In addition, 11 reports have been submitted over the suspected inappropriate use of medical devices, the Zurich cantonal prosecutor's office said on Tuesday.

The complaints have been filed against persons unknown and are being examined alongside the other reports. Given the complexity of the case, the investigation is expected to take some time.

Prosecutors must first establish whether there is sufficient evidence of any criminal offences. Investigators will also examine who the allegations relate to.

To support the investigation, the Zurich cantonal prosecutor's office has set up a dedicated team to look into the incidents at the cardiac surgery department of University Hospital Zurich.

The team comprises four prosecutors with expertise in medical criminal law, white-collar crime and offences involving public officials.

The“Oberholzer report”, published in early May, found that between 2016 and 2020, some 4,500 operations at the hospital's Clinic for Cardiac Surgery led to between 68 and 74 more deaths than would have been expected based on statistical estimates.

The clinic's then director, Francesco Maisano, also used a device he had helped to develop and is alleged to have benefited from it financially.
