Arkady N. Shevchenko, 67, a high-ranking Soviet diplomat and top official of the United Nations whose defection to the United States 20 years ago provoked an international diplomatic sensation, died of a heart attack Feb. 28 at his home in Bethesda.

Mr. Shevchenko had been working as the U.N. undersecretary general for three years and was second in rank only to then-Secretary General Kurt Waldheim when he left his New York apartment and rode off in a sedan driven by agents of the Central Intelligence Agency one night in April 1978.

He was the highest-ranking Soviet diplomat ever to defect, and his announcement that he would not return to the Soviet Union was met by accusations from Moscow that he was being held in the United States against his will. At the CIA, which Mr. Shevchenko had been secretly working for since 1975, the defection of such a key official was a major victory in the agency's struggle with the Soviet KGB security and espionage service.

At 47, Mr. Shevchenko was considered one of the rising stars of the Soviet foreign service, a career diplomat, an expert on disarmament issues and a protege of Foreign Minister Andrei Gromyko, whom he had served as secretary in Moscow. Colleagues said he was a doctrinaire communist who projected the image of the standard Soviet bureaucrat. His defection came at a sensitive time, when the Carter administration was moving toward an agreement with the Soviets on a strategic arms accord.

A month after Mr. Shevchenko's defection, his wife, Leongina, was found dead in her Moscow apartment. Soviet doctors said she commited suicide by taking an overdose of sleeping pills.

Within six months, the former diplomat was considering six-figure book offers from U.S. publishers while enjoying a comfortable retirement, financed in part by stipends from the CIA.

In October 1978, an American woman, a self-described call girl named Judy Chavez, told NBC television about a Caribbean vacation with Mr. Shevchenko in which she said he had paid her $5,000 a month to have a "relationship." She later described the relationship in a memoir called "The Defector's Mistress."

Friends said that Mr. Shevchenko drank heavily at times during the months before and immediately after his defection but that he later stopped. In 1979, he married Elaine Jackson, a court stenographer and Washington real estate saleswoman, who edited his 1985 autobiography, "Breaking With Moscow," which became a bestseller.

By then, Mr. Shevchenko was a confirmed celebrity. He analyzed developments in the Kremlin for American television, wrote opinion and analysis articles in The Washington Post and other American newspapers, taught at the State Department's Foreign Service Institute and toured the lecture circuit, commanding fees of $10,000 to $12,000.

But his autobiography was the first public confirmation that he had been a CIA spy. He wrote that he first approached the agency in 1975 and was told to supply information as proof of his sincerity. He described providing detailed information about Soviet intentions in Africa and Central America and about Politburo debates over China policy. He said his CIA handlers proved insensitive to the trauma of defection. About internal Soviet politics, he said, "Machiavelli would have been a student, not a professor."

The book was criticized in The Washington Post, which quoted publishing sources as saying certain scenes might have been "juiced up" for commercial purposes and CIA sources as saying Mr. Shevchenko's information was of limited value. In the New Republic magazine, author Edward Jay Epstein called the book a fraud. "What is fabricated here are not just car chases, meetings, conversations, reports, dates, motives and espionage activities, but a spy who never was," Epstein wrote.

Defending the book's authenticity was the CIA. "Arkady Shevchenko provided invaluable intelligence to the United States government," the agency said in a formal statement. "CIA had nothing to do with writing the book."

Mr. Shevchenko was born in Ukraine and studied at the Moscow State Institute of Foreign Relations, where he received a doctorate in 1954. Two years later, he joined the Foreign Ministry, becoming a disarmament specialist. He would write two books and numerous articles on disarmament and in time become one of the Soviet Union's leading spokesmen on disarmament, both at U.N. headquarters in New York and in Geneva. At 40, he became a special Soviet ambassador-at-large.

He gave up that privileged position and defected in the name of freedom, he said, angrily denying suggestions that he might have been blackmailed by the CIA. In an irony of history, one of the CIA officials who debriefed him after his defection was Aldrich H. Ames, who later would go to prison for selling U.S. secrets to the Soviet Union and Russia.

When the Soviet Union dissolved, Mr. Shevchenko disappeared from public view, and he spent his remaining years as a virtual recluse.

His wife, Elaine Jackson Shevchenko, died in 1990. Survivors include his third wife, Natasha, and two children from his first marriage. G. Cecil Woods Jr. Seminary President G.
