BACKGROUND: The presence of a fourth aortic valve cusp (quadricupsid aortic valve) is a rare congenital malformation and is often accompanied by other anomalies of the adjacent cardiovascular structures. Among these concomitant anomalies, simultaneous association of both a single coronary ostium and aneurysmal ascending aortic dilation in combination with the quadricupsid aortic valve has not been reported yet. CASE PRESENTATION: We experienced the case of a 56-year-old female patient presenting as aortic regurgitation resulted from malcoaptation of quadricupsid aortic valve...

BACKGROUND: Unroofed coronary sinus syndrome (URCSS) is a spectrum of cardiac anomalies in which part (partial type) or the entire common wall (complete type) between the coronary sinus (CS) and left atrium is absent. It is commonly associated with a persistent left superior vena cava (PLSVC). The PLSVC can even anomalously connect to the left atrium in complete type anomaly. URCSS has been reported to be associated with delayed diagnosis and life-threatening cerebral injury. The purpose of the present study was to review our experience with surgical correction of this often-concealed malformation and discuss methods for reducing diagnostic omission...

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...

INTRODUCTION: A association between partial anomalous pulmonary venous connection (PAPVC) and systemic venous anomalies has been described in the literature, but the true incidence is yet to be elucidated. At our institution, we sought to find the incidence of a persistent left superior vena cava (PLSVC) in patients undergoing an operation for PAPVC. METHODS: A retrospective review of all pediatric and adult patients with PAPVC who underwent surgical repair from February 2006 to February 2016...

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...

REVIEW
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...

Coronary artery anomalies, particularly anomalous aortic origin of a coronary artery with an interarterial course, are associated with sudden cardiac arrest or death in the young. There is paucity of data on risk stratification and longitudinal follow up is lacking in these patients. Collaboration and sharing of data among specialized centers might shed much needed light in this complex problem.

OBJECTIVE: The diagnosis of anomalous connections of the coronary arteries (ANOCOR) requires an appropriate identification for the management of the patients involved. We studied the observer variability in the description and classification of ANOCOR between a nonexpert group of physicians and a group of expert physicians, using the ANOCOR cohort. PATIENTS AND DESIGN: Consecutive patients identified by 71 referring cardiologists were included in the ANOCOR cohort...

Sinus of Valsalva aneurysm (SVA) is a rare cardiac anomaly, which mostly occurs in the right or noncoronary sinus of Valsalva. Left sinus of Valsava is infrequent. Unruptured SVAs are usually asymptomatic, and the diagnosis of unruptured SVA is usually accidental. A giant unruptured SVA may compress the coronary artery and cause myocardial infarction. Here, we report a rare case of a 50-year-old patient with unruptured giant left SVA causing occlusion of the left anterior descending coronary artery, which was successfully managed with our apparently unique surgical procedure...

There has been tremendous growth in the population of adults with congenital heart disease (CHD) over the last few decades because of advances in medical care. Whereas some cases are cured during childhood, most patients instead undergo palliation, which leaves them at risk for late complications. Lifelong clinical follow-up involving serial multimodality imaging is helpful to monitor and guide the treatment of late complications. Imaging of these individuals is challenging because of their unique anatomy and therefore requires careful consideration on a case-by-case basis...

Sudden cardiac death (SCD), particularly in the young athlete, is a rare though devastating event for families, institutions, and communities at large. It can also affect the nonathlete and occur at rest, although most commonly associated with exercise activities and/or sports participation. Common causes of SCD include cardiomyopathies, particularly hypertrophic cardiomyopathy in the United States, congenital coronary artery anomalies, channelopathies, among others. This report will explore an overview of the prevalence and causes of SCD in the young...
