A 40-year-old lawyer was in stable condition last night after receiving a life-saving heart transplant at the weekend. Relatives appealed for a donor after Wong Yiu-kwong was admitted to Grantham Hospital in a critical condition. Their prayers were answered last Saturday when a heart became available and the operation went ahead. A spokesman for Grantham Hospital said Mr Wong had been critically ill and that a heart transplant had been his only hope. Last Friday, Mr Wong's sister made a desperate appeal for help on Commercial Radio's phone-in programme Teacup in a Storm. Mr Wong was diagnosed with a heart problem two years ago, and his heavy workload as a lawyer had caused his condition to deteriorate. His sister told the radio station that although he was conscious, he was very weak and unless he received an immediate donation, he would not live long as complications had set in. Grantham Hospital said 20 people were on the waiting list for the life-saving procedure. In the first six months of this year, it performed seven heart transplants, compared to 10 for the whole of last year. Since 1992 when the first heart transplant was successfully performed at Grantham, 46 people have received new hearts. Of these 39 are still alive. The hospital also performed two heart-lung transplants, although one patient has since died. Grantham is the only hospital in Hong Kong that performs heart transplants.
