Abstract
A 3-year-old boy with double-chambered right ventricle (DCRV), ventricular septal defect (VSD) and pulmonary stenosis underwent successfully surgical correction without a right ventriculotomy. This surgical approach consisted of a combined right atriotomy and pulmonary arteriotomy. A perimenbranous VSD was closed through the tricuspid valve, and the anomalous muscle bands of right ventricular outflow obstruction were resected through both the tricuspid valve and pulmonary valve. The pressure gradient between the right ventricle and pulmonary artery decreased from 70mmHg to 20mmHg. No major complications occurred after the repair. The transatrial approach with pulmonary arteriotomy is an appropriate and effective method to correct a DCRV.
