Prenatal alleviation of severe fetal aortic valve obstructions by percutaneous ultrasound-guided balloon valvuloplasty has been performed to improve the fate of affected fetuses. The purpose of this study was to analyze the current world experience of these procedures in human fetuses. Data from 12 human fetuses were available for analysis. The mean(More)
BACKGROUND Fetal atrioventricular (AV) block is an uncommon lesion with significant mortality. Because of the rarity of this disorder, the natural course, extensive evaluation of untreated fetuses, and late follow-up remain unclear. METHODS AND RESULTS Of the 116 consecutive cases of fetal AV block studied from 1988 to 2006, only 1 was terminated, and 75%(More)
The aim of this study was to evaluate the detection of fetal structural abnormalities by the 11-14 week scan. 2853 pregnant women were submitted to a routine ultrasound scan between the 11th and 14th week and the fetal skull, brain, spine, abdominal wall, limbs, stomach and bladder were examined. Following the scans the patients were examined in the second(More)
OBJECTIVE To evaluate the association between abnormal ductus venosus (DV) at 11-14 weeks' gestation and chromosomal abnormalities, structural defects and fetal outcome. METHODS DV flow-velocity waveform (DV-FVW) and nuchal translucency thickness (NT) were prospectively evaluated in 1217 singleton pregnancies. RESULTS The DV-FVW was abnormal in 84(More)
OBJECTIVES We sought to describe a new technique for tricuspid valve repair in Ebstein's anomaly and to report early echocardiographic results, as well as early and midterm clinical outcomes. METHODS From November 1993 through August 2005, 40 consecutive patients with Ebstein's anomaly (mean age, 16.8 +/- 12.3 years) underwent a new surgical repair(More)
OBJECTIVE To determine the accuracy and practicality of fetal echocardiography in the identification of structural and functional cardiac abnormalities prior to 16 weeks' gestation in fetuses with increased nuchal translucency thickness (NT). METHODS Between January 1996 and June 2002 early fetal echocardiography using the transvaginal route was performed(More)
Congenital heart disease (CHD) is the most common birth defect and the leading cause of mortality in the first year of life. In fetuses with a heart defect, chromosomal abnormalities are very frequent. Besides aneuploidy, 22q11.2 deletion is one of the most recognizable chromosomal abnormalities causing CHD. The frequency of this abnormality varies in(More)
We report on the ultrasound features and natural history of trisomy 10. At 12 weeks' gestation in a routine scan examination, the fetus presented with increased nuchal translucency thickness, mild skin oedema, bilateral pleural effusion, marked micrognathia, cardiomegaly, unilateral talipes and reversed A-wave in the ductus venosus blood flow. Karyotyping(More)
Fetal echocardiography has recently caused an impact on the treatment of congenital heart disease and in the field of therapeutic, cardiological intervention. The present study reports on a case of critical aortic stenosis, diagnosed in utero at 27 weeks' gestation, and in which balloon dilatation was attempted to improve the poor prognosis associated with(More)
OBJECTIVE To determine the diagnostic accuracy of echocardiography for indicating surgery without catheterization in patients with congenital heart disease through a prospective analysis and comparison of the echocardiographic diagnosis with the intraoperative findings, or invasive study, or both. METHODS From February 2000 to January 2001, 493 patients(More)
