The world’s longest surviving heart-lung transplant patient was in critical condition after operations to repair a blood vessel and stop internal bleeding, a hospital spokeswoman said in Scottsdale, Ariz. Mary Gohlke, who received the transplant in 1981, had tripped and fallen in her home earlier in the week and was admitted to Scottsdale Memorial Hospital on Thursday. She remains in critical condition. Gohlke, 50, who suffered cardiopulmonary hypertension, received the transplant at the Stanford Medical Center in Palo Alto. She is the world’s fourth heart-lung recipient, and was the first to have the operation since 1971. Previously, the longest surviving patient lived for 23 days.
