A postmortem coronary angiography technique employing aortic injection of contrast medium and double contrast visualization of the aortic bulb and large epicardial coronary trunks was applied to the study of coronary ostia in a series of 124 deaths from acute myocardial infarction and a series of 89 sudden deaths without recent infarction and 42 violent deaths. A stenosis of 50 per cent or more of the lumen was found in the right ostium in 45 per cent and in the left ostium in 8 per cent of infarct cases. The corresponding figures in sudden deaths were 37 per cent on the right and 4.5 per cent on the left side, and in violent deaths 7 per cent in the right ostium and none in the left. Most ostial stenoses were caused by coronary atherosclerosis. In 9 patients, two with a recent infarct and 7 sudden deaths, an ostial stenosis was the only stenosed site in the coronary arterial tree. Of theses 9 patients, 7 were known to have suffered from symptomatic heart disease during life, chest pain on effort and arrhythmias being the most common complaint.
一种采用向主动脉注射造影剂以及对主动脉球部和心外膜大冠状动脉主干进行双重造影显影的尸体冠状动脉造影技术，被应用于对一系列124例急性心肌梗死死亡病例、89例近期无梗死的猝死病例以及42例暴力死亡病例的冠状动脉口的研究。在梗死病例中，发现右冠状动脉口管腔狭窄50%或以上的占45%，左冠状动脉口的占8%。猝死病例中的相应数字为右侧37%，左侧4.5%；暴力死亡病例中，右冠状动脉口为7%，左冠状动脉口无狭窄。大多数开口处狭窄是由冠状动脉粥样硬化引起的。在9例患者中，2例近期有梗死，7例为猝死，开口处狭窄是冠状动脉树中唯一的狭窄部位。在这9例患者中，已知有7例在生前患有症状性心脏病，最常见的症状是劳力性胸痛和心律失常。
