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.

Acute coronary syndrome in a patient with a single coronary artery arising from the right sinus of Valsalva

Coronary artery anomalies are usually encountered as coincidental findings during coronary angiography or at autopsy.Life threatening symptoms,such as arrhythmias,syncope,myocardial infarction,or sudden death,can occur in up to 20% of patients.However,the majority of anomalies(80%) are benign and asymptomatic.A single coronary artery(SCA) is one of the most rarely seen coronary anomalies with an incidence of 0.05%.We report the case of a 55-year old male patient who presented with symptoms of chest pain associated with an acute myocardial infarction.Coronary angiography revealed an anomalous left main coronary artery(LMCA) originating from the right coronary ostium,and an occluded distal right coronary artery.The occluded distal right coronary artery was successfully treated by thrombosuction and stenting.In order to confirm the origin and course of the SCA,multi-slice computed tomography(MSCT) of the heart was performed after coronary angiography.MSCT showed that the anomalous LMCA originated from the right coronary artery ostium and then passed the interventricular septum,instead of being intra arterial,and under the right ventricular infundibulum.The anomalous LMCA was classified as R-Ⅱ S subtype according to Lipton’s classification.

Coronary artery anomalies: Anomalous origin of the left coronary artery and circumflex branch in two patients

Coronary anomalies may be isolated defects or accompany congenital malformations of the heart. The determination of these anomalies is important in the treatment approach and the surgical procedure in bypass and valve surgery. The present article reports on clinical and angiographic findings in two patients with coronary artery anomalies -one patient with an anomalous origin of the left coronary artery from the right aortic sinus, and another patient with an anomalous origin of the circumflex branch of the left coronary artery from the right coronary artery.     

Anomalies of coronary arteries

Concealed undiagnosed congenital anomalies of coronary arteries (CACA) can cause sudden death of young men. Isolated CACA are detected at 0.6-1.8% of coronary angiographies. Classification of CACA (2002) includes anomalous origin of coronary artery from pulmonary artery, anomalous origin of coronary artery from the aorta, congenital atresia of the left main coronary artery, coronary arteriovenous fistula, coronary artery with myocardial bridge, coronary artery aneurism, coronary artery stenosis. In most cases coronary artery anomalies for long time remain asymptomatic. Clinical picture of anomalous origin of coronary artery from pulmonary artery is often erroneously related to cardiomyopathy or myocarditis because of signs of heart failure. Modern methods of visualization are used for diagnosis of CACA: echocardiography (transthoracic and transesophageal), computer angiotomography (electron beam tomography, multispiral computer tomography), magnetic resonance angiography, thallium stress scintigraphy, single photon positron emission tomography, dobutamine stress echocardiography, endovascular ultrasound study. Coronary angiography is the gold standard for diagnosis of congenital anomalies of coronary arteries. Drug therapy, transluminal balloon angioplasty with stenting or surgical revascularization are indicated to patients with overt clinical picture.
