Signs of Cardiac Injury in Critically Ill Paediatric Patients with COVID-19: a Single-Center Experience in Brazil.

Background: Some patients with COVID-19 present myocardial injury.

Objective: To detect myocardial injury in critically ill paediatric patients, and to compare cardiac involvement between children with severe acute respiratory syndrome (SARS) and children with multisystemic inflammatory syndrome (MIS-C).

Methods: All COVID-19 children admitted to a referral intensive care unit were prospectively enrolled and had a two-dimensional echocardiogram (2D-TTE) and a cardiac troponin I (cTnI) assay within the first 72 hours.

Does sedation influence cardiac magnetic resonance duration for children?

Purpose: The aims of our study were to compare cardiac magnetic resonance (CMR) scan time (time elapsed between first and last acquired sequence) and room time (time elapsed between patients' entrance and exit of the MRI room) between sedated and non-sedated children and to assess the contributing factors.

Methods: It is a cohort study performed at a CMR facility in a tertiary-care center. We compared scan time and room time between sedated and non-sedated children and assessed the influence of gender, age, weight, height, body surface area, number of sequences, and patients' diagnosis/previous procedures.
