Dr. Stefanescu and her team, including a number of different doctors, have worked on my heart and I appreciate that. They've re-plumbed it. They've reworked the electricity and I am making a level of progress that I did not believe possible. Stefanescu and co. are terrific. Thank you.

This was my introductory appointment with Dr. Stefanescu, I was referred by my Cardiologist at Wentworth Douglass Hospital in Dover, NH. I have an aging Aortic valve, functioning for 15 years and a recent diagnosis of a pulmonary valve, both are regurgitating. I first had a CT scan prior to my appointment with Dr. Stefanescu. She carefully reviewed the results of the CT scan as she explained the details of the images that were displayed on the screen. I was impressed with her knowledge of the complexity of my condition as she needed to decide on the best plan for moving forward comparing the functions of the two valves.

I would like to express in my words thanking the congenital heart department and MGH for their tireless care, diligent service, and profound knowledge. Based on my experiences during the last two years, the staff and Mass General Hospital, especially Dr. Ada Stefanescu, are the finest professionals a patient could have in this country. They are the corner stones and building blocks of your fine institution. Keep up the great we, we need you.

My doctor is always wonderful. She is very clear on what she feels I need to do to take care of my condition. Her MA, name began with a V, was amazing. She was efficient and effective without losing the personal touch. We had a great conversation while she moved through taking my vitals. Her happy and warm demeanor is an asset to the office. I'd love her to know I appreciated how we interacted.
