As per Dr Sreekanth Raghavan
Hi there,VSD means ventricular septal defect, it is a defect in the wall between the two chambers of the heart, which pumped the blood. This is a birth defect, and it is something that will be present at birth, and there is at present, no medicine that you can take during pregnancy that can correct this. But do not get very anxious as most heart defects are correctable after birth with the help of pediatric cardiologist and care. Just make sure you deliver in a center equipped with good neonatology facilities and make the neonatologist aware of this condition and advise his presence at birth. Around 1% of all babies are born with heart defects and most of them are correctable. You will 4 weekly ultrasound and fetal 2D echo during pregnancy to know the size and progress of the VSD. Hope this helps. Regards.
