Prenatal diagnosis and management of congenital heart defect: significance of associated fetal anomalies and prenatal chromosome studies

Abstract

A fetal cardiac defect was found prenatally by ultrasound in 13 of 230 women (5.6%) with a suspected fetal anomaly. Pregnancy duration varied between 17 and 39 weeks (mean 28 weeks). The reasons for referral of the 13 patients were: suspected fetal structural defect (n = 4), oligo- or polyhydramnios (n = 2), severe fetal growth retardation (n = 1), fetal cardiac arrhythmia (n = 1), or a combination thereof (n = 5). Abnormal chromosomes were found in 5 out of 13 fetuses (38%)-ie, four through prenatal and one through postnatal analysis. The present study demonstrates that fetal cardiac structural anomalies often are diagnosed in combination with ultrasonically established associated abnormality. Cytogenetic analysis of amniotic cells greatly improves diagnosis and obstetric management, especially when the cardiac defect per se is considered amenable to surgical treatment and other major structural defects have been ruled out.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Cardiac Conduction System

The cardiac conduction system is a specialized tract of myocardial cells responsible for maintaining normal cardiac rhythm. Discover the latest research on the cardiac conduction system here.

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.
