A 27-year-old woman, who had received mitral valve repair for mitral regurgitation resulting from infective endocarditis, was admitted for a close examination of abnormal echocardiographic findings in the left atrium. Transthoracic echocardiography showed trivial mitral regurgitation with normal left ventricular contraction and dilatation of the coronary sinus. Auscultation revealed a grade 2 continuous murmur along the left sternal border. Transesophageal echocardiography demonstrated a marked dilatation of the coronary sinus just behind the posterior wall of the left atrium and turbulent blood flow in the dilated coronary sinus. Cardiac catheterization showed no significant step-up of oxygen saturation in the right heart and normal pulmonary artery pressure. Coronary angiography revealed a markedly dilated and tortuous circumflex coronary artery connected to the coronary sinus through a fistula. A left circumflex artery with a fistulous connection to the coronary sinus is extremely rare. 相似文献

Coronary artery anomalies represent a diverse group of congenital disorders characterized by abnormalities of coronary arteries anatomy. We describe an extremely rare case of giant torturous left circumflex artery draining to the right atrium manifesting by palpitations and atrial fibrillation. 相似文献

A 62-year-old woman with six months history of dizziness was admitted to our hospital. A large mass in the left atrium was detected by transthoracic echocardiography. Coronary angiography showed two feeding arteries from the right coronary artery and left circumflex artery to the left atrium. Chest computed tomography, coronary computed tomographic angiography and contrast echocardiography were performed. Those showed multiple intratumoral neovascularities from surface of the mass. After those examinations, the mass was completely resected. Histopathologic examination confirmed the diagnosis of cardiac myxoma. There was no abnormal remnant mass, based on a follow-up transthoracic echocardiography.KEYWORDS : Myxoma, coronary angiography, multiple neovascularity 相似文献

Congenital left main (LM) coronary artery to right atrium fistulas with progression to aneurysm development are rare. Most patients remain asymptomatic, but for those with progressive symptoms, intervention is required. However, there are potential life-threatening complications associated with surgical intervention. We present a case of an extremely rare markedly aneurysmal LM to right atrial fistula treated with surgical ligation complicated by inferolateral ST-elevation myocardial infarction several days post-operatively treated successfully using mechanical aspiration thrombectomy, a stent-retriever, balloon angioplasty, and subsequent intravascular ultrasound-guided percutaneous coronary intervention with drug-eluting stent. 相似文献

Single coronary artery: right coronary artery originating from distal left circumflex 总被引:1,自引:0,他引:1

This report describes a patient with single coronary artery, in whom the right coronary artery originated from the distal left circumflex. However, this anomaly was not of clinical significance based on atypical nature of chest pain, negative thallium exercise test and absence of coronary obstruction. 相似文献

We present the case of a 67-year-old female who was admitted to our institution because of anginal chest pain. Selective coronary angiography revealed separate ostial origins of the left anterior descending (LAD) artery and the right coronary artery (RCA) from the right coronary sinus (RCS). The left circumflex (LCx) coronary artery arose from the proximal RCA. The left anterior descending had an anterior free wall and the LCx had a retroaortic course. To our knowledge, this type of combination of anatomical variation of coronary circulation has not been described in the literature. 相似文献

We report two very unusual cases of agenesis of the right coronary ostium with continuation of the left circumflex artery as the right coronary artery. The recognition of the anomaly in the first case lead to a better understanding of this finding in the second case, which translated into shorter procedure time, less contrast volume, and fewer catheter manipulations. 相似文献

Coronary angioplasty can provide excellent means of revascularization of anomalous coronary arteries. Successful application of angioplasty to these vessels requires angiographic knowledge of their course, structure and appropriate equipment selection. Advancement of stent delivery systems in such cases requires good support with the possibility of selective cannulation and deep engagement of the guiding catheter. We report a case of stent placement in an anomalous circumflex artery arising from the right coronary artery. 相似文献

A case of acute myocardial infarction (AMI) of the distal left circumflex, near the origin of an aberrant right coronary artery is presented. Coronary stenting was successfully performed. According to several reports, this anomaly is a common site for coronary atherosclerosis, but this is the first report of AMI. 相似文献

Coronary artery fistulae that communicate with the left ventricle are quite rare; those accompanied by sinus-node dysfunction are even more unusual. We report 2 cases of congenital coronary-artery-to-left-ventricle fistula with sinus-node dysfunction. In each of these patients, fistulae arose from both left and right coronary arteries. One patient had, in addition, a right coronary artery fistula that communicated with his right ventricle. Sinusnode dysfunction encountered in these 2 patients was likely caused by chronic general ischemia arising from a steal syndrome associated with the fistulae. 相似文献

目的:对比分析右冠状动脉(RCA)与左回旋支(LCX)闭塞的急性下壁心肌梗死患者的心电图特征、心功能和预后。方法:90例首次急性下壁心肌梗死患者,进行常规心电图及冠状动脉造影。RCA闭塞组(RCA组)63例,LCX闭塞组(LCX组)27例,所有患者均在发病24 h内行直接冠状动脉介入术。术后2周行99mTc-MI-BI心肌灌注断层显像测定心肌梗死面积,并行心血池显像测定左室射血分数(LVEF)。观察住院期间心律失常、心力衰竭或心源性休克的发生率及病死率。结果:①RCA组下壁并右室梗死的发生率显著高于LCX组(P<0.01),而并发侧壁梗死的发生率显著低于LCX组(P<0.01)。②RCA组Ⅲst↑>Ⅱst↑及aVL st↓>Ⅰst↓的发生率也显著高于LCX组(P<0.01)。③RCA组肌酸激酶同工酶峰值及心肌梗死面积均大于LCX组(P<0.05)。④RCA组LVEF低于LCX组(P<0.05)。结论:RCA闭塞较LCX闭塞的急性下壁心肌梗死患者心肌梗死面积大,心功能和预后差。 相似文献
