Left ventricular myxoma in a child: a case report.

Left ventricular myxoma are quite rare and have not been reported in children. We report a left ventricular myxoma arising from interventricular septum in a 12-year-old girl who presented with history of single episode of syncope while playing in school. General examination of the child did not reveal any abnormality except a grade II/VI systolic murmur in left parasternal area. Transthoracic echocardiography revealed a round pedunculated mass (18 × 30 mm) in left ventricle arising from middle of interventricular septum with a pedicle measuring 4 mm at its base. The tumour was projecting through aortic valve in systole. Syncope in this case was probably due to obstruction of left ventricular outflow tract by myxoma leading to a decrease in cardiac output. Complete excision of myxoma was done through transmitral approach.
