Point-of-Care Ultrasound echocardiography diagnosis of an atrial myxoma in a child presenting with stroke

Abstract

We describe a case of paediatric stroke secondary to atrial myxoma, diagnosed in the Emergency Department by Point-of-Care echocardiography. A previously fit and healthy teenage male presented to our paediatric emergency department following a collapse with loss of consciousness. He had suffered a stroke, and had facial paralysis and hemiplegia. His cardiac examination revealed a 3/6 ejection systolic murmur. Whilst his CT was being reported, he had a Point-of-Care echocardiogram in the resuscitation room which showed a very large mass arising from the left atrium and occupying >50% of the chamber. A piece of the myxoma had detached and caused the stroke. The patient was rapidly transferred to a cardiac intensive care unit and underwent emergency surgery the same day. His tumour was successfully completely resected, and he has only a mild residual hemiplegia. Cardiac myxoma should be considered in any child who presents with unexplained acute stroke and a cardiac murmur. Point-of-Care Ultrasound echocardiography in the Paediatric Emergency Department can be used to make a life-saving diagnosis, enabling early surgical management and preventing lifelong complications in children.
