Natural history of a ventriculoatrial fistula after a gunshot injury in 1945.

We describe an exceptional case of a patient who suffered a penetrating heart injury from a gunshot wound in 1945 leading to a left ventricular-right atrial fistula. Despite the resulting left-to-right shunt the patient remained relatively asymptomatic for 50 years before the onset of congestive heart failure necessitated an operation.
