Case 4/2013 - Woman with Transposition of the Great Arteries and Delayed Corrective Progress

DOI: 10.5935/abc.20130156 Clinical Data: After surgical correction of the transposition of the great arteries associated with other defects and heart failure, beginning with termino-terminal coartectomy and pulmonary artery banding at three months (weight = 3800 g) and use of the Jatene technique with the closing off of interventricular communication, and pulmonary banding at ten months (weight = 5200 g), the patient progressed well, recovering weight and remaining symptom-free, despite the appearance of pulmonary artery stenosis at five years of age, improved after dilation by balloon catheter and resulting in a reduction in the pressure gradient, down from 72 mmHg to 26 mmHg. Since then, she has been taking 40 mg/day of propranolol for slight but persistent stenosis of the right ventricular outflow tract. She currently tolerates routine exercises well and does not mention symptoms.
