Analysis of echocardiographic missed diagnosis and misdiagosis of infants with coarctation of the aorta / 中华超声影像学杂志

ABSTRACT

Objective To explore the clinical value of two dimensional and color Doppler echocardiography in diagnosis of infants with coarctation of the aorta(CoA),and to analyse the cause of missed diagnosis and misdiagnosis.Methods The echocardiographic characteristics of 87 infants with CoA were analyzed retrospectively,and the results were compared with surgical findings.Results Seventy-five patients were correctly diagnosed,while 9 patients were missed and 3 patients were misdiagnosed.Discrete coarctation was found in 67 cases,whereas tubular coarctation was detected in 8 cases of CoA.Conclusions Mastering the echocardiographic characteristics of infants with CoA and carefully scanning the sternum nest section,combined with two dimensional and color Doppler echocardiography,could avoid missed diagnosis and misdiagnosis.
