[Sudden cardiac death of a young male due to fibromuscular dysplasia of the left coronary artery].

Arteriosclerosis and its complications are the most frequent cause of death due to cardiovascular diseases. Other different, considerably rare arterial changes can lead to a fatal result as well. The authors presented a case of a 31-year-old male. Postmortem examination revealed a narrowed lumen and thrombosis of the left coronary artery due to fibromuscular dysplasia and scarification of the myocardium. Hemodynamic disturbances due to left ventricular failure lead to the death of the young adult.
