My Dad had a triple bypass done by Dr. Guo in 2016. When I was diagnosed with a bicuspid aortic valve I was referred to University Hospital (London, Ontario) and requested for Dr. Guo. I had my 1st consultation with Dr. Guo in November 2021, when I first got into the room I wanted to cry due to an overload of emotions but by the time I was done listening to him and asking questions I walked away feeling so at ease. Dr. Guo and the Team at University Hospital are the absolute best. Now on to the next step ... scheduling my surgery. No doubt in my mind this is the absolute best place to be with the absolute best care possible. I will be back to post my experience once I have completed the next step.

On Feb 8, 2019 Dr, Guo and his team replaced my aortic valve (tissue) and did a triple bypass on me. On Feb 13 I walked out of the hospital, by Feb 20 I was walking around the block. On June 7th I started playing ice hockey again. I am 75 and able to do physical things I had difficulty doing for years. Now nearly eight months after my surgery I couldn't be more please with the outcome. Thank you Dr. Guo and the whole team at the University Hospital in London, ON.

I had 3 valve replacements, Aug 18, 2017, 2 mechanical and 1 tissue, it was by far an extremely difficult surgery, Honestly I was prepared to not come out of it. With Dr. Guo and other surgeons and nurse staff I not only made it through, I also recovered from it pretty fast. I am totally amazed at how brilliant the Heart Surgeons at University Hospital are. How caring and efficient all the nurse are. I thankyou all for my second chance at Life!
