Recommendations for Fetal Echocardiography in Twin Pregnancy in 2016

First trimester fetal karyotyping in twin pregnancy.

Fetal chromosome analysis in a twin pregnancy during the first trimester is described. Problems of the reliability of tissue sampling are also discussed. The authors emphasise the advantage of direct cytogenetic analysis from the tissue specimens used for enzyme determination or DNA studies.

Fetal Hydrops in a Twin Pregnancy

Hydrops fetalis is a well known condition with an extensive list of differential diagnoses. The etiology is divided into immunerelated and nonimmune-related types, and currently almost 90% of cases are associated with the latter category [1]. Among the various nonimmune-related causes, one of the most common are cardiac aberrations [2]. Prenatal ultrasound serves as the initial diagnostic tool ...

Doppler velocimetry for predicting fetal death in a twin pregnancy.

Separation of Abdominal Fetal Electrocardiograms in Twin Pregnancy

A combined application of independent component analysis and projective filtering of the time-aligned ECG beats is proposed to solve the problem of fetal ECG extraction from multi-channel maternal abdominal electric signals. The developed method is employed to process the four-channel abdominal signals recorded during twin pregnancy. The signals are complicated mixtures of the maternal ECG, the...

Fetal behavior and heart rate in twin pregnancy: a review.

Fetal movements and fetal heart rate (FHR) are well-established markers of fetal well-being and maturation of the fetal central nervous system. The purpose of this paper is to review and discuss the available knowledge on fetal movements and heart rate patterns in twin pregnancies. There is some evidence for an association or similarity in fetal movement incidences or FHR patterns between both ...
