Abstract:
Left ventricular (LV) myxomas are rare. We present a case of a LV myxoma arising from the interventricular septum of the LV outflow tract in a 76-year-old woman. General examination of the patient did not reveal any abnormality except for a grade 3/6 systolic murmur in the left parasternal area. Transthoracic echocardiography revealed a round pedunculated mass (size, 23 mm × 11 mm × 10 mm) at the interventricular septum with a broad pedicle. The mass was successfully removed and was pathologically confirmed to be a myxoma. <Learning objective: This is the rare case of left ventricular (LV) myxoma arising from LV outflow tract, which was pathologically confirmed.>.
