ABSTRACTPurposeThorough investigation of sudden cardiac death (SCD) in those aged 1-40 years commonly reveals a heritable cause, yet access to postmortem genetic testing is variable. We explore practices of postmortem genetic testing and attitudes of healthcare professionals worldwide.MethodsA survey was administered among healthcare professionals recruited through professional associations, social media and networks of researchers. Topics included practices around postmortem genetic testing, level of confidence in healthcare professionals’ ability, and attitudes towards postmortem genetic testing practices.ResultsThere were 112 respondents, with 93% from North America, Europe and Australia and 7% from South America, Asia and Africa. Only 30% reported autopsy as mandatory, and overall practices were largely case-by-case and not standardised. North American respondents (87%) more often perceived practices as ineffective compared to those from Europe (58%) and Australia/New Zealand (48%, p=0.002). Where a heritable cause is suspected, 69% considered postmortem genetic testing and 61% offered genetic counseling to surviving family members; financial resources varied widely. Half believed practices in their countries perpetuated health inequalities.ConclusionPostmortem genetic testing is not consistently available in the investigation of young SCD despite being a recommendation in international guidelines. Access to postmortem genetic testing, guided by well-resourced multidisciplinary teams, is critical in ascertaining a cause of death in many cases.
