Aim: To evaluate the incidence of major congenital heart defects (CHD) in the Moravian-Silesian (MS) Region in a long-term prospective study. To describe the system of prenatal care and its effectiveness concerning detection of individual types of defects.

Methods: Ultrasound examination of the fetal heart (fetal echocardiography) carried out as a part of prenatal screening, mostly in the 2nd trimester of pregnancy. If a heart defect is suspected, general examination of the fetus and the pregnancy follows. The study is based on its authors' own series supplemented by data from regional pediatric cardiology clinics and from regional gynecologists-obstetricians. Another supplement is formed by pathological findings in fetuses with the assessment of associations between heart pathologies and genetic or extracardial disorders.

Results: Between 1999 and 2010, 506 major CHD diagnosed prenatally and/or postnatally occurred in the MS Region. The heart defect was typically identified as an isolated affection. The incidence of major CHD in our series is 3.55 per 1000 live births. Chromosomal aberration was diagnosed in 1.5% CHD. Down syndrome was the most common chromosomal defect. Sixty-four percent of major CHD are now being diagnosed prenatally in the given region. Fifty-five percent of parents decided to terminate the pregnancy in cases of prenatally identified CHD.

Conclusions: The system of prenatal care in the MS Region is gradually improving, the effectiveness of prenatal CHD detection increases, pathological pregnancies are being managed correctly, and the location of delivery is planned according to the severity of the CHD.
