I had open heart surgery on 2.27.2013 and received a 23mm ON-X Aortic Valve and had a total Maze procedure performed. My surgery was performed by the incredibly skilled hands of Dr. Marc Gerdisch. While I do not yet feel "normal", I am amazed by the progress that I have been able to make. I was able to walk (2) miles today. I am excited that I will begin cardiac rehab next week.
