Teen survives nail gun to the heart

An Argentinean carpenter who had a three-inch nail accidentally shot into his heart has become one of the few people to survive such an injury.

The unnamed 19-year-old was shot by a colleague wielding a nail gun while working in a wooden pallet factory in Canuelas, Buenos Aires.

The man was taken to El Cruce Nestor Kirchner Hospital after the accident last Monday.

An X-ray revealed the nail had pierced straight through his heart muscle to become lodged in one of its chambers.

Surgeons could not simply pull out the nail because it was "acting as a stopper and preventing a hemorrhage," Medina said.

Instead, the man's breast bone was carefully opened up to allow the surgeons to see and gently remove the nail.
