Congenital heart defects in chick embryos subjected to temperature variations.
• Several epidemiological studies" have shown a positive correlation between viral diseases early in pregnancy and congenital heart disease in human beings. Since viral diseases are accompanied commonly by fever, it was considered important to investigate the effect of high temperature alone on the development of the heart in chick embryos. It was also thought that incubation at low temperature...
متن کاملAmbient temperature and congenital heart defects.
STUDY QUESTION Does maternal exposure during pregnancy to higher ambient temperature increase the risk of congenital heart defects (CHDs)? SUMMARY ANSWER Significant associations were found between maternal exposure during pregnancy to higher ambient temperature and CHDs risk especially during the cold season. WHAT IS KNOWN ALREADY From rodents to non-human primates, a teratogenic effect of...
متن کاملCongenital heart defects in adulthood.
BACKGROUND More than 90% of children with congenital heart defects now survive into adulthood; just a few decades ago, survival was rare, particularly among patients with complex defects. The new population of adults with congenital heart disease presents a special challenge to physicians from all of the involved specialties. METHODS Selective literature review. RESULTS AND CONCLUSION A com...

Background—This study determines the prevalence of Congenital Heart Defects (CHD), diagnosed prenatally or in infancy, and fetal and perinatal mortality associated with CHD in Europe. Methods and Results—Data were extracted from the European Surveillance of Congenital Anomalies central database for 29 population-based congenital anomaly registries in 16 European countries covering 3.3 million b...
متن کاملHemodynamic changes in chick embryos precede heart defects after cardiac neural crest ablation.
Neural crest cells are known to contribute to the normal architecture of the heart and aortic arch arteries. Ablation of neural crest cells over somites 1 to 3 in the chick embryo prevents conotruncal septation and results in persistent truncus arteriosus. To determine whether a deficiency of cardiac neural crest cells produces hemodynamic changes prior to the development of identifiable struct...
