Ruptured interventricular septum after blunt chest trauma: ultrasonographic diagnosis.

A 6-year-old child was found under a heavy bookcase that compressed her chest. On admission to the emergency room she was found to be dyspneic with a systolic murmur and complete atrioventricular (A-V) block. Her condition deteriorated rapidly, leading to cardiogenic shock and loss of consciousness. Echocardiographic Doppler evaluation demonstrated a large ventricular septal defect and tricuspid insufficiency. A pericardial patch was put over the tear in the septum, and torn chordae tendinae were reimplanted to the papillary muscles. A pacemaker was inserted. Her situation improved, but on the third day cardiogenic shock and right ventricular dysfunction ensued and the patient expired. A review of the previous 13 cases from the pediatric literature is presented.
