VATICAN CITY – The death of an Italian muscular dystrophy patient who had his respirator disconnected is fueling a complex and significant discussion among top church officials. Piergiorgio Welby, who was paralyzed and kept alive by a breathing machine for nine years, pleaded for months for the device to be turned off. He said medical technology was only artificially postponing his death. In late December, a physician granted his request, and Mr. Welby died shortly afterward.
