Dr. Harrington

"After extensive research on trying to find my surgeon I selected Dr. Harrington. She is highly recommended. What a blessing she was before, during and after my surgery. Fully understanding I would need an aortic root replacement I was also expecting an aortic valve replacement as well. When most surgeons would have just replaced my valve Dr. Harrington was able to repair my valve with her excellent skills. This is a big deal which means the I have a high percentage of never having to have surgery again. Skills are excellent!"

"After extensive research trying to find my surgeon I selected Dr. Harrington. What a blessing she was before, during and after my surgery. Fully understanding I would need an aortic root replacement, I was also expecting an aortic valve replacement as well. Dr. Harrington spent extra time was able to repair my valve with her excellent skills.....which means I have a high percentage of never having to have open heart surgery again. Her explanation of the procedure, bedside manners and follow up were awesome. She certainly looked out for my best interest and health. I would highly recommend Dr. Harrington and the Baylor Heart Hospital to anyone having heart surgery. Four weeks later I’m able walk two miles and my heart is getting stronger every day. I am blessed to have Dr. Harrington and her team on my side. Truly God sent!"
