LILY DALE - Last month, Sylvia Lileberg, known as "Syb"- was not feeling well. After checking with doctors, she was surprised to learn she needed heart surgery. Still, another unexpected development was in store. Instead of one scheduled bypass, there were four completed during surgery on Jan. 9, at the Hamot Hospital in Erie, Pa. These days, Syb is on the mend. She's already able to perform important tasks like tending her window-sill garden and caring for Toby the dog.
