In France, the incidence of sudden cardiac deaths (SCD) is approximately 30,000-50,000 per year. In the whole population, their cause is an atherosclerotic coronary disease in more than 80 % of cases, but in the young (35 years old), causes are various, including genetic, infectious, toxic, congenital anomalies, immune…Therefore a multidisciplinary approach is required for a better knowledge and prevention of SCD. In this article, we examine different aspects of autopsies and complementary investigations: histopathology, toxicology, biochemistry, genetics and virology. Six cases illustrate the importance of a multidisciplinary approach. There are two categories of autopsies: medicolegal or medical. Medicolegal autopsies are requested by a judicial authority when a death is considered suspicious. These autopsies are performed by forensic doctors. Most of them are not pathologists. During the autopsies, blood and tissue samples are taken, but analyses are done only at the request of the judicial authority if the analyses are useful for the truth. Consequently, the cause of death can remain uncertain. Medical autopsies are performed by a pathologist at the request of a clinician. The family consent is required. Useful analyses are performed, which is essential for the determination of a precise cause of death. In the young, "molecular autopsy", in addition to histology and other analyses, is essential in preventing genetic causes of SCD. |
