The search for the perfect artificial heart seems never-ending. After decades of trial and error, surgeons remain stymied in their quest for a machine that does not wear out, break down or cause clots and infections.
But Dr. Billy Cohn and Dr. Bud Frazier at the Texas Heart Institute say they have developed a machine that could avoid all that with simple whirling rotors — which means people may soon get a heart that has no beat.
The doctors say the continuous-flow pump should last longer than other artificial hearts and cause fewer problems. That's because each side has just one moving part: the constantly whirling rotor.
But I'm all for progress.
