Giant Left Anterior Descending Artery Aneurysm With an Unusual Direct Continuity to the Aortic Arch. 巨大左前降支动脉瘤伴与主动脉弓异常的直接连续性
A giant coronary artery aneurysm connected directly to the aortic arch is a rare and interesting cardiac pathology. When patients with coronary aneurysms and fistulas are not carefully investigated with advanced imaging techniques, surgeons may experience sudden problems intraoperatively, which may increase patients' morbidity. In this case report, we presented a surgical treatment and pre- and intraoperative surgical approaches to a patient with an interesting direct connection between a giant left anterior descending artery aneurysm and an aortic arch via a separate vessel, which was diagnosed thanks to a computed tomography scan, in a patient presenting with an acute myocardial infarction.

Embolization of two bleeding aneurysms with platinum coils in a patient with polyarteritis nodosa. 结节性多动脉炎患者两枚出血性动脉瘤的铂金弹簧圈栓塞治疗
We describe a patient with polyarteritis nodosa who developed a large retroperitoneal hemorrhage from a ruptured suprarenal capsule artery aneurysm. Platinum coils were embolized selectively during arteriography and successfully controlled the aneurysmal bleeding. The vasculitis was controlled ten weeks later but our patient developed anemia and computerized tomography scan revealed a large retrogastric hemorrhage. A further arteriogram confirmed the presence of a ruptured gastric coronary artery aneurysm. A second embolization was performed with complete success. Selective embolization of small arteries with coils should be considered a good alternative to surgery in patients with polyarteritis nodosa and hemorrhage from a ruptured aneurysm; arteriography may be considered a potent diagnostic and therapeutic tool in the management of the treatment of polyarteritis nodosa.

Large atherosclerotic left main coronary aneurysm--a case report and review of the literature. 大型动脉粥样硬化性左主干冠状动脉瘤——一例报告及文献综述
Coronary artery aneurysm (CAA) is a rare disorder, characterized by an abnormal dilatation of a localized portion of the coronary artery. It is usually diagnosed incidentally by coronary angiography. Over 50% of coronary artery aneurysms are of atherosclerotic origin. The natural history of coronary aneurysms is not well understood. Their presence is not always considered to be an operative indication; rather, the severity of the associated coronary artery disease (CAD) is what dictates a surgical approach. In the absence of obstructive CAD, the definitive treatment for this condition is unclear. The authors present the case of an isolated saccular left main coronary aneurysm with no associated flow-limiting CAD. The patient was treated medically with antiplatelet and anticoagulant medication with no adverse events at 3, 6, 9, and 12 months of follow-up.

[Giant left main coronary aneurysm without associated coronary lesions]. [不伴相关冠状动脉病变的巨大左主干冠状动脉瘤]
Left main coronary artery aneurysms are very infrequent (0.1%) and the majority are related to atherosclerotic obstructive lesions. Only a few isolated cases without associated coronary lesions have been reported until now. The management of these patients is not well established, thus both conservative and surgical treatments have been postulated. We present a case of giant left main coronary artery aneurysm with a diameter of 27.7 x 18.6 mm (the biggest reported until now) without coronary tree associated stenosis. It was treated conservatively with oral anticoagulation only and the 5 years evolution has been favourable.

Successful correction of congenital giant right coronary artery aneurysm with fistula to left ventricle. 先天性巨大右冠状动脉瘤伴左心室瘘的成功矫治
A 26-year-old male presented with radiographical evidence of enlargement of the right side of the heart. Echocardiography and computed tomography-scan revealed a diffuse, hugely enlarged right coronary artery (RCA) aneurysm, with the distal portion flowing directly into the left ventricle (LV). A radical correction operation was performed successfully. The RCA was reconstructed with an autograft of a greater saphenous vein after the aneurysm was removed and the RCA-to-LV fistula was closed. The postoperative course was uneventful and the patient was discharged on 12th day after operation.

