Histologic spectrum of the cardiac conducting tissue in non-natural deaths under 30 years of age: an analysis of 43 cases with special implications for sudden cardiac death
We examined the pathology findings of the cardiac conduction system in 42 human autopsies who were considered to have died an accidental death. Abnormalities in serial sections of the conduction system were found in seven and of these three had an accessory pathway in the conduction system. In one of these there was mild Ebstein's anomaly (ME), two had fibromuscular dysplasia of the atrioventricular node artery with mitral valve prolapse, and two others had abnormal routes showing fragmentation of the bundle of His with ME. A full investigation of the cardiac conduction system can therefore be useful for determining the precise cause in cases of accidental death.
