Abstract

Congenital heart defect is one of the most common birth defects. The isolated ventricular septal defect (VSD) has higher morbidity, and spontaneous closure may occur. Previously many studies about the prognosis of ventricular septal defect in childhood were conducted; in contrast, few studies on evolution and prognosis of ventricular septal defect from fetus to postnatal life have been available. This research aimed to determine the evolution of isolated ventricular septal defect during the period of fetus and postnatal life, and analyze the association between the diameter or location of VSD and the spontaneous closure of VSD. All pregnant women seen at the prenatal diagnosis center of the West China Second Hospital were recruited. From June 2011 to June 2014, these participants underwent the fetal 2-dimensional and color Doppler echocardiographic examinations, and the fetuses with isolated VSD were included in the study, and those with other malformations or abnormal chromosome were excluded. This study was a prospective and longitudinal research. These fetuses were followed-up until the VSD closed spontaneously, or were surgically repaired or percutaneously closed. Outcomes of all the cases were recorded. There were 234 fetu...Continue Reading

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.
