Patient Care Location



Katherine (“Katya”) is a board-certified pediatric cardiologist with expertise in cardiac imaging and fetal cardiology. After obtaining her medical degree from Ross University, she completed her pediatric residency at the Children's Hospital of Illinois and her pediatric cardiology fellowship at Arkansas Children's Hospital. She then went on to complete an advanced imaging fellowship at UCSF Benioff Children's Hospital where she trained with international experts in fetal cardiology.

During her fellowship, she investigated outcomes of congenital heart surgery in patients with trisomy 13 and 18. That work culminated in an important publication highlighting that congenital heart surgery improves in-hospital mortality in children with trisomy 13 and 18 (Kosiv et al, Pediatrics, 2017). She continues to engage in research with her mentor to devise recommendations for congenital heart surgery in trisomy 13 and 18. In addition, Dr. Kosiv has investigated the effect of congenital diaphragmatic hernia on the fetal heart and fetal brain and continues to be interested in the effects of non-cardiac diseases on the fetal heart such as in twin-twin transfusion syndrome and lower urinary tract obstruction. She is currently planning an investigation of the genetic predictors of left sided obstructive heart diseases such as hypoplastic left heart syndrome and aortic stenosis. She hopes that with this information in hand, cardiologists will be able to better predict which patients will go on to develop severe left sided obstruction.
