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...

Congenital coronary artery fistula is an uncommon anomaly. Transcatheter coil embolization or Amplatzer vascular plug device closure of fistula is often done in symptomatic patients with safe accessibility to the feeding coronary artery. Embolization of Amplatzer vascular plug device is rare. We report an 11-year-old male child who presented to us with increasing shortness of breath for 7 years. He had a history of Amplatzer vascular plug device closure of right coronary-cameral fistula 8 years back. Echocardiography demonstrated a dilated aneurysmal right coronary artery with turbulent jet entering into the right ventricle (RV) and device embolized into the left pulmonary artery (LPA)...

BACKGROUND: An aberrant origin of the left coronary artery (LCA) from the right coronary cusp (RCC) is an extremely rare congenital anomaly. We here report on successful percutaneous coronary intervention (PCI) in a patient presenting with acute coronary syndrome and an aberrant origin of the LCA from the RCC. CASE PRESENTATION: A 50-year-old man presented at our emergency department with recurrent resting chest pain. Following unsuccessful attempts at visualizing the left coronary artery using Judkins left and Amplatz catheters, an aortogram using a pigtail catheter suggested anomalous left coronary artery origin and showed a significant occlusive lesion at proximal left anterior descending artery...

Primary coronary sinus tumors are extremely rare. Herein, we present a case of a pregnant woman with a primary myxoma in the coronary sinus (CS), which was diagnosed by echocardiography and computed tomography. We reviewed the literature and found two other primary CS tumors. We summarized the gender, ages, symptoms, diagnostic methods, associated anomalies, treatments, histologic findings, and outcomes of the 3 cases. Dyspnea was a common symptom of all 3 patients. Diagnostic methods included echocardiography, computed tomography, magnetic resonance imaging, and coronary angiography...

Single coronary artery is an extremely rare congenital coronary anomaly in which the entire coronary arterial system arises from a solitary ostium. The Lipton's classification is used for single coronary artery anomalies. Herein, we present a 72-year-old woman with single coronary artery anomaly admitted with atypical chest pain. Coronary angiography and multidetector computed tomography coronary angiography findings were shared.

BACKGROUND: Full iterative reconstruction algorithm is available, but its diagnostic quality in pediatric cardiac CT is unknown. OBJECTIVE: To compare the imaging quality of two algorithms, full and hybrid iterative reconstruction, in pediatric cardiac CT. MATERIALS AND METHODS: We included 49 children with congenital cardiac anomalies who underwent cardiac CT. We compared quality of images reconstructed using the two algorithms (full and hybrid iterative reconstruction) based on a 3-point scale for the delineation of the following anatomical structures: atrial septum, ventricular septum, right atrium, right ventricle, left atrium, left ventricle, main pulmonary artery, ascending aorta, aortic arch including the patent ductus arteriosus, descending aorta, right coronary artery and left main trunk...

A 7-year-old girl with severe mitral regurgitation and pulmonary artery hypertension with good ventricular function was planned for mitral valve repair, but was subsequently diagnosed to have anomalous left coronary artery from pulmonary artery. We describe the pitfalls in the diagnosis of this rare anomaly, particularly in the presence of severe pulmonary artery hypertension and absence of circumstantial evidence of coronary steal and ventricular dysfunction.

Anomalous coronary artery origin is a rare, but important cause of cardiac ischemia, particularly in younger patients. These anomalies of origin can be divided into two groups, benign or malignant, based on their propensity to cause ischemia or sudden death. Symptomatic, or malignant coronary artery anomalies are usually described with respect to anomalous origins of the right coronary artery or left main coronary artery. We present a unique case of a previously unreported entity, an anomalous left circumflex coronary artery causing ischemia...

Anomalous aortic origin of a coronary artery (AAOCA) occurs when both coronary arteries arise from the same aortic sinus from a single ostium or two separate ostia. While most coronary anomalies are benign, the two most common subtypes that predispose to sudden cardiac death in the young are interarterial anomalous right coronary artery and interarterial anomalous left coronary artery. Practitioners face many challenges with AAOCA. Diagnosing patients may be difficult because children and adolescents are often asymptomatic and first presentation may be sudden death or sudden cardiac arrest...

Anomalous origin of the left coronary artery from the right pulmonary artery in single ventricles is a very rare congenital anomaly. Failure to recognise it preoperatively may lead to adverse outcomes, including death. We report the case of a neonate with a univentricular heart in the form of a double-outlet right ventricle, mitral atresia with discrete coarctation of the aorta, and an incidental intraoperative finding of an anomalous origin of the left coronary artery from the right pulmonary artery. The patient underwent a successful repair with an uneventful postoperative course...

BACKGROUND: Coronary anomalies are frequently present in children with transposition of the great arteries (TGA). Such anomalies significantly increase the complexity of arterial switch operations and may have an effect on postoperative outcomes. In this study, we aimed to assess the frequency of coronary anomalies in children with TGA and describe their effect on postoperative outcomes. METHODS: All patients with TGA who underwent an arterial switch operation between 1991 and 2015 were consecutively enrolled in this study...

Jamshed J Dalal, Sundeep Mishra
The combined and relative contribution of glucose and fatty acid oxidation generates myocardial energy, which regulates the cardiac function and efficiency. Any dysregulation in this metabolic homeostasis can adversely affect the function of heart and contribute to cardiac conditions such as angina and heart failure. Metabolic agents ameliorate this internal metabolic anomaly, by shifting the energy production pathway from free fatty acids to glucose, resulting in a better performance of the heart. Metabolic therapy is relatively a new modality, which functions through optimization of cardiac substrate metabolism...
