According to a recent paper published in Circulation, children’s risk for sudden death should be evaluated using different risk factors than those used for adults.

Two main differences seen between factors influencing the risk of sudden death of children and adults were that:

• for children, family history of sudden death was not a risk factor;
• a left ventricular outflow tract gradient in a child suggested a lower risk of sudden death.

The authors of this study propose that the risk assessment factors highlighted in this study (and not the various risk assessment tools that have been developed for adults) should be used by clinicians to evaluate the need for implantable defibrillators in children.
