Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a common coronary artery anomaly associated with high mortality and may lead to sudden death if left unrecognized and untreated. This report describes an 8-year-old female who had cardiac murmur but with no clinical symptoms. Electrocardiogram (ECG) was normal, but echocardiography made the diagnosis of ALCAPA. Digital subtraction angiography (DSA) with cardiac catheterization angiography (CAG) confirmed the diagnosis, and finally, the patient received surgery...

We report a 1-month-old infant diagnosed with an aorta-left ventricular tunnel, ventricular septal defect, and right coronary atresia with right ventricular sinusoids. The patient's anatomy and physiology did not indicate right-ventricular-dependent coronary circulation, and therefore right ventricular decompression could be performed without compromising coronary perfusion during surgical correction. A detailed understanding of the coronary anatomy is critical in managing this defect when coronary anomalies are present...

Coronary artery disease (CAD) is a major cause of death worldwide. It is significantly important to assess the coronary lesion and its pathophysiological relevance comprehensively. Coronary computed tomography angiography (CTA) or myocardial perfusion imaging alone suffers from some limitations in the evaluation of CAD. Through the integration and spatial colocalization of complementary morphological and functional information, the results of published hybrid single-photon emission computed tomography (SPECT)/CTA studies in patients with CAD are promising for detecting functionally relevant coronary artery lesion and evaluating the relationship between diseased coronary artery, coronary artery anomaly, myocardial bridging, or coronary calcification and myocardial ischemia...

Double right coronary artery is a relatively rare coronary anomaly. In this case report we aim to increase awareness of the importance of recognizing such anomaly and a brief literature review of similar cases and possible high risk features. Computed Tomography is well recognized modality to detect coronary anomaly and in our case we demonstrated this as well.

Congenital anomalies of the coronary arteries are a cause of sudden cardiac death. Of the known anatomic variants, anomalous origination of a coronary artery from an opposite sinus of Valsalva (ACAOS) remains a major clinical issue and a challenging condition to treat. Congenital coronary anomalies are likely to be under-recognized, as completing an anatomic assessment in a very large portion of the population would seem unfeasible. However, we present a case report with image of a 49 year old male presented with acute non-ST elevation ACS for which he underwent diagnostic angiography of the coronary system which revealed a common origin of both right and left main coronary artery from right sinus of Valsalva with significant obstructive lesion in the mid segment of right coronary artery...

OBJECTIVES: Aortic arch repair has been shifted from deep hypothermia plus circulatory arrest to cerebral perfusion at tepid temperatures. A step forward is a simultaneous brain-coronary perfusion, allowing beating-heart arch surgery. METHODS: A 'Y' cannula from the arterial line delivers oxygenated blood to brain and heart. The arch is repaired on a beating heart at 25°C. Intracardiac repair is performed after running cardioplegia through the root line. Fifty patients are classified into 3 groups: A, Norwood (8 neonates); B, aortic arch (14 children) and C, aortic arch plus intracardiac repair (28 patients)...

The incidence of congenital coronary artery anomalies in the general population is low. The combination of various significant coronary artery anomalies in a single patient is not very common. We describe a case of a 20-month-old child with a unique combination of congenital coronary anomalies (atresia, stenosis, fistula) which were accurately delineated by multimodal imaging and successfully managed surgically.

Coronary artery fistulas (CAFs) are abnormal communications of coronary arteries whereby venous circuits bypass the normal capillaries within the myocardium. CAFs are rare, and most affected patients are asymptomatic. However, these fistulas are the most common coronary artery anomalies that can alter coronary hemodynamic parameters. Although most CAFs are asymptomatic in young patients, symptoms and complications become more frequent with increasing age. CAFs are characterized by variable clinical manifestations that are based on the size, origin, and drainage site of the fistula...

Congenital left ventricular aneurysm or diverticulum are rare cardiac malformations described in 809 cases since the first description in 1816, being associated with other cardiac, vascular or thoraco-abdominal abnormalities in about 70%. It appears to be a developmental anomaly, starting in the 4th embryonic week. In an experimental study, targeted knockdown of cardiac troponin T in the chick was performed at day 3, after the heart tube has formed. Morpholino treatment of gene TNNT2 at this stage led to the development of left ventricular diverticula (LVD) in the primitive left ventricular wall...

