Traumatic ventricular septal defect in a 4-year-old boy after blunt chest injury
Yun Mi Kim, Byung Won Yoo, Jae Young Choi, Jun Hee Sul, Young Hwan Park
Clin Exp Pediatr. 2011;54(2):86-89.   Published online February 28, 2011

Traumatic ventricular septal defect (VSD) resulting from blunt chest injury is a very rare event. The mechanisms of traumatic VSD have been of little concern to dateuntil now, but two dominant theories have been described. In one, the rupture occurs due to acute compression of the heart; in the other, it is due to myocardial infarction of the septum. The...
