Interventricular septal defects resulting from nonpenetrating trauma are rarely diagnosed antemortem. In 1952, Pollock et al.7 reviewed the literature and found 12 cases to which they added 1 autopsied case of isolated rupture of the healthy interventricular septum. Recently, Cary and Hurst 2 reported one additional case diagnosed at autopsy. The first recorded case established by cardiac catheterization was reported by Guilfoil3 in 1953. We have not found any other catheter-proven cases resulting from nonpenetrating injury. Two surviving cases are presented.
