After careful and thoughtful deliberations, and given the rapid developments around the spread of COVID-19 ─ including travel bans by many institutions preventing presenters and members from attending, as well as the State of Emergency declaration in New York ─ the AATS Aortic Symposium and AATS 100th Annual Meeting will not take place in April 2020. The health, safety, and well-being of our attendees, members, exhibitors, staff, and vendors are of paramount importance. We ask for patience as we evaluate our next steps and all possible options. More information will be communicated as it becomes available. We thank you for understanding the extreme complexity of this decision and for your commitment to the success of these AATS meetings.
