Domenico's death after a transplant continues, with health workers interviewed in Naples and Bolzano.

The investigation into the death of Domenico Caliendo, the two-year-and-four-month-old boy who died at Naples' Monaldi Hospital after an unsuccessful heart transplant, continues unabated. NAS officers are currently interviewing the medical personnel involved in the incident, both in the Campania capital and in Bolzano.

The investigations are being conducted by the NAS of Naples at the Monaldi Hospital and, concurrently, by the Trento unit at the South Tyrolean health facility. The investigation focuses on the entire chain of operations that led to the organ removal and subsequent transplant.

Seven doctors are currently under investigation for manslaughter. These include the members of the team who performed the heart removal in Bolzano and the doctors who performed the transplant in Naples.

According to what emerged during the investigation, the organ arriving in the Campania capital was damaged by the excessively low temperatures generated by the use of dry ice during transport, instead of the ice traditionally used in these procedures.

The judicial investigation is continuing through the preliminary hearing format, which should conclude by September 11th, although a possible postponement due to the technical contributions of the parties' consultants cannot be ruled out.

A crucial milestone has already been set for April 28, when, at the Institute of Forensic Medicine in Bari, court-appointed experts and consultants for the suspects will conduct a series of tests on both hearts seized as part of the investigation: that of little Domenico and the one removed in Bolzano. These tests could prove crucial in clarifying the causes of the transplant failure and any potential culpability.
