Twenty @entity1 varying in age between 5 and 20 years at the time of surgical closure of @entity1757 were studied 2 to 9 years postoperatively. Ventricular function was studied by echocardiography and measurement of systolic time intervals for the left and right ventricles and the findings were related to clinical and haemodynamic results of operation. The @entity1757 was closed in all instances and the haemodynamic situation was normalized in all but 2 @entity1 who had persisting @entity358 . @entity714 ( @entity714 ) was recorded in 11 instances and in 5 there was an associated @entity2270 ( @entity2270 ), suggesting @entity1347 . @entity2270 occurred as an @entity154 in another 2 @entity1 . The heart size was within normal limits in all the @entity1 . @entity1757 ( @entity1757 ) was recorded in 13 of the 20 @entity1 , but other echocardiographic analyses, such as LV end-diastolic dimension, left atrial/aortic root ratio, posterior wall velocity index and maximal endocardial velocity, were all within predicted normal limits. There was an almost uniform prolongation of both left and right pre-ejection periods. left and right ejection period as a rule remained normal and gave an increased PEP/ET ratio, indicating the presence of postoperative @entity67 also in instances with complete normalization of the haemodynamic situation. Suggested background mechanisms for these findings are the frequent occurrence of conduction defects postoperatively, the likelihood of altered ventricular compliance and possibly also as a cause of @entity1757 postoperative presence of an opened pericardial sac.
