BACKGROUND: Since 1967, numerous case reports have described fibromuscular alterations of the sinus node artery and/or the atrioventricular node artery as a potential cause of death. However, the prevalence of these changes in a healthy population has only rarely been investigated systematically.
METHODS: The arteries of the cardiac conduction system were studied systematically, by means of routine histology, in 100 cases of victims aged 0 to 40 years with a nonnatural cause of death.
RESULTS: Microscopic alterations were seen in the walls of sinus node arteries in 52 out of 100 cases, in the walls of atrioventricular node arteries in 63/100 cases, and in the walls of small vessels in 60/100 cases.
CONCLUSIONS: The results demonstrate that microscopically detectable findings of the cardiac conduction system arteries similar to fibromuscular dysplasia do not indicate a defined disease and should not be considered as a cause of death when there are no macroscopic findings in the coronary arteries.
