Beginning this past summer, I have been grateful for the opportunity to conduct research under the mentorship of Dr.?Jonathan Dillman in the Cincinnati Children’s Hospital Radiology department. This work has intersected my current interests in pediatric radiology, pediatric cardiology, and artificial intelligence.
My research project focuses on pediatric patients born with only one pumping chamber, or ventricle, in the heart instead of two pumping chambers. In most cases, children with single-ventricle heart defects require intensive medical intervention shortly after their birth. The Fontan procedure is?a type of open-heart surgery performed in these patients to avoid overworking the single ventricle in pumping blood to the entire body. The surgery allows venous blood returning from the body to enter the lungs by direct blood vessel connections that avoid passing through the single ventricle. However, because of the rerouting of blood in these patients, elevated pressures in the veins can lead to Fontan-associated liver disease, which has become an increasing cause of morbidity and mortality in these post-procedure patients.
The goal of my research project has been to develop machine learning models using MRI images of the liver as well as clinical data from post-Fontan patients to predict future clinical outcomes in these patients within two years of their MRI examination. Some clinical outcomes we have studied include the need for cardiac transplantation or a ventricular assist device, elevated liver stiffness, and the presence of portal hypertension. Because of the high prevalence of Fontan-associated liver disease, we hope this research can ultimately provide both radiologists and cardiologists with surveillance strategies during childhood for patients with Fontan circulation. I look forward to continuing to work with Dr. Dillman and the research team to refine our machine learning models and be able to one day provide patients and their families with the best diagnostic performance.
