  • Title: Recurrent hemiparesis due to anterior mitral leaflet myxomas.
    Author: Omeroglu RE, Olgar S, Nisli K, Elmaci T.
    Journal: Pediatr Neurol; 2006 Jun; 34(6):490-4. PubMed ID: 16765831.
    Abstract:
    Strokes, cardiac or noncardiac, generally affect the elderly and only occasionally occur in children. A tendency to stroke occurs in cyanotic congenital heart disease; however, this report describes two female patients, aged 6 years and 4 years, who had no cyanotic disease. The first patient was admitted to the hospital after the first stroke but suffered a second one after admission. Her initial cardiac examination was normal. The other patient was admitted after a second right-sided hemiparesis. A mild pansystolic ejection murmur was observed at the lower left sternal border on auscultation; slight late diastolic murmurs with opening snap were found in the mitral valve area, and the second heart sound was increased. Transthoracic echocardiography revealed a mass in the anterior mitral valve in both patients. These masses were completely removed surgically and pathology revealed myxomas. Hemiparesis completely resolved after surgical and medical treatment. The clinical manifestations of cardiac tumors primarily depend on their number, size, location, and histology. Strokes and anterior mitral valve masses are extremely rare in children. In the two cases reported here, anterior mitral valve myxomas caused systemic embolization as a result of their location. Echocardiography should be performed early in patients presenting with recurrent strokes to exclude such pathology.
