Adult Congenital Heart Disease (ACHD) Fellows
Paulina Arista, MD, MHA
1st Year
Paulina Arista was born in Mexico and raised in Chicago, Illinois. She earned her BS in Biology from Loyola University Chicago and her MD from the University of Medicine and Health Sciences in Saint Kitts and Nevis in 2018. She completed a combined Internal Medicine and Pediatrics residency at the University of Missouri Health Care, where she served as chief resident. She subsequently completed her pediatric cardiology fellowship at the University of Mississippi Medical Center. Her prior research focused on transition care in congenital heart disease, with particular attention to the role of social determinants of health within Mississippi’s adult congenital heart disease (ACHD) population. During her ACHD fellowship, she plans to shift her research focus to cardio-obstetrics, reflecting her growing interest in the intersection of women’s cardiovascular health, pregnancy, advanced cardiac imaging and congenital heart conditions. Outside of medicine, she enjoys working out, trying new restaurants, and spending time with her family and Irish doodle.
