Accessory mitral valve tissue in combination with subaortic membrane and significant impairment of left ventricular function.
A 6-year-old girl was found to have a combination of accessory mitral valve tissue and subaortic membrane. The association caused left ventricular outflow tract obstruction leading to severe left ventricular dysfunction. Surgical relief of the obstruction resulted in immediate improvement of ventricular function.
