Pediatric cardiac catheterization

Abstract

The publications of 2000 and 2001 stress how interventional pediatric cardiology has moved from angioplasty to device placement. This review summarizes the important articles during the past year that evaluated the safety and efficacy of atrial septal defect devices, patent ductus occluders, and stents to treat coarctation of the aorta. The past year has also seen the emergence of old technologies that have been modified and expanded for new applications. The three areas of old technology reviewed are (1) using balloon angioplasty to palliate low birth weight infants with critical coarctation, (2) using coronary interventions in the pediatric patient, and (3) using balloon pulmonary angioplasty to treat patients with chronic thromboembolic pulmonary hypertension. Finally, this review describes the development of a new interventional technique, transcatheter implantation of a pulmonary valve, and outlines how real-time MRI in the next decade likely will replace x-ray fluoroscopy as the primary diagnostic and interventional imaging tool for the pediatric cardiologist.
