Project description:We present a case of 48-year-old male who presented with coronary artery fistula draining into left ventricle. Transthoracic echocardiography showed abnormal blood flow draining into left ventricle, with enlarged coronary arteries and multiple vascular structures around ventricular myocardium. Coronary computed tomography revealed dilatation of entire left coronary artery which was wrapping around left ventricle, and draining into the posterior side of left ventricle. He did not undergo any invasive treatment, because he was not symptomatic.

Project description:RationaleCases of coronary artery fistula having a connection with the cardiac cavity are rare. Here, we report a case in which 2 coronary arteries empty into the left ventricular cavity together.Patient concernsA 63-year-old woman who was diagnosed as having hypertension 20 years prior presented with dyspnea.DiagnosesThe coronary angiography revealed coronary artery fistula.InterventionsChest X-ray showed pulmonary edema. Transthoracic echocardiography revealed moderately decreased left ventricular (LV) function and increased LV end-diastolic volume and mass index. Coronary angiography and cardiac computed tomography revealed that 2 coronary arteries joined together at the distal end and directly drained into the left ventricular cavity bypassing the myocardial capillary vessels. We started medical treatment for heart failure with an angiotensin-converting-enzyme inhibitor, loop diuretic, and spironolactone.OutcomesThe pulmonary edema improved rapidly. The patient did not experience dyspnea after discharge, and follow-up echocardiography showed improved cardiac function.Main lessonCoronary artery fistula could be found incidentally on coronary angiography performed for varied reasons. Physicians must decide carefully whether the fistula needs to be treated in view of the clinical context.

Project description:Coronary-cameral fistulas are rare congenital malformations, often incidentally found during cardiac catheterizations. The majority of these fistulas are congenital in nature but can be acquired secondary to trauma or invasive cardiac procedures. These fistulas most commonly originate in the right coronary artery and terminate into the right ventricle and least frequently drain into the left ventricle. Depending upon their size and location, coronary-cameral fistulas can lead to congestive heart failure, myocardial infarction, and bacterial endocarditis. We describe a case of 49-year-old woman who presented with worsening exertional dyspnea and leg swelling. Transthoracic echocardiogram revealed an ejection fraction of 35%. Cardiac catheterization demonstrated a fistula connecting the left anterior descending artery and the first obtuse marginal artery to the left ventricle. In this report, the authors provide a concise review on coronary fistulas, complications, and management options.

Project description:BackgroundCoronary artery fistula complicated with giant coronary artery ectasia (CAE) is a rare cardiac malformation, and its surgical indications and treatment strategies still need further discussion.Case summaryIn this case, a 41-year-old man had complained of occasional dizziness for 2 years, but he did not seek medical attention until he started to feel palpitations. A right coronary artery (RCA)-left ventricular (LV) fistula with giant RCA of diffuse ectasia was firstly revealed by transthoracic echocardiography. A widened left ventricle and significantly constricted right atrium and right ventricle were also detected by three-dimensional coronary artery computed tomography. Surgical treatment, including the repair of the RCA-LV fistula, the resection and reconstruction of the dilated RCA and coronary artery bypass grafting (CABG) under hypothermic cardiopulmonary bypass, were performed to correct the malformation. The patient presented a favourable health condition without any discomfort at the 1-year follow-up.DiscussionCAE can be caused by various congenital or acquired factors. Surgical treatment, such as transcatheter embolization excision, surgical ligation or resection for symptomatic patients with CAE three times or larger than the reference diameter, has been reported to have satisfactory results. Additionally, CABG can be selected if myocardial perfusion is compromised and the distal branch is of reasonable size. In this case, the giant ectasia of the RCA may have been a consequence of the congenital RCA-LV fistula. Atherosclerosis, with calcified plaques in the RCA, and the patient's long-term history of smoking may have contributed to the development of giant ectasia of the RCA.

