Genetic Diagnosis in Sudden Cardiac Death: The Crucial Role of Multidisciplinary Care

Abstract

Sudden death, especially at a young age, may be caused by an underlying genetic cause. Hereditary conditions with an increased risk of sudden death at a young age include cardiomyopathies, arrhythmia syndromes, and hereditary thoracic aortic aneurysms and dissections. The identification of a genetic cause allows for genetic testing and cardiological surveillance in at-risk relatives. Three sudden death cases from our hospital illustrate the value of autopsy, genetic, and cardiological screening in relatives following a sudden death. On autopsy, histology consistent with hereditary cardiomyopathy is a reason for the referral of relatives. In addition, in the absence of an identifiable cause of death by autopsy in young sudden death patients, arrhythmia syndrome should be considered as a potential genetic cause.
