A 16-year-old girl presented with dyspnea 15 years after the Mustard operation for transposition of the great arteries with intact ventricular septum. An echocardiogram revealed secondary pulmonary hypertension due to pulmonary venous obstruction. Cardiac catheterization showed the left (pulmonary) ventricular pressure was over the systemic level. We performed a successful one-stage switch conversion. The patient is doing well 1 year after the switch conversion.