Project description:BackgroundCoexistence of coronary artery fistulas and atherosclerotic coronary artery disease (CAD) is rare.Case summaryWe present a unique case of a patient initially presenting with an anterior ST-elevation myocardial infarction, subsequently found to have two-vessel CAD and an aneurysmal left coronary-to-right pulmonary artery fistula.DiscussionAfter discussion with the patient and a multidisciplinary discussion with the heart team, consisting of cardiovascular surgery, interventional cardiology, and vascular surgery, a percutaneous approach was chosen. He underwent successful multivessel percutaneous coronary intervention followed by fistula embolization.

Project description:Background:Ischaemic chest pain can be originated by different causes. Among all, coronary fistulas are rarely the reason. Such entities are usually asymptomatic and can be diagnosed by echocardiography or coronary angiography. In an even rarer scenario, coronary fistulas might dilate and form an aneurysm. Case summary:We report the case of a 62-year-old patient who was initially referred to the emergency department for stable angina. Coronary angiography and computed tomography scan showed a giant aneurysm relating to a coronary fistula with a course from the circumflex coronary artery to the superior vena cava. The aneurysm was critically compressing the left anterior descending coronary artery. It was confirmed and resolved by surgery. Discussion:Giant aneurysms of a coronary fistula are very uncommon entities. We describe a rare case of angina caused by extrinsic compression of the left anterior descending artery from a giant aneurysm of a coronary fistula.

Project description:Left ventricular to left atrial fi stula is a very uncommon finding. Most of the cases are secondary to surgical procedures or paravalvular infectious process. The present case depicted an unusual regurgitation (apart from transmitral MR) through LV-LA fistula causing deterioration of the patient's symptoms.

Project description:BackgroundIgG4-related disease (IgG4-RD) is a chronic fibroinflammatory condition with multiple-organ involvement. Rupture of coronary artery aneurysms (CAAs) in IgG4-RD is rare.Case summaryA 65-year-old man with IgG4-RD has suffered from recurrent episodes of arterial aneurysms since 2003. He presented with chest pain and hypotension caused by localized cardiac tamponade at right ventricle free wall due to the rupture of coronary artery aneurysm (CAA) of left anterior descending artery (LAD). An urgent LAD aneurysm repaired with bovine pericardium and obliterated aneurysmal sac with cryo-acrylate glue was done together with coronary artery bypass grafting (CABG) using saphenous vein graft (SVG) to LAD and SVG to posterior descending artery. Three-month after surgery, the follow-up coronary computed tomography angiography (CCTA) revealed a growing in size of LAD and the second obtuse marginal (OM) branch aneurysm. Heart team discussion agreed to schedule the patient for double coil embolization to LAD and second OM aneurysm under intravascular ultrasound guidance. Both aneurysms were successfully obliterated with vascular coils. Two-week follow-up coronary angiogram showed complete occlusion of LAD aneurysm and near occlusion of the second OM branch aneurysm.DiscussionCoronary artery aneurysm rupture is a life-threatening condition that required prompt detection and treatments. In IgG4-RD patients, acute cardiac tamponade suggesting the rupture of CAA. Coil embolization is an alternative treatment in patients who suffered from recurrent CAA after surgical repair. Serial CCTA is important for early detection of aneurysm in IgG4-RD patients who had vascular involvement.

Project description:Background: Single coronary ostium concomitant with coronary artery fistula is a very rare congenital anomaly. Apart from that, the combination of a closed loop of the coronary artery has never been reported. Case presentation: Herein, we present a 7-year-old girl diagnosed as single left coronary ostium with a giant coronary trunk, coronary artery to right ventricle fistula, and coronary artery ring. The coronary fistula was surgically ligated with off-pump strategy and the patient discharged on postoperative day 5 and free of symptoms during the 3 years of follow-up. Conclusion: To our knowledge, the presented congenital coronary anomaly is the first to be reported in the literature with the name of congenital coronary artery ring with single left coronary ostium and fistula.
