| Abstract: | A case of a 35-year-old male who died suddenly after a blow on the chest by his opponent during a quarrel. From both the clinical and autoptical examinations there was no evidence of trauma found anywhere, even in the chest. The heart was the only one of all the internal organs whereon significant pathologic changes were observed during autopsy. It's lesions were as follows: (I) The right ventricle was greatly enlarged simply due to the simple right ventricular outflow tract stenosis (SRVOTS); the heart weight was 587 g. (II) All the main trunks of coronary arteries were involved by atherosclerosis. In addition, the appearance of the lumen at the proximal end of the left anterior descending artery narrowed by an atheromatous plaque (grade II) was completely occluded by a newly formed thrombus. The authors believed that both the coronary atherosclerotic changes and the enlarged heart due to the SRVOTS played a role in the pathogenesis of death (Kelberlus, H.E. and Wellens, H.J.J., Sudden Death, Developments in Cardiovascular Medicine, Vol. 4, Martinys Nijhoff Publishers, London, 1980, pp. 34-48; Jinming, Qin, A study of cardiac sudden death (51 cases) on the clinical pathologic view, Tianjin Med., 8 (1980) 458-461). The quarrel and blow were the disposing factor. |
