Major Cardiovascular Abnormalities

--Mark Hill 13:28, 30 September 2009 (EST) Please avoid using acronyms in the image labeling. I would have liked all the images to have been uploaded as "Heart defect - full name of defect.jpg" as they are from UNSW Embryology and not figures that you have drawn. This would also look better as a gallery format.
