Hello....yes, there is a "normal" rate of growth of 1mm per year to a "concerning " size of 5.0-5.5cm, at which time surgery may be considered. The rate of growth should be monitored by CT scan or ultrasound(echocardiogram). If growth is rapid over a short period, early intervention may be needed. While there are standard approaches taken, each person and case is unique, and shouldn't be pigeonholed. You need to be an informed patient not hesitant to ask questions. Get as much information as you can to be an "educated consumer". "Vague" doctors are abundant, so don't settle for blase answers or indifference. You're in charge of your own health....knowledge is power!! Best wishes for staying healthy!!
