The Artificial Heart

The Artificial Heart [Re-blogged from #usagov]

The human heart beats around 2.5 billion times in an average lifespan. Each day, it pumps over 2,000 gallons of blood, providing each cell in the body with fresh oxygen - without which, we cannot survive. It seems like without a heart beating in our chest, we would be toast, right? Not so fast…

Dr. David Lederman, who founded Abiomed, Inc. a year after his father died of a heart attack, didn’t quite see it that way. “There is no reason a person should die when their heart stops,” Lederman said in a 2003 interview with CBS News. “If the person’s brain and the rest of his body is in good shape, why should people die?”

With that in mind, Lederman and Abiomed, Inc. created the AbioCor, a grapefruit-sized, plastic-and-titanium artificial heart. Robert Tools became the first human recipient of a self-contained artificial heart on July 2, 2001. The company deemed it would be considered a success if Tools survived for 60 days following the procedure. He survived for 151. Before his death, his artificial heart had beat over 20 million times inside Tools.

AbioCor was named Time Magazine’s Invention of the Year for 2001 (#1 in Health category), “for saving the life of Robert Tools and changing our perception of what is possible.”

Unlike the world’s first artificial heart, the Jarvik-7, developed in the 1980s by Dr. Robert Jarvik and its modern version,the SynCardia CardioWest, the AbioCor is self-contained, meaning it isn’t connected to external machines. And unlike its predecessors, which were created as a temporary solution for patients waiting for a human heart transplant, the AbioCor is a permanent  replacement.

Though many developments have been made in the 12 years since AbioCor’s creation, it can be traced back as the spawn of these new devices, responsible for redefining perceptions of life, and allowing humans to survive without a living heart.

Le virus zika poursuit sa progression

Le virus zika continue de se répandre en Amérique latine et centrale, notamment au Salvador où les autorités recommandent aux femmes enceintes de reporter de deux ans leurs projets de grossesse, le virus, transmis par des moustiques, étant responsable de nombreux cas de microcéphalie chez les nouveau-nés.

Préoccupé par le phénomène, qui touche aussi les Caraïbes, Washington appelle les femmes enceintes à éviter une vingtaine de pays. “Nous sommes relativement inquiets des complications potentielles pour le foetus en cas d’infection au virus Zika, donc nous recommandons aux femmes enceintes de repousser, si possible, leurs voyages dans les zones à risques”, explique le Docteur Beth Bell des Centres de contrôle et de prévention des maladies (CDC)

C’est au Brésil que le zika fait le plus de ravages. Les autorités ont enregistré en l’espace d’un an quelque 4.000 cas de malformations du crâne chez les nouveau-nés et une cinquantaine de décès. Pour endiguer la propagation du virus, les hôpitaux ont commencé à utiliser un test capable de dépister en quelques minutes le zika, ainsi que la dengue et le chikungunya, tous transmis par le même insecte, ‘‘le moustique tigre’‘. Fièvre, maux de tête, courbatures, éruptions cutanées sont les principaux symptômes du virus. Ils se manifestent dans les trois à douze jours.
