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...

BACKGROUND: Coronary arteriovenous fistula is a rare congenital or acquired abnormal connection between a coronary artery and any of the great vessels or any of the heart chambers. Most of them are diagnosed during routine coronary angiography. CASE REPORT: This case report illustrates a successful surgical ligating of multiple right coronary artery and circumflex artery fistulas to coronary sinus. CONCLUSION: According to our experience and literature review, it can be concluded that to prevent potential complications in various cases of coronary arteriovenous fistula, early surgical management, just after their condition has been diagnosed, is the best choice...

Acquired coronary diseases include aneurysms, fistulae, dissections, and stenosis. Aneurysms may occur secondarily to Kawasaki disease, a childhood vasculitis, the prognosis of which depends on the coronary involvement, or they may be degenerative, infectious, inflammatory, or traumatic in origin. Fistulae develop between the coronary arterial system and a pulmonary or bronchial artery, or cardiac cavity. Dissections may occur spontaneously or may be post-traumatic. These coronary abnormalities may be found incidentally or may present as complications, infarction or rupture...

In this study, we aimed to evaluate whether patients with left to right shunt coronary artery fistula (LRSCAF) are predisposed to developing pulmonary hypertension and right ventricular dysfunction compared with healthy individuals. The value of cardiac CT findings in determining the necessity of intervention for these patients was investigated. We retrospectively studied 19 patients with LRSCAF and 19 healthy patients. Several parameters were observed on cardiac CT by two radiologists, including pulmonary trunk diameter (PA diameter), right ventricular diameter (RVD), left ventricular diameter (LVD), RVD/LVD ratio, septal bowing and CT score of right ventricular dysfunction (CSRVD)...

We report two cases in which congenital and acquired fistulae (CAFs) have been successfully closed by using the Amplatzer Ductal Occluder (ADO) II AS in children. Because of the flexibility, small profile and short length of ADO II AS, this device proved to be an excellent option in case of tortuous and short CAFs with coronary branches next to the fistulous orifice. © 2015 Wiley Periodicals, Inc.

BACKGROUND/AIMS: Factor V Leiden heterozygosity occurs in 3-8% of the general European and US populations. Activated protein C resistance (APC-R)--a non-molecular laboratory test--can efficiently demonstrate the presence of this mutation and can be performed on most coagulation analyzers. On the other hand, fistula or graft thrombosis is a common and costly complication in hemodialysis patients. Our aim was to establish the value of APC-R determination in hemodialysis patients by assessing the risk of access thrombosis in patients with increased APC-R...

BACKGROUND: Coronary arteriovenous fistulas (CAVFs) are direct connections from one or more coronary arteries to cardiac chambers or a large vessel. They are mostly of congenital origin. The aim of this study was to describe clinical presentation and also delineate the course and management of CAVF. METHODS: Clinical data, chest x-rays, echocardiographic and angiographic evaluation of 40 patients with congenital CAVF during 1990 to 2008 were reviewed retrospectively...

BACKGROUND/PURPOSE: To investigate mid- to long-term outcomes in children with coronary artery fistula (CAF). METHODS: We retrospectively reviewed the medical records of patients seen between September 1996 and August 2011. We enrolled those diagnosed with CAF via echocardiography (Philips SONOS 7500 system and Philips IE33) or angiography. The mean follow time was 42.58 ± 3.4 months (range, 1-166 months). For comparative purposes, participants were grouped as acquired versus congenital, and symptomatic versus asymptomatic...

Coronary artery fistulas (CAF) are a rare cardiac anomaly that can be either congenital or acquired. CAFs have clinical significance because of complications such as dyspnea on exertion, congestive heart failure, and cardiac tamponade. The literature also contains case reports of CAF presenting as bacterial endocarditis. We describe a 31-year-old man who presented with native valve infective endocarditis related to an unusual form of a CAF between the circumflex coronary artery and left ventricle. He also had giant coronary arteries, which were imaged with computed tomography angiography and transesophageal echocardiography...

Coronary artery fistulae are rare congenital or acquired connections between the coronary vessels and the cardiac chambers or other vascular structures. We report a case of a woman with mitral valve endocarditis and multiple pulmonary septic emboli. Transesophageal echocardiography revealed a tortuous coronary fistula as the pathway for the septic emboli. The fistula, which originated from the right coronary artery to the right atrium, was visualized using different imaging modalities.

Coronary-cameral fistula is an abnormal fistulous communication between a coronary artery and a cardiac chamber. Significant fistulae require closure either percutaneously or surgically to avoid any complications. We describe the case of a 19-year-old male patient with tetralogy of Fallot, who presented with a complex coronary-cameral fistula, which precluded percutaneous occlusion. By means of a hybrid approach, the fistula was easily located and closed surgically. Where surgical correction of such fistulae is warranted in the setting of other cardiac defects, a hybrid approach to isolate the fistula followed by surgical intervention will reduce operative time, thereby potentially lowering perioperative complications...

Spinal dural arteriovenous fistula (dAVF) is an acquired abnormal arterial-to-venous connection within the spinal dura with a wide range of clinical presentations and natural history. Spinal dAVF occurs when a radicular artery makes a direct anomalous shunt with a radicular vein within the dura of the nerve root sleeve. Spinal dAVFs are the most common vascular malformation of the spine. The authors present a patient who presented with sudden temporary lower extremity weakness secondary to an L-1 spinal dAVF...

BACKGROUND: Pulmonary arteries are not just affected by thrombus. Congenital and acquired conditions can also involve the pulmonary arteries. An awareness of these conditions is important for the radiologist interpreting chest computed tomography (CT). METHODS: The anatomy of the pulmonary arteries was reviewed. CT and magnetic resonance (MR) acquisition protocols for imaging the pulmonary arteries were discussed. The imaging appearances of congenital and acquired anomalies involving the pulmonary arteries, using CT and other modalities, were presented...

Coronary artery fistulae are characterized by communications between a coronary artery and a cardiac chamber or another vascular structure. They are usually congenital, but acquired forms may occur. Most patients are usually asymptomatic. However, some studies have emphasized that the incidence of symptoms and complications increases with age, particularly after the age of 20 (Liberthson et al. 1979, Hong et al. 2004). We aimed to present a very rare form of fistula originating from the first diagonal artery and connecting into the left ventricle...

A 62-year-old woman with Takayasu arteritis and 2 prior aortic valve replacements, was admitted with unstable angina. Computed tomographic angiography showed a newly developed right coronary artery-to-right bronchial artery fistula. Because of dense aortic calcification, catheter embolization was undertaken, which was successful. We believe the acquired coronary artery fistula developed after her uneventful second aortic valve surgery, due to inevitable trauma to the mediastinum and ascending aorta, and partly due to her underlying Takayasu arteritis...

Acquired coronary artery fistulas (CCFs) are infrequently detected during conventional coronary angiography. To delineate the characteristics of congenital (first part) and acquired (second part) CCFs in adults, a PubMed search was conducted for papers dealing with congenital or acquired CCFs. None of the publications describing patients with coronary-vascular fistulas were included. Papers dealing with pediatric subjects were excluded. From the world literature, a total of 243 adult patients were selected who had congenital (n = 159/243, 65%) and acquired (n = 84/243, 35%) CCFs...
