Cardiovascular magnetic resonance imaging in congenital heart disease as an alternative to diagnostic invasive cardiac catheterization: A single center experience

Abstract

Objective: The study aims to assess whether the increasing use of cardiovascular magnetic resonance imaging in place of diagnostic cardiac catheterization in the management of pediatric patients with congenital heart disease has had an impact on pediatric cardiac care. Design: Retrospective analysis of data was used. Setting: The study was performed at the Evelina Children's Hospital Cardiology Department. Patients.: Elective diagnostic cardiac catheterization or magnetic resonance imaging (MRI) from 2005-2010 are included (n = 896). Outcome Measures: Indication, length of stay, and incidence of complications were recorded. In cases used to plan surgery, 30-day survival following the procedure was recorded. Surgical outcomes were compared between the two groups. Surgical outcomes planned using MRI were compared with national outcomes from Congenital Cardiac Audit Database. Results: For catheterizations (50 patients, [31 male, median age 3 years, interquartile range 1 to 12]), median hospital stay was 1 day (interquartile range 0 to 3), and complications occurred in 11 (22%). Median hospital stay for MRI (846 patients [517 male, median age 3 years, interquartile range 0 to 9]) was significantly shorter: 0 days (interquartile range 0 to 1, P
