Here are some extracts from the cardiologist's report. Am reproducing here as I know many people who have been in similar situations, and who know more about this than I do, have expressed interest.

Foetal echocardiography gave quite good views of the heart. There does appear to be a moderate perimbraneous ventricular septal defect with some outlet septal malalignment producing mild aortic override. This defect appears single. The atrioventricular valves are normally off-set both measuring about 6 to 7mm with normal flow patterns although trivial tricuspid incompetence is present. The aorta arising from predominantly left ventricle measures about 6mm with normal appearing aortic valve. The aortic arch is good size without obvious obstruction. The pulmonary artery can be seen arising from the right ventricle with mild pulmonary valve stenosis, and a pulmonary artery measuring from about 5mm. The branch pulmonary arteries appear normal. I could not be confident about the presence or absence of the duct. Venous return to the atria appears normal.

Thus there appears to be a perimembraneous malaligned ventricular septal defect with some pulmonary stenosis present. This is relatively mild at this moment with good size pulmonary arteries. The foetal cardiac abnormality is unlikely to cause any sign of foetal cardiac compromise. Ventricular septal defects may decrease in size but also pulmonary stenosis may increase during the pregnancy and in the postnatal period.

At birth the cardiac abnormalities may cause symptoms or signs dependent upon the size of the ventricular septal defect and the severity of pulmonary stenosis. If there is little pulmonary stenosis then a moderate ventricular septal defect may produce signs of a significant left to right ventricular shunt. However if there is moderate or more extensive pulmonary stenosis, then the infant is likely to be well but will develop some signs of right to left shunting with time.
