Closure of Multiple Ventricular Septal Defects by the Sandwich Technique and Pulmonary Artery Plasty after Arterial Switch Operation

A 14-year-old girl had undergone a Jatene operation for double-outlet right ventricle with multiple muscular ventricular septal defects (VSD) at 12-day-old. During follow up periods, she was diagnosed with bilateral pulmonary artery stenosis and multiple muscular VSDs by echocardiography. Cardiac catheterization revealed elevated right ventricular pressure up to 93% of left ventricle. Multiple times balloon angioplasty failed to improve pulmonary artery stenosis. She underwent closure of multiple VSDs by the sandwich technique and pulmonary artery plasty with translocation of superior vena cava. We present operative technique for the complicated lesions in these operation.
