Value of transthoracic echocardiography and cardiac multi-slice spiral computed tomography in the diagnosis of partial anomalous pulmonary venous connection in children / 中华实用儿科临床杂志

ABSTRACT

Objective To make a comparison of transthoracic echocardiography (TTE) and cardiac multi-slice spiral computed tomography (MSCT) in the diagnosis of partial anomalous pulmonary venous connection (PAPVC) in children.Methods One hundred and one patients admitted from February 2008 to April 2014 in Guangdong General Hospital primarily diagnosed with PAPVC with or without other congenital heart diseases were analyzed retrospectively,all the cases underwent routine TTE,which 74 cases underwent cardiac MSCT examination,and the TEE and cardiac MSCT diagnosis results were compared with final surgical findings,then the TTE and cardiac MSCT diagnosis accuracy was calculated.SPSS 13.0 software was used to analyze the data.Results All the patients underwent TTE examination,meanwhile,74 cases received cardiac MSCT examination.Ninety-three cases were confirmed by surgical findings,while 8 cases were misdiagnosed with PAPVC.Sixty-eight cases diagnosed by TTE coincided with surgical findings,and the diagnosis accuracy was 73.12％ (68/93 cases);65 cases diagnosed by cardiac MSCT coincided with surgical findings,and the diagnosis accuracy was 94.20％ (65/69 cases).Among the patients who received both TTE and cardiac MSCT examinations,66 cases were confirmed through final surgical operation,2 cases were mis-diagnosis,so the diagnosis accuracy was 97.06％ (66/68 cases).Conclusions In terms of the diagnosis accuracy of PAPVC,cardial MSCT examination is superior to TTE,as almost all of the cases could be diagnosed by TTE combined with cardial MSCT.In consideration of the acoustics window of children,apart from the conventional parasternal approach of detecting pulmonary veins,the importance of suprasternal and subcostal views should also be attached.
