Dr. Klewer, a professor in The University of Arizona Department of Pediatrics, is a 1991 graduate of the UA College of Medicine. He completed his pediatric residency and a fellowship in pediatric cardiology at the University of Iowa. He is board certified in pediatric cardiology.
Dr. Klewer’s specialty is providing medical care to children with heart problems, and his particular expertise is in the non-invasive imaging of the heart. In addition to caring for patients and teaching medical students and residents, Dr. Klewer is an active researcher in the Sarver Heart Center and the Steele Children’s Research Center, where he is an associate director. He and his research team currently are investigating bicuspid aortic valve (BAV), the most common congenital heart defect, affecting about 3 percent of the population.
His research topics include:
Molecular and genetic analysis of cardiovascular development with an emphasis on role of the extracellular matrix in heart valve formation and blood vessel morphogenesis.
Molecular pathways directing normal and abnormal heart valve development in order to improve the diagnosis and repair of severe congenital heart defects and to understand the development of the human heart, to understand at what point the heart can begin to develop abnormally. Of particular concern are babies who are born with Down syndrome as nearly half of these babies also are born with significant heart defects.
