Dr. Killen is a pediatric and fetal cardiologist with expertise in fetal arrhythmias and prenatal diagnosis of complex congenital disease. Her clinical and research efforts seek to improve the care of mothers and fetuses whose pregnancies are complicated by fetal arrhythmias. Dr. Killen has published articles on fetal supraventricular tachycardia, fetal long QT syndrome, and fetal immune-mediated carditis/SS-A antibody-mediated congenital heart block. She has also participated in research projects focused on prenatal evaluation of and postnatal outcomes in special, high-risk populations with hypoplastic left heart syndrome (Turner syndrome, restrictive atrial septum, and coronary fistulae), the findings of which influence both prenatal counseling and postnatal management. Dr. Killen is currently participating in several multi-center studies, including studies sponsored by the Fetal Heart Society, that seek to improve treatment approaches and outcomes for patients with fetal arrhythmias and complex congenital heart disease. Based on her research, Dr. Killen has created institutional practice guidelines for diagnosis and management of fetal arrhythmias. She has also created patient education materials on fetal supraventricular tachycardia, fetal heart block, and fetal premature atrial contractions. An interest in feeding and nutrition in infants and children with congenital heart disease prompted Dr. Killen to evaluate how outcomes changed in newborns undergoing surgery for congenital heart disease (CHD) after implementation of a multi-interventional nutrition program, including pre-operative and post-operative feeding algorithms. She obtained grant funding from the Gerber Foundation and found that a multi-interventional nutrition program was associated with improved weight gain, fewer gastrostomy-tubes, and increased pre-operative enteral feeding without increases in necrotizing enterocolitis, hospital stay, or mortality. Dr. Killen is passionate about educating pediatric residents, pediatric cardiology fellows, fetal cardiologists, obstetricians, and perinatologists on the diagnosis and management of fetal arrhythmias and has given presentations on these topics at a variety of educational forums. She is a member of the American Society of Echocardiography and the Fetal Heart Society.
