The family of late actor Bill Paxton has sued the surgeon who operated on him, as well as the hospital where he was treated last year, claiming wrongful death.

Paxton died Feb. 25, 2017 at 61, 11 days after undergoing heart surgery at Cedars-Sinai Medical Center in Los Angeles.

ET confirmed reports the suit filed against the medical centre as well as Paxton’s surgeon, Dr. Ali Khoynezhad, alleges wrongful death due to a “maverick” operation, that he “intentionally performed unnecessary heart surgery,” and that the actor and his family were not properly informed of the risks.

“We are pursuing accountability and justice from a physician and a hospital that failed to adequately protect Mr. Paxton,” an attorney for Paxton’s family said in a statement.

The suit is seeking damages in excess of $25,000, and the plaintiffs are demanding trial go before a jury for decision.

According to the death certificate, Paxton’s official cause of death was a stroke, and that he had a heart disease known as bicuspid aortic valve.

The “Twister” star underwent surgery last year due to an aortic aneurysm, which was potentially life threatening.

“State and federal privacy laws prevent us from commenting about patient care without written authorization,” the hospital said in a statement Tuesday. “Nonetheless, ‘[n]othing is more important to Cedars-Sinai than the health and safety of our patients. These remain our top priorities. One of the reasons for our high quality is that we thoroughly review concerns about any patient’s medical care. This process ensures that we can continue to provide the highest quality care.”
