"I met Dr. Justin Schaffer at The Heart Hospital Baylor, Plano, TX, with his calm, caring demeanor. It was obvious he had studied my records, was prepared to answer my questions, and was a master of the process to correct my issues. We talked. Amazing! A cow's valve. I felt so confident. I immediately knew he was the right doctor for me. Exactly what I needed. Because his confidence and caring chased my fears away.

The results of his expertise and the brilliant ones he chose to assist him was unknown to me because I closed my eyes for 5 1/2 hours. When I opened my eyes, I said, "Is it over?" It seemed so quick. I had no pain. They said they "stayed ahead of the pain." That proved to be true.

In a private ICU room, I was given a red heart-shaped pillow to remind me that I had to protect my incision. I also recalled how quick it seemed to me from the time my family brought me to The Heart Hospital where we were met by the free valet service. The front desk receptionist was cheery and welcoming. I felt at home.

All of the staff members, I thought, were handpicked just for me. So kind, so educated, so skilled, so personable, and each one signed my red pillow that I am looking at now remembering that it all seems like a dream that happened 12 weeks ago. I stayed 8 days in the hospital among so many kind, loving, nurses.

I feel better everyday. Everything has gone well with no issues. Thank you, Dr. Justin M. Schaffer for your magnificent success with my complicated heart issues. For such a critical time in my life, this was the most perfect experience I have ever had from all who provided me care, and I felt no fear. My family was grateful for calls from the operating room to tell them the progress during the 5 1/2 hours they waited. Thank you for saving my life, and for my Heart-to-Heart pillow to remind me."
