“…SVT can cause intracardiac thrombosis in the left-side of the heart. [9][10][11][12] The proposed mechanism of thrombosis is stasis of blood flow in the setting of poor contractility or enlargement of the left atrium or ventricle. 5,9,10 Aside from the patient with left ICA narrowing, all children with SVT and subsequent stroke had atrial enlargement and/or ventricular dysfunction on echocardiogram.…”

We report a rare case of cardioembolic stroke in the setting of supraventricular tachycardia (SVT) in an infant. After a week of irritability, a 10-week-old male presented to the emergency department with SVT requiring treatment with adenosine. He developed right-sided hemiparesis and focal motor seizures. Imaging of the brain showed ischemic infarct in the left middle cerebral artery (MCA) territory. Echocardiogram showed a newly formed large left atrial intracardiac thrombus. A coagulopathy workup was negative. He was treated with beta-blocker and anticoagulation therapy. He had mild residual right hemiparesis. During childhood, he developed medically refractory focal epilepsy from the left hemisphere, requiring epilepsy surgery at age 10. A child presenting with sustained SVT can be at increased risk for intracardiac thrombi and stroke.
