Tetralogy means 'four', hence there are four main things wrong with the heart: Sub-pulmonary stenosis: A narrowing below the pulmonary valve Ventricular Septal Defect: A hole in the wall between the ventricles which means that blood can leak from one side to the other Over-riding aorta: The entrance to the aorta, which should only carry oxygenated blood, lies over the VSD allowing the right ventricle to pump some deoxygenated blood directly into it Thick right ventricle: The right ventricle...

Cooper’s Heart Aug 26, 2008
Cooper is 18 months old and born with this heart defect which causes him to suffer from supraventricular tachycardia (SVT) ... This electrical activity is initiated in the sinoatrial (SA) node in the right atrium of the heart, then passes through the gatekeeper , the atrioventricular (AV) node, to then the bundle of His ... In severe cases, extreme cardiac instability can trigger ventricular fibrillation - uncoordinated contractions of the muscle in the lower chamber (ventricles). (Thomaston Times, GA)
Heart Disease Aug 24, 2008
But it also might result in ventricular fibrillation, in which the heart muscle begins fluttering instead of pumping. If the heart's normal pumping action isn't restored quickly, either through cardiopulmonary resuscitation (CPR) or the use of an electric defibrillator, death from cardiac arrest is likely.

Antimicrobial Sutures Reduce Infections In Brain Shunt Surgery, Study Finds Jul 29, 2008
ScienceDaily (July 28, 2008) Children born with hydrocephalus, or "water on the brain" must have shunts implanted to drain the fluid away from the brain to reduce harmful pressure. While shunts do their job well, the rate of shunt infection in children is very high for a variety of reasons, which requires putting the child through another surgery to replace the shunt, bringing with it more hospital time, potential additional neurological complications and an increased risk of death.
