"I was referred to Dr Kathryn Harrington by my cardiologist . Dr Harrington answered all my pre and post surgery questions. She is a very confident and smart surgeon. My recovery was quick and I was able to get back to work after my 3 weeks post surgery follow up visit. I will say that Dr Harrington is a great tool in Gods hands and I cant recommend her enough. "

"Dr. Harrington performed 3 procedures on my heart. My surgery took close to 6 hours @ The Heart Hospital-Baylor in Plano, TX on 1/21/2019. I am post-op almost 2 months, making an excellent recovery with no complications. (Beginning cardiac rehab shortly.) Her bedside manner, knowledge & professionalism were outstanding. At my post-op visit, I thanked her for saving my life. I would highly recommend Dr. Harrington."
