1 Assessing the atrial septum Fig 1Assessing the atrial septum(secundum defect)Ho et al, Mosby-Wolfe 1995
2 Fig 2Secundum ASDApical four chamber view demonstrating a large secundum atrial septal defectSubcostal four chamber view of same patientconfirming a left to right shunt at atrial level
3 Fig 3Secundum ASD3D image of secundum ASD and image during transcatheter occlusion
4 TOE secundum ASD Fig 4 Transesophageal longitudinal view of the atria LARATransesophageal longitudinal view of the atriademonstrating an ostium secundum defect.Colour flow image from the same view demonstratingleft-to-right shunting across the ASD
5 Primum ASD Fig 5 Apical four chamber view demonstrating LVRVRALAApical four chamber view demonstratinga primum atrial septal defectColour Doppler flow image from same viewillustrating left-to-right shunt across the primumatrial septal defect
6 Fig 6Parasternal short axis view demonstratingtri-leaflet left atrioventricular valve in a patientwith a primum atrium septal defect
7 Primum ASD Fig 7 Subcostal four chamber view LA demonstrate an large primum atrialseptal defect which is located at the lowpart of normal atrial septum and thejunction with atrioventricular valve.RALVRV
8 Primum ASD repaired Fig 8 LV LA Apical four chamber view of patient with aprimum ASD repair. Note the thickenedleft AV valve leaflet and markedly dilatedleft atriumColour Doppler flow mapping of the samepatient demonstrating severe left AV valveregurgitation.
