CLASSIFICATION OF VENTRICULAR SEPTAL DEFECTS (VSDS) ON THE BASIS OF GENETICS
Ventricular Septal Defects (VSDs) account for 30% to 60% of all congenital heart diseases in neonates. VSDs are one of the commonest abnormalities, affecting human heart and has been the focus of interest in several studies since years. Strong evidence regarding the involvement of genes in causing VSDs has been accumulated over the years. The classification based on genetics, including three types of VSDs; VSD1, VSD2 and VSD3, is the focus of this paper.
