Rupture of the left ventricle due to blunt trauma--a pediatric case study and literature review

Area of Science:

• Forensic Pathology
• Cardiovascular Trauma
• Pediatric Traumatology

Background:

• Cardiac tamponade from ventricular rupture is a rare consequence of blunt thoracic trauma.
• Previous literature primarily associates such injuries with high-impact events like motor vehicle accidents.
• Isolated cardiac rupture, especially in pediatric cases from household accidents, is exceptionally uncommon.

Observation:

• A five-year-old child sustained fatal blunt force trauma from falling concrete basins.
• Autopsy revealed extensive mediastinal hemorrhage, hemopericardium, and a massive rupture at the left ventricular apex.
• External examination showed no definitive signs of thoracic or abdominal trauma, complicating mechanism determination.

Findings:

• Pathological examination confirmed the traumatic etiology of the cardiac rupture.
• No underlying cardiac pathology was identified as a contributing factor.
• The rupture was attributed to blunt force trauma, likely from the household accident.

Implications:

• This case underscores the potential for severe, isolated cardiac injuries from seemingly low-energy household accidents.
• It highlights the importance of detailed accident reconstruction and background information in forensic investigations.
• The findings contribute to the sparse literature on pediatric cardiac rupture, emphasizing the need for awareness of unusual trauma mechanisms.
