OBJECTIVES: To determine the prevalence and time course of @entity2294 after open heart surgery for congenital @entity299 and to identify predisposing risk factors. DESIGN AND @entity1 : Prospective assessment of development of @entity2294 in 336 @entity1 (163 males) undergoing open heart surgery for @entity299 by serial echocardiography on days 5, 7, 14, 21, and 28 postoperatively. SETTING: Tertiary paediatric cardiac centre. RESULTS: The prevalence of @entity2294 was 23% (77 of 336). Of the 77 @entity1 who developed effusion, 43 (56%) had moderate to large effusions and 18 (23%) were symptomatic. @entity1 who had a large amount of effusion were more likely to be symptomatic than those with only a small to moderate amount (47.4% v 15.5%, p = 0.01). The mean (SD) onset of @entity2294 was 11 (7) days after surgery, with 97% (75 of 77) of cases being diagnosed on or before day 28 after surgery. The prevalence of effusion after Fontan-type procedures (60%, 6 of 10) was significantly higher than that after other types of cardiac surgery: repair of left to right shunts (22.1%, 43 of 195), repair of lesions with right ventricular outflow tract obstruction (22.6%, 19 of 84), arterial switch operation (6.7%, 1 of 15), and miscellaneous procedures (25%, 8 of 32) (p = 0.037). Univariate analyses showed that female @entity1 (p = 0.009) and those receiving @entity1229 (p = 0.002) had increased risk of @entity2294 . A greater pericardial drain output in the first four hours after surgery also tended to be significant (p = 0.056). Multivariate logistic regression similarly identified @entity1229 treatment (beta = 1.73, p = 0.009) and female sex (beta for male = -0.63, p = 0.037) as significant determinants. CONCLUSIONS: @entity2294 occurs commonly after open heart surgery for @entity299 . Serial echocardiographic monitoring up to 28 days postoperatively is indicated in selected high risk @entity1 such as those with symptoms of @entity8198 and those given @entity1229 .
