Impact of low body weight on frequency of pediatric cardiac catheterization complications

The overall risk of pediatric cardiac catheterization remains low despite t he enormous new complexity and potential for complications brought on by th e growth of interventional catheterization techniques. For all patients age d <21 years, balloon interventions carry the highest risk, diagnostic proce dures carry more risk than non-balloon interventions, and although weight < less than or equal to>5 kg is a significant risk factor for complications, irrespective of the type of procedure performed, weight less than or equal to2.5 kg did not alter that risk.
