　　Part of David's heart muscle grew thick and stiff, keeping the flow of blood．The disease David had lived with for 17 years was slowly strangling(抑制)his heart．

　　The doctor explained that the traditional treatment was open－heart surgery(＝operation)．

　　That night Flora bent forward in front of her computer; everybody else was asleep．For the prize, or keeping her husband alive?To do that, she needed to search for the data(资料)：a place and someone to fix David's damaged heart．And she needed to be lucky．

　　Finally, she found them on a magazine's website(网址)．She began printing articles．When David came into the study early in the following morning, she said,“I've found it,”and handed him the papers．

　　David wondered if there was any other way．then he thought about his wife and kids．He stared at the papers．Only he could make the choice：should he have the same surgery that had killed his father, or the one that no one was sure works?This experimental treatment might be his best hope．

　　The operating theatre was kept freezing cold．David was not frightened, just nervous．He felt a burning pain, like a burning knife cutting through his heart…

　　On the EKG screen, the tiny valley in the middle of each peak(＝pointed top of a mountain)－David's disease－smoothed out．For the first time in years, he had a normal arterial pressure．“That's the most unusual thing,”said Flora, excited by the result．

　　Three days later, David and Flora drove home after the flight from Houston．Their kids ran out to meet them．
