Coronary fistula

Vivekanand Rajendran, Krishnaswamy Sundararajan, Alice Sawka
Aortocaval fistulas (ACFs) are rare with varied etiologies. Symptoms can be acute or delayed with predominant manifestations being high output cardiac failure. Acute coronary syndrome due to ACF has not been widely reported. We present a case of a 68-year-old male who presented with signs and symptoms suggestive of acute coronary syndrome. This was confirmed by electrocardiogram changes and a rise in cardiac enzymes. A large abdominal aortic aneurysm was diagnosed initially by imaging without evidence of leak or rupture...

Coronary artery fistula is an exceedingly uncommon congenital disorder characterized by fistulous communication of a coronary artery with asystemic or pulmonary vessel or a heart chamber. Small fistulas are asymptomatic and benign while large fistulas present in a variety of ways like heart failure, arrhythmias or endocarditis. We report here a rare case of eight years old girl who presented to us with history of shortness of breath and palpitation. Her echocardiography revealed a moderately large right coronary artery fistula that was opening into right ventricle...

Left atrial myxoma is the common benign tumor of heart. Coronary arteries may supply these tumor. Considering the vascular nature of the tumor, acquired coronary cameral fistula(CCF) can be a possibility postexcision of the left atrial myxoma. Here, we discuss a case of 53-year-old female patient, who developed acquired CCF, following excision of the tumor and the role of transesophageal echocardiography intraoperatively in diagnosis.

Coronary artery fistula (CAF) is a rare, abnormal connection between one or more coronary arteries and a cardiac chamber, or great vessel.We describe the case of a male patient with worsening effort angina referred for coronary angiography. The examination revealed the presence of a CAF between the proximal left anterior descending (LAD) and pulmonary arteries, with mid LAD subocclusive stenosis. Ad hoc PCI with stenting was performed in the mid LAD, followed by CAF embolization with coils and plugs. Angiography and computed tomography scan at follow-up showed complete CAF occlusion, stent patency, and normal flow reserve of the LAD...

This case report describes a coronary bypass surgery case in which cardioplegic arrest was impossible due to an aortacoronary fistula that was visualized using 3-dimensional computer tomography (CT) angiography postoperatively. Aortacoronary fistulas are protective in coronary artery disease but can severely complicate cardiac surgery and might require CT imaging in the preoperative workup.

Coronary artery fistulae (CAF) are rare anomalies with controversial management strategies. The two main treatment options include either surgical repair or catheter embolization. Herein, we report successful treatment of a complex right coronary artery (RCA) to coronary sinus (CS) fistula using a less conventional approach: multiple coronary artery bypass grafting.

BACKGROUND A coronary artery-left ventricular fistula is an anomalous communication between the coronary arteries and the cardiac chambers and is a rare congenital coronary anomaly that is often small and asymptomatic. Takotsubo cardiomyopathy, on the other hand, is a syndrome characterized by transient regional systolic dysfunction of the left ventricle, mimicking myocardial infarction, but in the absence of angiographic evidence of obstructive coronary artery disease or acute plaque rupture. We present the case of an elderly woman who presented with Takotsubo cardiomyopathy and who was incidentally discovered to have an associated coronary artery-left ventricular fistula...

We report a case of a 60-year-old man with a history of angina on exertion (New York Heart Association Class II) who was found to have mid-cavitary obstructive hypertrophic cardiomyopathy on two-dimensional echocardiography and whose coronary angiogram showed right coronary artery-left ventricular fistula, with no significant coronary atherosclerosis suggestive of ischaemic heart disease. The patient was started on beta-blocker therapy, and on follow-up his angina improved. The patient had a benign course and did not have any progressive heart failure or acute coronary syndrome on follow-up...

A 75-year-old woman with chest discomfort and a continuous murmur was admitted to our hospital. During noninvasive examination, computed tomography angiography showed a coronary artery-pulmonary artery fistula with double giant coronary aneurysms (one was 42 mm× 32 mm× 32 mm, and the other was 25 mm× 20 mm× 17 mm) arising from the proximal part of the left anterior descending (LAD) artery. Stress myocardial scintigraphy showed ischemia at the LAD area. Given her frailty, the heart team, including cardiac surgeons, judged that surgical treatment would be difficult...

Prenatal diagnosis of a huge coronary artery fistula between the left coronary artery and the right ventricle was made by Doppler echocardiography at 22 weeks of gestation. Progression of the dilated fistula was monitored throughout pregnancy. The size of the fistula increased enormously up to 11 mm. Death occurred at birth. Monitoring of these fetuses is essential as severe complications can occur during pregnancy or at birth.

BACKGROUND: To evaluate the ability of low radiation dose dual-source computed tomography (DSCT) to depict the features of morphological univentricular heart and to define accuracy by comparing findings with surgery. METHODS: Low radiation dose dual-source cardiac computed tomography (CCT) of 33 cases of functional univentricular heart preliminary diagnosis by echocardiography compared with the results of surgery were retrospectively analyzed (aged 1 day to 4 years, median 5 months)...

Giant coronary artery aneurysms (GCCAA) are extremely rare entities, and of the circumflex artery we are aware of only 13 case reports. We therefore provide this case report to add evidence of the natural history and pathophysiology and describe successful surgical treatment of the condition.

Coronary artery fistula (CAF) is a rare congenital anomaly, which is most commonly asymptomatic. In symptomatic cases, aneurysms can occur with complications of thromboembolic events. This report describes a rare case of CAF presenting with complications of inferior acute myocardial infarction and thrombus formation in the right ventricle.

We present two cases where fractional flow reserve (FFR) was utilised to guide management of coronary artery fistula (CAF), an approach advocated in recent case studies. CAF is a coronary anomaly that may present with a variety of syndromes though is frequently asymptomatic. When to exclude the fistula (surgically or percutaneously) is not always clear. A way to quantify if the fistula is physiologically meaningful would be advantageous. Our findings suggest FFR may only be assessing the concomitant epicardial coronary artery disease (CAD) rather than the degree of coronary steal and its routine use in this setting is not supported...

BACKGROUND: Femoral arterial access (FAA) during diagnostic coronary angiography (CAG) and percutaneous coronary interventions (PCI) are associated with several vascular complications (VC). VC rate in our experience a decade ago was 3.02% and higher in women (4.7% in women, and 1.67% in men, p < 0.0006), with an OR of 2.81 (95% CI: 1.51-5.22). METHODS: Patients who underwent CAG and PCI utilizing FAA (n = 2617) were separated into Period 1 (2005 to 2008; 1970 patients; Male 1045; Female 925) and Period 2 (2016-2017; 647 patients; Male 357; Female 290)...

Coronary artery fistula is a rare anomalous connection between a coronary artery and a cardiac chamber or major vessel. Here we present the case of a 36-year-old woman who presented with sharp, substernal chest pain, dyspnea, and dizziness. A fistula between her left anterior descending artery and pulmonary trunk was found. Herein, we describe our approach and review the epidemiology, pathophysiology, diagnosis, and treatment options.
