Flowers and get-well wishes from fans around the world deluged the hospital where Lucille Ball was in critical condition Thursday recuperating from emergency heart surgery.

Ball's husband, Gary Morton, said the TV actress was "in great spirits."Doctors replaced the 77-year-old comedian's main heart artery, or aorta, and aortic valve Tuesday with organ tissue taken from the body of an unidentified 27-year-old man. Her condition was listed as critical, primarily because of the seriousness of the surgery, said Ron Wise, spokesman at Cedars-Sinai Medical Center.

"She continues to show steady prog-ress," Wise said late Wednesday. Doctors were optimistic Ball would make a full recovery, he added.

The hospital received hundreds of messages and inquiries from fans and the media worldwide, Wise said.

"Before it's over the hospital will look like a combination of the U.S. post office and the botanical gardens," he said.
