Subendocardial infarction in two young boys
Insights
Subendocardial infarction can be observed in children following cardiac arrest. Assisted ventilation allows these myocardial changes to become visible at autopsy, impacting resuscitation survivor care.
Area of Science:
- Cardiovascular Pathology
- Pediatric Critical Care
Background:
- Subendocardial infarction is a type of heart muscle damage.
- Cardiac arrest in children presents unique challenges in resuscitation and post-arrest care.
Observation:
- Two cases of subendocardial infarction were identified post-mortem in young boys.
- Both children experienced prolonged cardiac arrest and were supported with mechanical ventilation.
Findings:
- The myocardial damage (infarction) likely occurred during the cardiac arrest due to insufficient blood flow.
- Extended mechanical ventilation enabled the gross and microscopic changes of infarction to develop and be detected.
Implications:
- This finding highlights the potential for developing myocardial infarction in pediatric cardiac arrest survivors.
- Understanding this phenomenon is crucial for managing and assessing outcomes in children resuscitated from cardiac arrest.
Abstract:
Two cases of subendocardial infarction noted at autopsy in young boys are reported. Both patients were resuscitated and maintained on ventilation following significant periods of cardiac arrest. Presumably the infarct occurred at the time of arrest, secondary to inadequate myocardial perfusion, and became visible at autopsy because both children were maintained on assisted ventilation long enough for the gross and microscopical changes to develop. The significance of this phenomenon for survivors of successful post cardiac arrest resuscitation is discussed.
