Donor organs are scarce enough for adults with heart failure. For infants and young children, the prognosis can be even grimmer. Not only are fewer organs available, the hearts of the very young can fail suddenly, without the symptoms that older people usually exhibit. Although mechanical heart pumps are routinely used to help adolescents and adults buy some time, they're too big for small children.

Building an artificial heart seemed so easy in the 1960s: design a pump, implant the contraption in a patient's chest and hook it up to the arteries. How naive medical researchers were in that era of moon shots.

Jarvik was chairman and chief executive of the Salt Lake City-based firm that manufactures and markets the artificial hearts he designed. In a release, the company said: "The board sincerely appreciates his many contributions to the company and recognizes his outstanding scientific accomplishments. The board wishes to emphasize that Jarvik's termination did not result from the recent tender offer for the company's common shares." E. M. Warburg Pincus & Co.

In the first use of an artificial heart in California, a team of surgeons in San Diego has implanted a Jarvik-7 mechanical heart in an Escondido man whose transplanted human heart had failed. Randy Dunlap, 34, received the device at Sharp Memorial Hospital on Tuesday after his transplanted heart failed to support his circulation. Hospital officials said the device is to serve as a temporary "bridge" to keep Dunlap alive until another human heart can be found.

A biotechnology company is developing a permanent, implantable, battery-operated artificial heart, and it is hoped that the device will allow patients to lead more normal lives than earlier artificial hearts. The new heart is designed to give patients greater freedom than previous artificial hearts because it will be powered by an internal, rechargeable battery rather than attached to a bulky, external power source.

Bruno, a bouncy mutt whose back muscle was transformed into an experimental heart pump, has died after 2 1/2 months with the implant. The dog was part of a University of Pennsylvania research effort to find ways to help people with congestive heart failure. The dog died Jan. 28 after small blood clots apparently formed in the pump and traveled through arteries to his kidneys, said Dr. Larry Stephenson.

A "fired up" William Schroeder moved out of the hospital Sunday for the second time since his artificial heart implant and was driven to the specially equipped apartment where he hopes to stay until he can return to his Indiana home. "He just couldn't wait to get going," Schroeder's son, Stan, said after his father was taken to the apartment where he had lived for a month before suffering a second stroke last May. "He was just fired up and ready to go."

The Jarvik-7 artificial heart probably will never be a satisfactory permanent implant because the infections it causes are unavoidable, researchers concluded Thursday. Doctors familiar with the air-driven pump called for a 30-day limit on using the Jarvik as a bridge to a human heart transplant, and one physician warned that future attempts at permanent transplantation "will only serve to further document the magnitude of the complications." But Dr.

The Arizona surgeon who performed the controversial artificial heart transplant in Tucson last week said Wednesday he envisions cardiologists using the mechanical pump as a stopgap device while patients wait for donor hearts. Speaking to reporters in Anaheim, Dr. Jack G. Copeland said that 10 years ago cardiologists formed two "separate camps," one working on techniques for transplanting human hearts, the other developing artificial hearts. Now, he said, there is "increasing awareness . . .
