"Dr. Marc Gerdisch’s bedside manner was impeccable. All of my questions were answered before and after my mitral valve repair."

-- Angie Gregory, heart valve surgery patient

"After a false positive for autoimmune hemolytic anemia and told to take steroids following open heart AVR 22 May, 2018 to rid the problem, I got a second opinion & it was found that I had a leak in the new valve destroying red blood cells. I had records changed over and a consult with Dr. Gerdisch. It was determined after cath that the sure way to fix was a redo of the aortic valve replacement. On August 21, 2019 I was fortunate enough to have Dr. Gerdisch do the Open Heart procedure and redo the 1st valve replacement.

My stay in the hospital was 4 days. After 4 days home I was released by visiting nurses and within a week was back on the treadmill. What a different experience! With Biomet plates instead of wire holding chest together I was able to move arms and exercise. Not to mention being able to sleep. I have not taken the first pain pill and am now after 3 weeks back up to 7 miles 4 days a week. No 18 wks. rehab or physical therapy like last time. I can not thank Dr. Gerdisch, his staff and Franciscan Hospital and nurses there for taking all the fear out of my experience. From my personal view, I can honestly say I now know the difference in procedures and if I ever need anything done, my hope is that Dr. Gerdisch and his staff will take my case on."
