A 9-year-old, asymptomatic boy was referred to our centre with a recurrent left ventricular mass. He underwent a left ventricular myxoma resection (7.6 × 4.8 cm) concomitant with edge-to-edge mitral repair 4 years ago in another hospital. Follow-up transthoracic echocardiographs (TTE) revealed a slowly growing left ventricular mass 3 months after the initial operation. Physical examination this time revealed a grade 3/6 systolic murmur best heard at the right upper sternal border and a grade 2/6 systolic murmur best heard at the apex. TTE showed a 6.3*3.2 cm left ventricular mass which was attached to the ventricular septum and protruded into the aorta during systolic cycle (Figure 1A and 1B). A mild to moderate mitral regurgitation was also identified. Cardiac magnetic resonance imaging (MRI) revealed mild delayed hyperenhancement in the mass (Figure 1C and 1D). He had no skin pigmentation or significant family history.
