INTERVENTIONAL CARDIOLOGY AND ELECTROPHYSIOLOGY
RESEARCH HIGHLIGHT
The interventional cardiologists at Riley Children’s Health have expertise in using the latest invasive, catheter-based procedures to diagnose and treat congenital heart conditions. Part of an elite cardiology program, our skilled specialists provide essential anatomic evidence during diagnostic procedures to direct cardiovascular surgical interventions. They also repair heart conditions, such as patent ductus arteriosus, atrial septal defect and ventricular septal defect that allow both children and adults to avoid open heart surgery.

in continuous quality improvement. It sets Riley Children’s apart as a premier program for cardiovascular procedure-based modalities. IAC has recognized Riley Children’s in the following areas: ■ Cardiac electrophysiology – Device implantation and testing, and ablation ■ Cardiovascular catheterization – Complex adult congenital heart disease, pediatric cardiovascular catheterization and valve interventions
■ Pediatric cardiac catheterization lab accredited by the Intersocietal Accreditation Commission (IAC)

Riley interventional cardiologists continue to conduct high-intensity procedures with radiation exposures that are below the national average.
■ One of only eight pediatric facilities nationwide accredited by IAC in cardiac electrophysiology and one of only six in cardiovascular catheterization

Riley Children’s was one of the first children’s hospitals in the nation to routinely treat PDA in premature infants through cardiac catheterization. Our team now performs 20 to 30 closures per year in babies as small as 700 grams.
