Abstract

Left ventricular-right atrial shunt is a relatively uncommon defect, which permits as communication between the left ventricle and right atrium. This paper is fifth case report in our country. This patient was noted to have congenital heart disease in two years old. The pathology of this lesion was classified into four types by Perry. The type C is compatible with this case. The first successful surgical correction was made by Kirby in 1957. The pathology of this lesion was classified into four types by Perry. The type C is compatible with this case. The first successful surgical correction was made by Kirby in 1957. In 12 years old boy, we have experienced a case of left ventricular-right atrial shunt. In selective left ventricular angiocardiography, we found opacification to right atrium and main pulmonary artery simultaneously, and also opacified right ventricle later. Operation was performed during cardiopulmonary bypass. We opened right atrium and found out a defect just below the annulus of the tricuspid valve. The defect measuring 6mm in diameter communicate the left ventricle with right atrium through a segment of the septal leaflet fused to the margins of the septal defect. In the tricuspid valve, a cleft, 4mm in length and a isolated perforation(2mm in diameter) were found in the septal leaflet. Associated cardiac anomaly was a non-functioning patent foramen ovale. The recovery was uneventful and discharged healthily on fourteenth day after operation.
