Cardiac point-of-care ultrasound in the paediatric cardiac ICU: assessment of imaging quality and interpretation.

We evaluated quality characteristics of cardiac point-of-care ultrasound performed in our paediatric cardiac ICU. Of 47 included patients, diagnostic imaging was feasible in a high percentage of patients with good image quality. Intensivist interpretations of images were highly specific for dichotomised abnormal findings when compared to interpretation from a cardiologist with expertise in imaging but challenges in accurately assessing depressed ventricular function and the risk of discrepant interpretations exist even amongst frequent users with extensive training and experience. These findings may serve as a template for continued development of cardiac point-of-care ultrasound in a high-impact clinical environment.
