Greek authorities launched an investigation into the medical office where popular Greek pop singer Giorgos Mazonakis suffered a fatal heart attack at age 54, according to reports from the Athens News Agency (BTA) and Skai television. Prosecutors ordered the inspection after emergency medical staff failed to revive the musician following a procedure on Wednesday.
Prosecution Orders Inspection of Athens Medical Office
An inspection team from the Athens Medical Association arrived at the clinic on Thursday alongside police forces, acting directly on orders from the public prosecutor. According to BTA reporting, investigators examined whether the facility possessed the proper legal authorizations to perform the specific medical procedures scheduled for Mazonakis. Authorities are probing whether standard clinical protocols were fully observed during the visit and whether the attending personnel held the necessary professional qualifications.
Clinic Owners Questioned Regarding Plasmaferesis Procedure
Police questioned the owner of the clinic—a general practitioner—and his wife, a gynecologist, late Wednesday evening before releasing them without charges. According to Skai television coverage cited by BTA, the female physician informed authorities that Mazonakis had undergone a procedure known as plasmapheresis at the facility.
Health Minister Clarifies Licensing Restrictions
Health Minister Adonis Georgiadis addressed the regulatory status of the clinic, stating that while the establishment held a standard license for general medical practices, the procedure performed on the singer falls under strict limitations. According to the Health Ministry statements reported by BTA, plasmapheresis may legally be carried out only by a certified hematologist within a public hospital or inside a specialized clinic holding a specific, advanced license for the treatment.