Anatomically corrected malposed great arteries is an uncommon and benign entity. Basically, this occurs with ventriculoarterial concordance in which the great vessels arise parallel instead of a twisting fashion. In this manuscript, we described two cases in which the antenatal diagnosis of anatomically corrected malposition of great arteries was suspected and confirmed during the postnatal period. During the fetal life, this diagnosis remains a challenge and this condition is often misdiagnosed as the transposition of the great arteries (TGA)...

Right coronary artery (RCA) originating from the left coronary system is a subtype of single coronary artery (SCA) anomaly, and the origin of RCA as a branch from the left anterior descending artery (LAD) is a very rare variant. A 55-year-old male who had a percutaneous coronary intervention (PCI) history was hospitalized due to acute coronary syndrome. Coronary angiography revealed an aberrant RCA originating from the mid-LAD as well as stent thrombosis. A successful PCI was performed and he was discharged from the hospital three days after the PCI...

Mesocardia is an extremely rare congenital cardiac anomaly of counter clockwise rotation of the heart. We report here a case of coronary artery bypass grafting in mesocardia, which has not been described in medical literature earlier. A 52 years male suffered an anterior wall myocardial infarction. Chest X Ray, 2 D Echocardiography and computed tomography of chest confirmed the presence of mesocardia. Off pump total arterial revascularization was done. Exposure of aorta and right atrium through the standard median sternotomy is very difficult in mesocardia due to cardiac rotation and should be kept in mind in this surgery...

PurposeCongenital central hypoventilation syndrome (CCHS, OMIM 209880) is a rare autosomal dominant disorder caused by mutation in PHOX2B that manifests as a consequence of abnormal neural crest cell migration during embryogenesis. Unlike other neurocristopathies, however, its impact on the cardiovascular system has not been previously assessed. This study was an effort to characterize the association between congenital heart disease (CHD) and mutations in PHOX2B in patients with CCHS.MethodsA retrospective review of patients with CCHS in conjunction with functional analysis of PHOX2B mutations associated with CHD was performed...

Diagnosed with peripartum cardiomyopathy 8 years earlier, a 45-year-old female suffered sudden cardiac death. Following resuscitation, the patient was diagnosed with an anomalous origin of the left coronary artery from the pulmonary artery and underwent a successful coronary repair. The management of a patient with clinical features of cardiomyopathy is reviewed. Anomalous left coronary artery originating from the pulmonary artery (ALCAPA) is a rare but potentially lethal congenital anomaly affecting 1 in 300,000 live births1 ...

OBJECTIVES: Anomalous aortic origin of a coronary artery (AAOCA) from the opposite sinus of Valsalva is a rare cardiac anomaly associated with sudden cardiac death (SCD). Single-center studies describe surgical repair as safe, although medium- and long-term effects on symptoms and risk of SCD remain unknown. We sought to describe outcomes of surgical repair of AAOCA. METHODS: We reviewed institutional records for patients who underwent AAOCA repair, from 2001 to 2016, at 2 affiliated institutions...

Coronary artery fistula (CAF) is a relatively rare anatomic abnormality of the coronary arteries that afflicts 0.002% of the general population and represents 14% of all the anomalies of coronary arteries. Its clinical relevance focusses mainly on the mechanism of "coronary steal phenomenon", causing myocardial functional ischaemia even in the absence of stenosis, hence common symptoms are angina or effort dyspnoea. The suggested diagnostic approach is guided by the patient's symptoms and consists of a number of instrumental examinations like ECG, treadmill test, echocardiography, computed tomography scan, cardiac magnetic resonance and coronary angiography...

Congenital coronary artery anomalies are modifications of their origin, course or structure and its incidence varies between 0,2 and 5,6% of the general population. Although the majority is asymptomatic, they are the second leading cause of sudden cardiac death in young athletes. The aim of this study is to highlight the main anomalies with hemodynamic significance, including the anomalous origin of a coronary artery from the opposite sinus and anomalous origin of the left coronary artery from pulmonary artery...
