Glad I have found this group. Mine was also found while following afib cryoablation and low left ventricle ejection fraction with echocardiogram and zio patch every 6 months. April 2023 ascending aorta was 3.1 cm, October echo and follow up ct scan was 3.8 cm. My research and Doctors tell me that is small but I worry about the quick enlargement. Next echo is to be done in March. In the mean time I trying to stay calm and looking for future options in California. I appreciate the information I'm getting from you all!
