Family files $10 million suit after fatal valve surgery at Kansas hospital
A daughter is suing HaysMed and Dr. Roberto Cervera for $10 million after her father, Stephen Richter, died Oct. 1, 2024 during an aortic valve replacement at HaysMed. The suit claims negligence across multiple aspects of care, including evaluation, medical history, informed consent, management of cardioplegia, timing, and equipment readiness. Both sides deny wrongdoing; HaysMed has expressed sympathy but cannot comment due to pending litigation, and a venue-change request was denied. No hearing date has been set yet.