[Pediatric case of congenital coronary artery fistula; surgical result and late changes in coronary artery aneurysm]. [先天性冠状动脉瘘的儿科病例；手术结果及冠状动脉瘤的晚期变化]
Congenital coronary artery fistula is an uncommon heart anomaly involving the coronary arteries. We report here a case of a 4-year-old boy who had a coronary fistula from the right coronary artery to the right ventricle, with a coronary aneurysm. He was asymptomatic, but the calculated ratio of pulmonary blood flow to systemic blood flow was shown to be high [pulmonary flow (Qp)/systemic flow(Qs)=1.78]. The coronary angiography showed that the right coronary artery was dilated beginning at the ostium and had an aneurysm at the acute marginal portion. A large spherical aneurysm approximately 20 mm in diameter was found to have been connected with coronary fistula opening into the right ventricle. Surgical repair by closure of the fistula under direct vision, partial resection and suture closure of the aneurysm was performed. Plication of the proximal portion of the right coronary artery was not performed, and the diffusely dilated artery was left untouched. After this operation, he recovered well under anticoagulant treatment with warfarin and aspirin. Postoperative angiography was performed 17 months after the surgery to evaluate morphological changes in the coronary artery. The angiography confirmed the closure of the fistula and the regression of coronary artery dilatation.

Giant aneurysm of the left atrial branch of the left circumflex artery with fistula. 左回旋支左心房支巨大动脉瘤伴瘘
Giant coronary artery aneurysm with a fistula is a rare condition. We present one of the largest aneurysms of left circumflex coronary artery territory, arising from the left atrial branch of the left circumflex coronary artery. It had a maximum diameter of 10 cm, with a fistulous connection to the right atrium. Total exclusion of the aneurysmal mass was achieved by ligation of the afferent artery, closure of the entry point from within the aneurysm, and closure of the fistulous communication from within the right atrium. The patient's postoperative course was uneventful.

Myocardial bridging with a coronary artery aneurysm and left ventricular stunning. 心肌桥伴冠状动脉瘤和左心室顿抑
The authors present a case demonstrating the unusual combination of myocardial bridging with a coronary artery aneurysm complicated by acute transient left ventricular dysfunction due to myocardial stunning. The pathophysiology and current insights into myocardial bridging, coronary aneurysms and myocardial stunning are briefly discussed. The literature reveals only one other reported case of coronary aneurysms associated with myocardial bridging. In addition, although there are several reports of angina and myocardial infarction complicating bridging, there is only 1 other report of myocardial stunning specifically.

Infective endocarditis complicated by mycotic aneurysm of a coronary artery with a perforated mitral valvular aneurysm. 感染性心内膜炎并发冠状动脉真菌性动脉瘤伴二尖瓣瓣膜瘤穿孔
Mycotic aneurysms are well-documented complications of infective endocarditis and occur frequently in the intracranial arteries. However, mycotic aneurysms of the coronary arteries are very rare, and there are few reports of the management of these lesions. The authors report the case of a 72-year-old woman with coagulase-negative staphylococcal endocarditis involving a perforated aortic valve, a perforated mitral valve aneurysm, and a large mycotic coronary artery aneurysm. After antimicrobial therapy, the patient underwent open-heart surgery with mitral and aortic valve replacement, coronary artery bypass, and resection of the mycotic coronary aneurysm. The authors present detailed serial echocardiograms of the mycotic coronary artery aneurysm, which was subsequently confirmed intraoperatively and pathologically.

Left main coronary artery aneurysm with fistula to superior vena cava: A challenging case. 左主干冠状动脉瘤伴上腔静脉瘘：一例具有挑战性的病例
Coronary artery fistulas (CAFs) are rare congenital coronary artery abnormalities, with direct communication between a coronary artery and a cardiac chamber, great vessel or other structure. We report here, a rare case of a 25-year-old male with CAF from the aneurysmal left main coronary artery to the superior vena cava detected on echocardiography and computerized tomography (CT) coronary angiography.
