Joan Rivers’ daughter Melissa Rivers is convinced the iconic comedienne would still be alive if medics at New York’s Yorkville Endoscopy clinic had been better prepared for an emergency after the star stopped breathing during a routine throat operation last September.

“In my opinion, it was 100 per cent preventable,” Rivers is telling the media. “Yes, it was a tragic accident. If something happens, and everyone does everything properly, things happen… You live with it. When it’s error after error, after error, after error, after behaviors that you can not even begin to get your head around – you get mad.”

Melissa Rivers filed suit against bosses at the medical center in January.

The late comedian stopped breathing during a routine procedure at Yorkville Endoscopy in New York last September. A medical examiner ruled she died of brain damage due to lack of oxygen.

“Filing this lawsuit was one of the most difficult decisions I’ve ever had to make,” Melissa Rivers said in a January statement.

“What ultimately guided me was my unwavering belief that no family should ever have to go through what my mother, Cooper and I have been through. The level of medical mismanagement, incompetency, disrespect and outrageous behavior is shocking and frankly, almost incomprehensible. Not only did my mother deserve better, every patient deserves better. It is my goal to make sure that this kind of horrific medical treatment never happens to anyone again.”

Some of the allegations made against the clinic include the use of unlicensed medical staff as well as doctors taking “selfie” photos with an unconscious Rivers in the operating room.
