0.37).Meanwhile a good correlation (Y=0.99X-0.18,r=0.987) was obtained. Though Westergren method correlated preferably with MICROTEST 1 (Y=0.86X+1.27,r=0.906),there was a markedly different (t=3.174,P=0.001).At last different references values were collected, according to sex and age.Male,32.5 mm/1 h(60 years old);Female, 34.03 mm/1 h(50 years old).Conclusions MICROTEST 1 correlated preferably with Westergren method.The examination by MICROTEST 1 needs small quantity of sample and fewer time.Furthermore,it has good repeatability and stability.The factors such as temperature and Hct have little influence on the results.The result suggested that it is suitable to apply MICROTEST 1 to large- scale clinical laboratory or other labs.But the reference value of ESR was influenced by age,which should be considered in clinical usage.

OBJECTIVETo observe the effects of transcatheter closure method for treating congenital coronary artery fistula (CAF) in children.

METHODSTwenty-three children with CAF received transcatheter closure. Under anesthesia, heart catheterization and selective coronary angiography were performed to show the CAF size and relationship with normal coronary artery. CAF with the narrowest inner diameter < 3 mm (n = 16) were occluded with coil device, and CAF with narrowest inner diameter > 3 mm (n = 7) were closed with Amplatzer duct or VSD occluder.

RESULTSTranscatheter closure was successfully performed in 21 cases and failed in 2 cases (CAF is too tortuous in one case and right CAF outlet near the right coronary artery main stem in another case) and CAF were closed by surgery in these 2 patients. No residual shunt or other complications were observed during the 3 months to 3 years follow up.

CONCLUSIONTranscatheter closure was an effective and mini-traumatic method for CAF treatment in children.
