Melissa Rivers has said that her mother Joan Rivers' death was 100 percent preventable.
The American actress said in an interview on Today show that she just couldn't believe what she was seeing and it became very surreal, E! Online reported.
The 47-year-old actress questioned her mother's death by saying that, one should have paid attention to the vital signs or may be having a properly equipped crash cart.
The 81-year-old comedienne died a week after undergoing a minor throat procedure on her vocal chords after suffering from cardiac arrest during the surgery and Melissa then filed a malpractice suit against Yorkville Endoscopy, where her mom's complication occurred.
