding.

I was released on the 4th day after meeting with the Doctor. Recovery at home went better than expected. My chest incision healing went well with no problems. Once again, I had no pain, only soreness as the incision healed and only took Tylenol a few times. The heart pillow is a must while healing and the incentive spirometer to exercise the lungs are a great help (both provided).

I have full faith in Dr. Schaffer if I ever need any more work."
