[Right ventricular outflow tract reconstruction using a three-valved extracardiac conduit of expanded polytetrafluoroethylene vessel graft in the Ross operation: a pediatric case report].
A 16-year-old boy was diagnosed as having severe aortic regurgitation and moderate aortic stenosis due to congenital aortic bicuspid valve. A chest X-ray film showed the cardiothoracic ratio (CTR) of 64% and echocardiography revealed severe dilation of the left ventricular dimension with severe wall thickness. An electrocardiogram showed multiple ventricular arrhythmias. The patient underwent the Ross operation with the reconstruction between the right ventricle and the pulmonary arteries using a three-valved conduit which was made by an expanded polytetrafuloroethylene vessel graft. Ventricular arrhythmia disappeared just after the operation and left ventricular dimensions improved with the CTR of 53% except mild regurgitation of the neo-aortic valve three months later.
