Investigation into Greek singer's death focuses on disputed plasmapheresis treatment

Authorities are piecing together the final hours of singer Giorgos Mazonakis, who suffered cardiac arrest during a plasmapheresis session at a private practice in Athens’ Kolonaki district. The 56-year-old female doctor who ran the clinic and her 58-year-old husband, both responsible for the practice, are detained in Korydallos prison and maintain their innocence. Investigators are scrutinizing the legality of the plasmapheresis procedure, the possible use of sedation, and whether staff had the necessary equipment, such as a defibrillator, to handle the emergency.

Digital records, security-camera footage, phones and computers seized from the clinic are being analyzed to map events from the procedure’s start at 2:14 p.m. to the singer’s collapse at about 3:45 p.m. A nurse reported noticing movement in Mazonakis’s arm at 3:22 p.m., and a call was placed to an anesthesiologist shortly before emergency services were contacted. An unverified allegation suggests the doctor sought assistance from an AI platform while the patient was in critical condition. The forensic report identified myocardial ischemia, but toxicology and histology results are still pending to determine the exact cause of death.
