Giant right coronary artery aneurysm with fistulous connection to the coronary sinus: diagnosis and management. 巨大右冠状动脉瘤伴冠状静脉窦瘘连接：诊断与治疗
This report describes the case of a giant aneurysmal right coronary artery connecting to the coronary sinus near its opening into the right atrium in a 70-year-old woman who presented with a recent onset of congestive heart failure. By coincidence, a secundum atrial septal defect was also present. The diagnosis and surgical management of this uncommon pathology are described.

Successful treatment of giant right coronary artery aneurysm mimicking right atrium thrombus--a case report. 模拟右心房血栓的巨大右冠状动脉瘤的成功治疗——一例报告
Coronary artery aneurysms are very rare abnormalities in patients undergoing coronary angiography. Clinical manifestation is usually that of coronary artery disease, and acute myocardial infarction. We present the case of a patient admitted to the Department of Cardiac Surgery due to coronary artery disease and the presence of thrombus in right atrium of the heart diagnosed by transthoracic echocardiography. Coronary angiography showed occlusion of the right coronary artery (RCA) in its middle portion, 20% stenosis of the stem of the left coronary artery in distal portion and occlusion of circumflex coronary artery (CX) and the second obtuse marginal branch (OM 2). During surgery no tumor was found within the right atrium, but right coronary artery giant aneurysm was revealed. The totally thrombosed aneurysm was removed with additional performance of two venous grafts to RCA and OM 2. The postoperative course was uneventful.

Case report: incidental finding of a giant cardiac mass. 病例报告：巨大心脏肿块的偶然发现
Coronary artery fistula (CAF) is a rare anomalous connection between a coronary artery and another coronary artery, major vessel, or cardiac chamber. Prevalence of CAF is reportedly 1% to 2% in patients who undergo coronary angiography.1 One of the most common complications of CAF is formation of a coronary artery aneurysm (CAA). A study conducted by Said and colleagues in 1995 found that CAA formation was present in 26% of patients who had proven CAF by way of angiography.2 Although a precise definition of the term "giant" CAA is still lacking, it generally refers to a dilatation that exceeds the reference vessel diameter by four times.3 We report an interesting case of a 38-year-old patient who was incidentally found to have a presumed large right ventricular aneurysm, which after an open-heart surgery was identified as a CAF with formation of an unruptured giant CAA.

Giant right coronary artery aneurysm in an adult male patient with non-ST myocardial infarction. 一名成年男性非ST段心肌梗死患者的巨大右冠状动脉瘤
The combination of a giant coronary aneurysm with multiple coronary aneurysms in adults is an extremely rare entity--especially in atherosclerotic patients, since it is most commonly associated with Kawasaki disease in children. We report an interesting case of a 59-year-old male patient with multiple atherosclerotic aneurysms of the left coronary system and a giant aneurysm of the right coronary artery. The patient was admitted to our hospital because of a non-ST myocardial infarction. Diagnosis was established by echocardiography, computed tomography angiogram, and coronary angiography. In view of the clinical symptoms and the extent of the giant right coronary aneurysm, with the associated risk of rupture, the patient was successfully treated with urgent surgical intervention. We also present a review of the current literature on this anomaly and a statistical analysis of all atherosclerotic giant coronary artery aneurysms previously reported.

Autologous Patch Angioplasty of a Giant Right Coronary Artery Aneurysm and Coronary Stenosis in Kawasaki Disease. 川崎病中巨大右冠状动脉瘤和冠状动脉狭窄的自体补片血管成形术
We describe our management of a 2-year-old patient with Kawasaki disease with a giant proximal right coronary artery (RCA) aneurysm and a >99% RCA ostial stenosis. After median sternotomy and cardioplegic arrest of the heart, we opened the aorta and cut into the RCA ostium past the stenosis and giant aneurysm. The RCA was reconstructed with an autologous pericardial patch. Cross-clamp and cardiopulmonary bypass times of 84 minutes and 114 minutes, respectively, were required. Our approach avoids mammary harvesting and grafting in such small patients while successfully treating ischemia and hopefully prevents further aneurysmal dilation over time.

Left main coronary artery aneurysm. 左主干冠状动脉瘤
Left main coronary artery aneurysms (LMCA) are usually asymptomatic and are rarely encountered during coronary angiography. The most serious complications include coronary thrombosis, acute myocardial infarction and sudden death. Atherosclerosis is the most common cause, although several autoimmune diseases and congenital abnormalities have been associated with the presence of coronary aneurysms. The case of a symptom-free 63-year-old man with a giant LMCA and severely ectatic coronary arteries is presented.

Coronary artery aneurysm with thrombus evaluated by multi-detector row computed tomography. 多排螺旋计算机断层扫描评估的伴血栓冠状动脉瘤
This is a case report of a 60-year-old woman with acute myocardial infarction (AMI) who had coronary aneurysms and thrombus in the right coronary artery detected by multi-detector row computed tomography (MDCT). In this case, MDCT was useful for clarifying the thrombus complicated with coronary aneurysms, which was considered to be the cause of AMI. Thus, warfarin was started as an anticoagulant therapy for thrombus.

Coronary artery aneurysms after drug-eluting stent implantation. 药物洗脱支架植入术后冠状动脉瘤
Drug-eluting stents (DES), which locally elute antiproliferative drugs, can dramatically inhibit neointimal growth. However, several pathological studies have indicated that DES may delay healing after vascular injury, and DES implantation may be theoretically associated with a risk of coronary artery aneurysm formation. Coronary aneurysms have been reported from 3 days to up to 4 years after DES implantation procedures, with varying clinical presentations. The incidence of coronary artery aneurysms after DES implantation is low within the first 9 months, with a reported incidence of 0.2% to 2.3%, a rate similar to that reported after bare-metal stent (BMS) implantation (0.3% to 3.9%) in the DES versus BMS randomized trials. However, the true incidence of coronary aneurysms in an unselected patient population is still largely unknown. This article reviews the published literature on coronary artery aneurysms specifically relating to DES.

Coronary Artery Aneurysm After Bioresorbable Scaffold Implantation. 生物可吸收支架植入术后冠状动脉瘤
The clinical course of coronary artery aneurysms after drug-eluting stent implantation is variable. Some aneurysms naturally resolve, but some can lead to complications such as stent thrombosis. In order to avoid such complications, it is important to reduce as much as possible the chance of exposing causal factors, and intravascular imaging may be needed in order to accurately assess the results of stent deployment and apposition. In the presented case, intravascular imaging was shown to be useful in accurately assessing the results of bioresorbable stent deployment and apposition.

Left main coronary artery aneurysm following percutaneous transluminal angioplasty: a report of a case and review of the literature. 左主干冠状动脉瘤随访... (原文已截断)
Since its introduction in 1977, the number of PTCAs and its indications have grown. Along with more frequent usage, newer complications have been reported. Aneurysm of left main coronary artery is rare. This report describes the formation of a new non-obstructing aneurysm in the left main coronary artery after PTCA of left circumflex artery. The patient has had 7 yr of follow-up with a benign clinical course.
