@entity4214 -201 myocardial imaging was performed in 21 @entity1 with @entity3886 ( @entity3886 ). Thirteen @entity1 were studied before operation, eight @entity1 after Mustard operation and five @entity1 after Rastelli operation. Five @entity1 were studied sequentially before and after the surgery. Each image was compared with hemodynamic and angiographic findings in order to assess the usefulness of this method. In the 13 @entity1 with preoperative @entity3886 , it was possible to differentiate @entity3886 with the intact ventricular septum from @entity3886 with associated anomalies such as @entity2461 or @entity1757 , and also @entity3886 with @entity120 or @entity849 from @entity3886 without them by evaluating the degree of @entity4214 uptake in the free wall of the pulmonary ventricle (anatomical left ventricle). The degree of @entity4214 uptake was well correlated with systolic pressure of the pulmonary ventricle (r = 0.98). In the 13 @entity1 with postoperative @entity3886 , it was less correlated with the pulmonary ventricular systolic pressure (r = 0.83). Four cases sequentially studied showed a marked decrease in @entity4214 uptake in the pulmonary ventricle 10 to 16 months after Rastelli operation. But the corrected @entity4214 uptake ( @entity4214 activity/ventricular systolic pressure) was more increased compared with the uptake of the systemic ventricle after the surgery. This was probably related to a decrease of the pressure load to the pulmonary ventricle following the surgery and to the fact that there should be some delay of a decrease of the ventricular mass. An increased lung uptake of @entity4214 was noted in the cases of @entity997 after Mustard operation, but the degree of regurgitation was not clearly correlated with the increase of @entity4214 uptake in the lung. In five cases after Rastelli operation, one @entity1 showed a high degree of @entity4214 uptake of the pulmonary ventricle (anatomical right ventricle), and the conduit valve @entity730 and severe @entity849 were confirmed by cardiac catheterization and angiography. Thus myocardial imaging provides a reliable mean for the qualitative and quantitative assessment of @entity3886 before and after operation.
