Yelena Bonner, wife of Soviet dissident Andrei D. Sakharov, will undergo a heart-bypass operation next week because less drastic treatments failed to correct her blocked arteries, doctors said in Boston. Dr. Adolph M. Hutter, a cardiologist at Massachusetts General Hospital, decided surgery was necessary after examining Bonner with Dr. W. Gerald Austen, chief of surgery, a hospital spokesman said. Bonner, 62, who received a 90-day exit visa to seek medical treatment in the West, will be admitted to the hospital Sunday, and the operation will be performed the next day. Her visa expires March 2.
