Heart With No Beat Offers Hope Of New Lease On Life

Posted June 15, 2011 10:37 AM

From NPR:

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.

Great story, and I'm sure the guy who had that first one would have been proud to have been chosen... sad his time was limited anyway, but hats off to him, he sounds like one of us.

I've been thinking of this for a while now, and I'm not convinced that going 'beatless' will is obviously a good idea. On the one hand, it would have the advantage of being easier on the circulatory plumbing (no pressure pulses). On the other hand, pulsing may be the equivalent of exercise for said plumbing, so going with constant pressure may cause it to weaken as any 'muscle' would.

Other considerations: what would be the interplay between the circulatory system's pressure-management system (the plumbing's contracting and distending section by section), etc.?

Research is needed to discover what the effects of constant (adjustable) pressure are.
