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.
