We describe a case of congenitally corrected transposition of the great arteries (cc-TGA) successfully performed by the double switch operation after two-staged pulmonary artery banding (PAB). An eleven-year old boy diagnosed with cc-TGA underwent the first PAB at that age, followed by the second PAB one year later. Because of severe ventricular dysfunction and arrhythmia of the anatomic left ventricle, the intension of one-stage PAB was abandoned. Cardiac catheterization data from after the adequate second PAB provided the surgical indication for the anatomical correction and double switch operation (Senning+Jatene procedure) and this was successfully performed at age 14. Although cardioversion was required to treat supraventricular tachycardia in the early period after surgery, the patient was discharged from hospital and remains in good clinical condition at the last follow-up at 5 years with normal sinus rhythm and good biventricular function.
