Abstract:
Objective To estimate the patterns and frequency of anomalous coronary origin with angiography in the Chinese elderly population and evaluate the correlation between anomalous coronary origin and development of coronary atherosclerotic stenosis. Methods A retrospective analysis was performed on the basis of angiographic data among elderly patients who underwent coronary arteriography in Beijing University First Hospital. Those with anomalous origin of coronary arteries were selected for further assessment and significant stenosis in coronary arteries was recorded.Results Among 2031 patients, 46 patients were found to have anomalous origin of coronary artery,with an incidence rate of 2.3%. Right coronary artery was the most common anomalous vessel, being involved in 26 patients (56.5%). The anomalous origin was more frequent in right coronary artery than in left coronary artery (41.3%). The most common anomaly was right coronary artery arising from left coronary sinus in 13 patients (28.3%). Significant atherosclerotic lesions in the anomalous arteries were seen in 37 patients (80.4%). Conclusions In Chinese elderly population, the anomalous origin of coronary artery is more frequent in right coronary artery, the most common anomaly resides in right coronary artery arising from left coronary sinus. The anomalous coronary artery increases risk for development of coronary atherosclerotic stenosis.
