In pediatric resuscitation, how does the presence of congenital heart disease influence the approach to ROSC?

• A. It has no impact on management.
• B. It requires ECMO/eCPR only after ROSC.
• C. It requires more diuresis.
• D. It may necessitate early consideration of ECMO/eCPR and tailored hemodynamic management.

Answer: (D)

The key idea is that congenital heart disease changes the way blood can be circulated and oxygenated after a cardiac arrest, so the plan to achieve and sustain ROSC must adapt to the patient’s unique anatomy. In many CHD cases, traditional chest compressions may not provide reliable systemic perfusion, and the balance between systemic and pulmonary blood flow can be extremely fragile. Because of this, early consideration of ECMO/eCPR can offer immediate circulatory and oxygenation support, buying time to stabilize the patient and address the underlying anatomy. Once ROSC is achieved, hemodynamic management must be tailored to the specific CHD physiology—adjusting preload, afterload, vascular resistance, and the use of inotropes or vasopressors to maintain adequate systemic perfusion and appropriate pulmonary blood flow. In short, the presence of CHD often calls for prompt ECMO/eCPR consideration and customized hemodynamic strategy rather than relying solely on standard resuscitation steps.
