Insights
A complex pediatric heart condition involving double-outlet right ventricle and pulmonary artery stenosis was treated using novel surgical techniques. The successful intervention involved VSD closure and pulmonary artery plasty, offering hope for similar challenging cases.
Area of Science:
- Pediatric Cardiac Surgery
- Congenital Heart Disease
- Surgical Techniques
Background:
- A 14-year-old female presented with a history of Jatene operation for double-outlet right ventricle and multiple muscular ventricular septal defects (VSD).
- Follow-up revealed bilateral pulmonary artery stenosis and persistent multiple muscular VSDs, with significant right ventricular pressure elevation.
Observation:
- Echocardiography and cardiac catheterization confirmed severe pulmonary artery stenosis and elevated right ventricular pressure (93% of left ventricle).
- Previous attempts at balloon angioplasty for pulmonary artery stenosis were unsuccessful.
Findings:
- The patient underwent successful surgical repair utilizing a sandwich technique for VSD closure.
- Pulmonary artery plasty combined with superior vena cava translocation was performed to address the stenosis.
Implications:
- This case highlights the successful application of advanced surgical techniques for complex congenital heart defects.
- The described operative approach offers a potential solution for managing challenging cases of double-outlet right ventricle with pulmonary artery stenosis and VSDs.
Abstract:
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.
