Abstract:
Objective Tetralogy of Fallo( TOF) is one of cyanotic congenital heart disease, which is difficultly diagonosed because of its complicated texture.The aim of this study was to evaluate the manifestation and value of echocardiography in diagnosis of TOF. Methods The fetal sonograms of 99 fetuses with prenatal diagnosis of TOF in 5791 gravida were reviewed and analyzed from January 2010 to December 2012. Results Ninty nine fetuses with TOF were all diagnosed accurately by prenatal ultrasonography, including 11 cases with pulmonary atresia, 2 cases with complete atrio-ventricular septal defect and 4 cases with permanent left superior vena cava.The key echocardiographic features of TOF were ventricular septal defect, overriding aorta and pulmonary stenosis.TOF was accurately diagnosed by prenatal echoeardiography combined with visualization of TOF in four chamber view, outflow tract view and three vessels view.Sixty eight fetuses were confirmed to be TOF by autopsy or operation after birth, 12 cases refused to autopsy and 19 cases lost of follow up in the total 99 cases.None of TOF was reported to us in other 5692 gravidas. Conclusion The echocardio-graphy has important clinic value in diagnosis of fetal TOF with high sensitivity and specificity.
