Multiple ventricular septal rupture after blunt trauma.

Ventricular septal rupture occurring as a result of blunt trauma is a very rare clinical condition. Compression of the heart between the sternum and the vertebral column during late diastole or isovolumetric contraction resulting in sudden increase in the intracardiac pressure is a prerequisite for its occurrence. Sudden relief of the inner pressure becomes impossible when the heart is full, thereby resulting in myocardial contusion and rupture.
