Abstract:
Given their cognitive and developmental status, sedation is frequently required for procedural imaging in infants and children. Although generally free of adverse effects, the agents used for procedural sedation may impact airway, hemodynamic, and respiratory function, especially in the presence of comorbid cardiac involvement. We present the use of the novel benzodiazepine, remimazolam, administered by continuous infusion and supplemented with intermittent bolus doses of ketamine to provide sedation during computed tomography angiography in a 16-month-old girl, who presented with myocardial dysfunction related to a primary cardiomyopathy. Previous reports of remimazolam administration to patients with underlying comorbid cardiac disease are reviewed, and its applications in this scenario are discussed.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
