Impact of Cardiac Surgery Scar on Heart Rupture Following a Fall from Height

Death from falls accounts for a significant number of injuries and fatalities globally, often linked to suicides, workplace accidents, or substance abuse, and rarely to homicidal causes. Injuries from falls vary based on height, impact point, and surface struck, with severe trauma often seen, including visceral ruptures, organ lacerations, and complex fractures. Even minimal external injuries can mask severe internal damage, such as multiple organ ruptures, organ tears, and large vessel lacerations. Blunt cardiac injuries, which occur in 5% to 50% of falls, are significant, especially in falls over 6 m. In 70% of the cases, cardiac rupture is observed at the level of the posterior wall of the heart and occurs due to a contusive action on the heart during the diastolic filling phase. We report a case of a 29-year-old man (weight 95 kg) who died from an 11-meter fall. He had a history of cardiac surgery for the transposition of the great vessels, and an autopsy revealed extensive cardiac rupture, likely worsened by fibrotic adhesions anchoring the heart to the pericardium. Toxicological investigations on peripheral blood showed BAC > 2.58 g/L. Heart scars, macro- and microscopically as a deposit of fibrous tissue, due to previous surgery, may have contributed to the extent of the lesion, suggesting the need for further study on post-operative tissue changes and their effects on trauma from falls.
