RESUMO
Objective To study the results of intraventricular tunnel procedure for double outlet right ventricle(DORV) with subaortic ventricular septal defect(VSD).Methods Nine children with DORV complicated with subaortic VSD underwent intraventricular tunnel procedure.Five of them had stenosis of pulmonary valve or subpulmonary stenosis,and one had double-chambered right ventricle. An intraventricular tunnel procedure was performed under cardiopulmonary bypass. Right ventriculotomy was made to repair the VSD with teflon patch. An internal tunnel was made between the left ventricle and the aorta.The right ventricle connected with the main pulmonary artery. Results All children survived and recovered finally. Echocardiography showed that the internal tunnel function was well.Conclusion With correct diagnosis and selection of procedure, intraventricular tunnel procedure is a satisfactory method for the treatment of DORV with subaortic VSD.
