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...

Central venous catheters are placed in approximately five million patients annually in the US. The preferred site of insertion is one with fewer risks and easier access. Although the right internal jugular vein is preferred, on occasion, the left internal jugular may have to be accessed. A patient was admitted for septic shock, cerebrovascular accident, and non-ST-segment elevation myocardial infarction. A central venous line was needed for antibiotic and vasopressor administration. Due to trauma from a fall to the right side and previously failed catheterization attempts at the left subclavian and femoral veins, the left internal jugular vein was accessed...

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...

Sinus of Valsalva aneurysm is a rare cardiac anomaly with wide spectrum of clinical presentation ranging from asymptomatic state to dreadful complications due to compression of vital surrounding structures or aortic dissection. There are only few reported cases of sinus of Valsalva aneurysm presented with cardiac arrhythmias including complete heart block. We herein, present a case of a 50 year male who presented with complete heart block. A large noncoronary sinus of Valsalva aneurysm compressing the surrounding atrioventricular junctional tissue was detected incidentally during echocardiographic study, which was considered to be the cause of patient's complete heart block...

Anomalous coronary artery from the opposite sinus is a rare congenital anomaly that can present with symptoms similar to coronary artery disease, and sudden cardiac death. Management of anomalous coronary artery from the opposite sinus varies; however, current guidelines suggest surgery in symptomatic patients. Our patient is a middle-aged male with a history of coronary artery disease and status post coronary artery bypass graft. He presented with complaints of vague chest pain. After a positive stress test, he was sent to the catheterization suite...

OBJECTIVE: Surgical coronary revascularisation in children with congenital heart disease (CHD) is a rare event for which limited information is available. In this study, we review the indications and outcomes of surgical coronary revascularisation from the Pediatric Cardiac Care Consortium, a large US-based multicentre registry of interventions for CHD. METHODS: This is a retrospective cohort study of children (<18 years old) with CHD who underwent surgical coronary revascularisation between 1982 and 2011...

In this case series, we delve into the database of medicolegal cases of the Forensic Pathology Department at Hamilton Health Sciences in Hamilton Ontario from the last 20 years (1996-2017), and review cases of sudden cardiac death due to coronary artery abnormalities. We found 17 cases that fit the criteria, which gave us an incidence of 1.34 per 1000 cases. These cases were further audited for age, sex, type of coronary artery abnormality, symptoms before demise, circumstances of death, presence of significant atherosclerotic disease, and toxicology...

INTRODUCTION: Various anomalies in the development of the great thoracic veins of the embryo can be incidentally discovered in the normal adult. Duplication of superior vena cava (SVC) is a rare abnormality, but the most common thoracic venous congenital anomaly. Case reports-methods: We present two cases in the intensive care unit of our hospital, of asymptomatic patients who underwent an uneventful central line placement in the left subclavian vein. The track of the catheter, as shown in the X-ray, was misplaced to the left of the aorta and further investigation with computed tomography angiography confirmed a persistent left SVC...

A baby with pulmonary atresia with intact ventricular septum and hypoplastic right ventricle, with suspected right ventricle to coronary communications, was operated on for placing an aortopulmonary shunt. Postoperatively, the baby deteriorated with features of myocardial ischemia. Postmortem examination revealed anomalous origin of left coronary artery from pulmonary artery that caused significant coronary ischemia on ligation of the ductus arteriosus. Although coronary anomalies, including right ventricle dependent coronary circulation, has been well described, this is the first report of anomalous origin of coronary artery from pulmonary artery in a baby with pulmonary atresia and intact ventricular septum...

The vertebrate heart receives the blood through the cardiac inflow tract. This area has experienced profound changes along the evolution of vertebrates; changes that have a reflection in the cardiac ontogeny. The development of the inflow tract involves dynamic changes due to the progressive addition of tissue derived from the secondary heart field. The inflow tract is the site where oxygenated blood coming from lungs is received separately from the systemic return, where the cardiac pacemaker is established and where the proepicardium develops...

BACKGROUND: Mutations of α-actin gene (ACTC1) have been phenotypically related to various cardiac anomalies, including hypertrophic cardiomyopathy and dilated cardiomyopathy and left ventricular (LV) myocardial noncompaction. A novel ACTC mutation is reported as cosegregating for familial hypertrophic cardiomyopathy and LV myocardial noncompaction with transmural crypts. METHODS AND RESULTS: In an Italian family of 7 subjects, 4 aged 10 (II-1), 14 (II-2), 43 (I-4) and 46 years (I-5), presenting abnormal ECG changes, dyspnea and palpitation (II-2, I-4, and I-5), and recurrent cerebral ischemic attack (I-5), underwent 2-dimensional echo, cardiac magnetic resonance, Holter monitoring, and next-generation sequencing gene analysis...

Congenitally corrected transposition of the great arteries is a rare form of CHD. Situs inversus is a much less common variant of a congenitally corrected transposition of the great arteries. In rare cases, transposition events may be accompanied by various cardiac anomalies. However, situs inversus patients with congenitally corrected transposition, single coronary artery anomaly, and atrioventricular block together have not been reported previously. This combination of abnormalities is presented as a first in the literature...

A 75-year-old woman presented with severe tricuspid regurgitation requiring surgical repair. She had extremely rare anomalies in systemic venous return in spite of situs solitus: persistent left superior vena cava with absent right superior vena cava, infrahepatic inferior vena cava interruption, and hemiazygos continuation to a persistent left superior vena cava. These unusual systemic venous anomalies had significantly enlarged the coronary sinus, and the stretched coronary sinus orifice changed the geometry of the tricuspid annulus and triggered tricuspid regurgitation...
