Abstract
- Pulmonary venous wedge angiogram(PVWA) was performed in 23 patients with cyanotic congential heart disease dueto decreased pulmonary blood flow, as the part of whole of pulmonary arterial system had not been opacified by conventional angiogram. The pulmonary venous wedge angiogram visualized pulmonary arteries (1) with completely closed feeder or with severe peripheral stenosis in 16 patients with pulmonary atresia or TOF, (2) with the interruption of one pulmonary artery in 3 patients, and (3) in 4 patients with tight pulmonary stenosis where pulmonary arteries were not adequately delineated. PVWA has completed the map of entire pulmonary arterial system,which was essential in the surgical management of these patients.
