Coronary arterial abnormalities are uncommon findings in children that have profound clinical implications. Although anomalies of the coronary origins are well described, there are many other disease processes that affect the coronary arteries. Immune system-mediated diseases (eg, Kawasaki disease, polyarteritis nodosa, and other vasculiditides) can result in coronary arterial aneurysms, strictures, and abnormal tapering of the vessels. Because findings at imaging are an important component of diagnosis in these diseases, the radiologist's understanding of them is essential...

BACKGROUND: Nonalcoholic fatty liver disease is rising to the growing epidemic of metabolic syndrome. Recent data suggest that this liver disease may represent a real marker of cardiovascular risk. The aim of our study was to calculate cardiovascular risk and to estimate the frequency of subclinical coronary artery disease by conducting an exercise testing. METHODS: This is a prospective study conducted over a period of one year including all patients followed for non alcoholic fatty liver disease...

The formation of a fistula between the internal mammary artery and the pulmonary vasculature (IMA-to-PV) is a rare anomaly. The etiology can be congenital; however, most recent cases have been associated with coronary artery bypass grafting, trauma, inflammatory conditions, chronic infections, or neoplasia. The knowledge base on the formation of these fistulas is derived primarily from case reports. To our knowledge, no systematic reviews or guidelines are available that provide information on how to manage these cases, and the treatment of an IMA-to-PV fistula is controversial...

Coronary artery anomalies may cause life-threatening cardiac complications; however, developmental mechanisms underpinning coronary artery formation remain ill-defined. Here we identify an angiogenic cell population for coronary artery formation in mice. Regulated by a DLL4/NOTCH1/VEGFA/VEGFR2 signaling axis, these angiogenic cells generate mature coronary arteries. The NOTCH modulator POFUT1 critically regulates this signaling axis. POFUT1 inactivation disrupts signaling events and results in excessive angiogenic cell proliferation and plexus formation, leading to anomalous coronary arteries, myocardial infarction and heart failure...

BACKGROUND: The new European guidelines on diabetes mellitus and cardiovascular diseases propose that the FINnish Diabetes RIsk SCore should be used to evaluate the risk of diabetes mellitus and that diabetes mellitus screening in coronary artery disease patients should be based on fasting glucose and HbA1c. The 2 hour oral glucose tolerance test, recommended for all pts in the previous guidelines, is now only recommended for 'inconclusive' cases. We aimed to evaluate this new strategy...

First described in 1908, anomalous origin of left coronary artery from pulmonary artery is a very rare congenital anomaly. Here, the right coronary artery is usually enlarged and has a normal origin from aorta. Numerous collaterals connect the two coronary arteries over right ventricular outflow tract or interventricular septum. It is one of the most common causes of myocardial ischaemia and infarction in children.

The diagnosis of anomalous origin of the left main coronary artery from the right coronary sinus with an interarterial course in children and adolescents is considered life-threatening and clinical guidelines recommend surgical correction. The prognostic implications of this diagnosis in adults are not clear. This anomaly may present in adults as sudden cardiac death or may be diagnosed incidentally. Treatment of this anomaly in adults should be tailored individually taking into account the clinical presentation and patient characteristics...

We present a case of rescue percutaneous coronary intervention (PCI) using right radial approach in a rare case of single coronary artery originating from the right sinus. Although these anomalies and stenosis of anomalous vessels have earlier been reported, treatment of atherosclerotic lesions by PCI has rarely been reported. There is a definite risk during PCI in patients with a single coronary ostium because dissection with the guiding catheter would result in a catastrophic event. Additionally, technical difficulties may occur due to the ostial configuration and course of the branch to be stented...

Double Right Coronary Artery (RCA) is one of the rarest congenital coronary anomalies. Although it can be regarded as a benign condition in the vast majority of cases, it has been associated with acute and life-threatening presentations, including inferior ST-segment elevation myocardial infarction (STEMI), cardiogenic shock and complete heart block, tachyarrhythmias, or even sudden death. However, the role of a double RCA in these conditions is yet to be clarified as more recent data prove no statistically significant association between prevalence of significant atherosclerosis in anomalous coronary arteries in comparison to normal coronary arteries...

Early repolarisation is a common electrocardiographic (ECG) finding characterised by J-point and ST segment elevation ≥ 0.1 mV in two or more adjacent leads. The ECG pattern of early repolarisation is relatively common in asymptomatic subjects. Early repolarisation pattern may be seen in secondary conditions such as hypothermia, autonomic nervous system disturbances, cocaine abuse, hypercalcaemia and myocardial ischaemia. We present a case of an adolescent boy with chest pain and concurrent ST-segment elevation...

Cardiac CT angiography utilized in the emergency room for triage of low-to-intermediate risk chest pain on occasion identifies unexpected abnormalities. In this case, multiple coronary anomalies existed in the same patient. Images and clinical decision making are discussed in this presentation. Coronary anomalies are being recognized with increased frequency due to increasing use of this modality in the evaluation of chest pain. The clinical implications of these findings are not always clear.

Taussig-Bing anomaly and aortic arch obstruction are two types of complex congenital cardiac malformations. Almost 50% of patients with Taussig-Bing anomaly have aortic arch obstruction. This report assesses the surgical outcomes of single-stage correction in neonates with both defects. Between November 2006 and November 2015, 39 neonates with Taussig-Bing anomaly and aortic arch obstruction (28 patients with coarctation of the aorta and 11 patients with interrupted aortic arch) underwent a one-stage arterial switch operation and aortic reconstruction...

OBJECTIVE: In patients with bicuspid aortic valve (BAV), coronary anatomy is variable. High take-off coronary arteries have been described, but data are scarce, especially when associated with complex congenital heart disease (CHD). The purpose of this study was to describe coronary patterns in these patients. METHODS: In 84 postmortem heart specimens with BAV and associated CHD, position and height of the coronary ostia were studied and related to BAV morphology...

Coronary artery fistulae are rare cardiac anomalies with a prevalence of 0.2% of all the patients undergoing coronary angiography. The majority of them are congenital and generally origin from the right coronary artery. Occasionally acquired (mostly iatrogenic) fistulae can develop. Although frequently subclinical, symptoms of angina and congestive heart failure may occur. We present an unusual well-illustrated case of a strongly dilated circumflex coronary artery with formation of two giant aneurysms and fistulous communication towards the right atrium...

Congenital coronary artery anomalies as a whole are uncommon. Abnormal origin of the left coronary artery from the pulmonary artery (ALCAPA) is probably the most common congenital coronary defect. An overwhelming majority of the patients with untreated ALCAPA do not survive to adulthood. As yet, there is no consensus on the management of adults with ALCAPA. We describe a patient with breast malignancy and incidentally detected ALCAPA; primacy was given to treatment of the oncologic condition as a first step...
