17-year-old-man who presented with syncope, had a left ventricular (LV) myxoma causing left ventricular outflow tract obstruction. The tumor was removed through left ventriculotomy using conventional cardiopulmonary bypass with good result. There have been 47 cases of LV myxoma reported in the world literature since 1957. Most of them are symptomatic (92.7 %). Systemic embolism is the most common manifestation (50 %) and often leads to death. The surgical removal should be performed urgently. Resection of the mass with limited normal tissue surrounding its pedicle is recommended. There are only three recurrences and five operative deaths.
