Noninvasive Hemodynamic Assessment for Late-Stage Truncus Arteriosus Management.

A 7-year-old girl with unoperated truncus arteriosus arrived in Finland as a refugee. In contrast to our previous practices, hemodynamic assessment was made using cardiovascular magnetic resonance instead of cardiac catheterization. During the 2-year follow-up period, the right ventricular pressure was estimated to be 50% of systemic pressure in echocardiogram evaluations.
