Acerbic comedian and fashion critic Joan Rivers “rested comfortably” at a New York hospital where she was admitted after she suffered a cardiac arrest and stopped breathing during a vocal cord procedure, a spokeswoman said.

There was no change in condition from late on Thursday when daughter Melissa Rivers issued a statement saying her 81-year-old mother was resting comfortably, said Mount Sinai Hospital spokeswoman Lucia Lee.

Rivers had gone to a New York clinic for a vocal cord procedure.

New York City Fire Department spokesman Jim Long said a patient reported to be in cardiac arrest had been taken from Yorkville End-oscopy to Mount Sinai by emergency workers at mid-morning.

Long declined to name the patient due to privacy concerns, but the NBC television affiliate in New York said it was Rivers and that she had stopped breathing during a procedure on her vocal chords.

One of America’s best-known comedians, Rivers is considered a pioneer for women in stand-up comedy.

Rivers’s peers in the 1960s comedy club scene of New York’s Greenwich Village included Bill Cosby, Richard Pryor, Woody Allen and George Carlin, but she said she never felt like she was part of their clique.

In 1983, she earned one of the biggest gigs in the business when The Tonight Show host, the late Johnny Carson, crowned her as his regular guest host.

Her brash and self-deprecating routine found new life on the awards show circuit and in recent years she trained her biting wit and profanity-laced comment on the fashion faux pas of Hollywood’s celebrities.

In an age of political correctness, her no-holds-barred style has stood out in the crowded world of celebrity TV, as has her ability to make fun of herself, including her penchant for plastic surgery.

Aside from her role on Fashion Police, she has in recent years starred alongside her daughter in the WE TV reality show Joan & Melissa: Joan Knows Best?
