Advancing Aortic Research Through Global Collaboration

Research & Registry

Transforming scientific discovery into meaningful outcomes for patients and families is central to MAC’s mission. By prioritizing knowledge translation, MAC ensures its research reaches beyond academic journals to the clinicians, researchers, guideline committees, and families who need it most.

Our Ethos

The Montalcino Aortic Consortium (MAC) formed in 2013 around the need for international cooperation in the study of human diseases, largely determined by variation in genes, that affect the aorta and its major branches.

Featured perspective

Dianna M. Milewicz, MD, PhD

Executive Chair & Principal
Investigator
Montalcino Aortic Consortium

For more than 25 years, Dr. Dianna Milewicz has led groundbreaking research into the genetic causes of aortic disease, helping transform the diagnosis, management, and prevention of Heritable Thoracic Aortic Disease (HTAD). In this featured perspective, Dr. Milewicz discusses how genetic discovery, collaborative research, and precision medicine are advancing patient care worldwide. She also shares the vision behind the MAC and its role in translating data into evidence-based care that helps prevent aortic dissections and save lives.
