Supravalvular mitral stenosis is a rare congenital anomaly. A case of a 2-year-old girl with supravalvular mitral stenosis and ventricular septal defect was successfully treated. The preoperated echocardiogram showed supravalvular mitral stenosis associated with congenital mitral stenosis and ventricular septal defect. However, the mitral valve was found to be normal after the excision of the ring. The ring has been attaching itself to the mitral valve, so it required a meticulous surgical technique to avoid injury to the mitral valve itself.
