LOS ANGELES - The family of Bill Paxton has filed a wrongful death lawsuit against a Los Angeles hospital and the surgeon who performed the actor's heart surgery shortly before he died.

The suit filed against Cedars-Sinai Medical Center alleges the surgeon, used a "high risk and unconventional surgical approach" that was unnecessary and that he lacked the experience to perform, and that he downplayed the procedure's risks.

And it alleges the hospital knew the surgeon, Dr. Ali Khoynezhad, tended to "engage in maverick surgeries and show suboptimal judgment."

The misguided treatment caused Paxton to suffer excessive bleeding, cardiogenic shock and a compromised coronary artery, the suit alleges.

Paxton's death certificate says he died Feb. 25, 2017, from a stroke, 11 days after surgery to replace a heart valve and repair aorta damage. He was 61.

"Bill Paxton and his family trusted the physicians and staff at this medical facility but instead Cedars-Sinai betrayed their trust," the family's attorney Bruce Broillet said in a statement. "The surgeon's actions resulted in this tragic and preventable death."

Paxton's widow, Louise, and children, James and Lydia, brought the lawsuit. It seeks unspecified damages and reserves the right to add more defendants who work for the hospital as their roles and names become clear. - AP
