Division of Cardiology

The mission of Saint Louis University's Division of Cardiology includes providing comprehensive patient care, actively participating in medical student and resident teaching and exploring research questions related to cardiovascular diseases in neonates, children, adolescents and adults with congenital and acquired heart disease.

The Dorothy and Larry Dallas Heart Center at SSM Health Cardinal Glennon Children's Hospital, where our division is centered, opened in early 2009 and underwent a significant expansion in 2016. Radiology (including CT and MRI) and laboratory facilities are located adjacent to the Dallas Heart Center, centralizing outpatient cardiology care within the medical center.

Clinical Services

Outpatient cardiology clinics at the Dorothy and Larry Dallas Heart Center are held on a daily basis. In addition, outreach clinics provide services to other areas in central and eastern Missouri as well as southern Illinois, providing pediatric cardiology support to those areas that are without local expertise. Echocardiography services are provided primarily at SSM Health Cardinal Glennon Children’s Hospital, and an active telemedicine program exists providing interpretation of echocardiograms that are transmitted from numerous other facilities in Missouri and Illinois.

A hybrid cardiac catheterization lab/operative suite was opened in July of 2011 and is the only such catheterization suite in the region for pediatric patients. This technology allows unique procedures involving interventional catheterization techniques combined with cardiac surgical intervention to be carried out in the same setting when indicated. Typical procedures also performed in the Cardiac Catheterization Laboratory include diagnostic catheterizations as well as the complete spectrum of interventional and therapeutic procedures, including balloon valvuloplasty, stent placement, device closure of anatomic defects, and percutaneous pulmonary valve placement.

A state-of-the-art electrophysiology lab houses equipment for performing computer-assisted electrophysiologic studies and catheter ablation procedures. This technology allows the majority of procedures to be performed without the use of fluoroscopy. Treatment of complex rhythm disorders and pacemaker therapies are also available.

Specialized cardiac imaging (cardiac CT and MRI) is performed in the imaging center connected to the Dallas Heart Center.

Inpatient services include management of patients admitted with congenital and acquired cardiac conditions, cardiac consultation and postoperative management of congenital heart disease.

The Cardiac Transplantation Service evaluates candidates for transplantation and manages these patients before and after cardiac transplantation. Mechanical cardiac support technology is available as a bridge to transplant when indicated.

Fetal cardiology care is provided through the Dallas Heart Center as well as the adjacent Fetal Care Institute at SSM Health Cardinal Glennon Children’s Hospital, with support from neonatology, perinatology, pediatric surgery and cardiovascular surgery.
