The device can keep a heart warm and  beating�and viable for many hours longer than the conventional method  for handling donor hearts: immersion in a saline solution and packing in  ice.<img src="http://i34.tinypic.com/nmhky8.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Dramatic advances in computed tomography now provide detailed scans in  ten scalpel-free seconds. This image of a heart beating in a human chest  reveals a narrowed artery�potential trouble. <img src="http://i36.tinypic.com/w74fa.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Danuel Allen lived 54 days with an artificial heart implanted in his  chest. He was comforted by the thump, says Sharon, his wife, who could  hear the heart beating from across the room. A couple of weeks after  this photo was taken Allen received a transplanted human heart, but he  died from an infection within months<img src="http://i38.tinypic.com/1y6emu.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />More than 60,000 miles (97,000 kilometers) of arteries, veins, and  capillaries in an adult body pulsate to a muscular rhythm�100,000  heartbeats a day. Scientists once viewed the cardiovascular system as a  pump and a lot of pipes; now they increasingly focus                                                                  <img src="http://i34.tinypic.com/20hn3tk.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Holding a photograph of their parents, six Steffensen children�JoAnn,  Marvin, Jeanette, Betty, Donald, and Cecil�once confronted a disturbing  question: Why have members of their family suffered from an unusually  high rate of heart disease for generations? A few years ago, DNA tests  revealed that stricken family members share a mutant gene called MEF2A,  which produces a protein that appears to make arterial walls more likely  to rupture.                                                                  <img src="http://i35.tinypic.com/orno86.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />This polyurethane heart can keep critically ill cardiac patients alive  while they await a donated human heart. Once the device is surgically  implanted, its attached plastic tubes run through the patient's skin to a  battery-powered pneumatic pump. Despite the cost�$106,000� the demand  is strong. Some 3,000 people await heart transplants in the U.S., but  only about 2,100 donor hearts are available each year. While boosting  the supply of artificial hearts is a relatively simple technical hurdle,  increasing the supply of human hearts is more challenging. Who will be  tomorrow's donors? That question lingers for a patient in Germany, who  recently received a CardioWest artificial heart like this one.<img src="http://i38.tinypic.com/ezpj14.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />At the Berlin Heart Institute in Germany, 62-year-old Siegfried Streiter  endures four hours of surgery�from first incision to final sutures and  bandages�to get his artificial heart. The device will not only keep him  alive, says Dr. Roland Hetzer, chief surgeon; its strong, steady pulse  might also help clear the chronic congestion in his lung vessels. "A  transplanted human heart would have failed immediately, " says Hetzer. <img src="http://i38.tinypic.com/jj3a6o.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />     <img src="http://i34.tinypic.com/144328o.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Days after open-heart surgery, Lawrence Silberman tries to relax as  massage therapist Kathleen Ullmann administers craniosacral therapy.  With her gentle touch and extraordinarily sensitive fingertips, Ullmann  promotes a state of deep relaxation and facilitates the flow of fluids  that surround the brain and spinal cord, which can improve the  functioning of the central nervous system. Meditation and yoga also help  cardiac patients recover from surgery.         add comments & repz!!!!!!!!!!!</blockquote>
