Ventricular septal defect (subaortic) seen from parasternal long axis view Parasternal long axis view showing aorta (Ao), left atrium (LA), left ventricle (LV) and a small perimembranous (subaortic) ventricular septal defect. Mitral valve is in the open position and the aortic valve in the closed position. VSD Jet visualised by colour flow mapping (colour Doppler) [...]

The various positions of ventricular septal defects in double outlet right ventricle are: Subaortic VSD. Subpulmonary VSD, above the septal limb of the crista supraventricularis – Taussig Bing complex. Doubly committed VSD: VSD is very large and related to both semilunar valves. Remote VSD: AV canal or muscular type of VSD. No VSD (only outlet [...]

Parasternal long axis (PLAX) view in Tetralogy of Fallot, diastolic frame showing the aortic valve in closed position and mitral valve in open position. The aortic valve appears to impinge on the ventricular septum, but the ventricular septal defect (VSD) with aortic over-ride and connection between right ventricle (RV) and aorta (Ao) is evident just [...]

Apical five chamber view in Tetralogy of Fallot demonstrating the sub aortic ventricular septal defect (VSD) with aortic over-ride. 50% of the aorta (Ao) is committed to the left ventricle (LV) while the remaining half is committed to the right ventricle (RV). LA: left atrium; RA: right atrium. The VSD in Tetralogy of Fallot is [...]

Medium sized ventricular septal defect in peri-membranous location seen from the apical five chamber view. RV: right ventricle; LV: left ventricle; VSD: ventricular septal defect; Ao: aorta; RA: right atrium; LA: left atrium; IVS: interventricular septum. There is aneurysm of the inteverventricular septum covering the VSD, leaving a small gap. The VSD jet passes through [...]
