““In Detroit, Dr. Forest Dodrill, a surgeon at Wayne State University, collaborated with engineers at General Motors Research to develop a mechanical pump capable of supporting the circulation of an adult. The resulting stainless-steel and glass device, the Dodrill-GMR mechanical heart pump, had multiple cylinders from which blood circulated and, perhaps not surprisingly, bore an uncanny resemblance to a Cadillac V-12 automobile engine. The device was intended to temporarily replace either the right or left ventricle and was first used in 1952 to support a patient for fifty minutes while Dr. Dodrill repaired a mitral valve.””
