Pediatric left atrial myxoma: surgical excision and mitral valve plasty.

This report describes the case of a 12-year-old girl with a giant left atrial myxoma who presented with severe mitral regurgitation symptoms. Echocardiography demonstrated a 69 x 30 mm solid mass in the left atrium (LA), occupying almost the entire mitral orifice. After successful surgical excision of the tumor, concomitant with mitral valve plasty, there was no clinical or echocardiographic recurrence at 12-month follow-up.
