We present a case of a teenage patient with new-onset cardiac symptoms discovered to have primary pulmonary arterial hypertension. Point-of-care ultrasound used early in the patient's presentation identified significant right-sided heart dilatation and dysfunction despite the patient's relatively unrevealing physical examination. This article emphasizes the utility of performing focused cardiac ultrasound in pediatric patients early in their presentation. We briefly review focused cardiac ultrasound technique and highlight relevant literature.
