Umbilical vein anomalies are a rare congenital defect, which have been associated with absent ductus venosus, with few cases also involving a congenital diaphragmatic hernia. We describe a case of postnatal development of an anterior diaphragmatic hernia of Morgagni in a four-year-old patient diagnosed prenatally with mesocardia, absent ductus venosus with a large umbilical vein, a large secundum atrial septal defect, and patent ductus arteriosus.

Persistent left superior vena cava (LSVC) is a rare congenital anomaly. Its prevalence in the general population is 0.1 to 0.5%. LSVC is 5 times rarer when accompanied by an absence of the right superior vena cava (RSVC). We present the case of a 54-year-old man who carries a persistent LSVC without RSVC. Clinically, this patient presented a regular bradycardia at 40 per minute associated with a heart failure syndrome. The electrocardiogram diagnosed a complete atrioventricular block and transthoracic echocardiography showed dilated left heart cavities and a left ventricular ejection fraction of 50%...

The description of totally anomalous systemic venous connection is limited to case reports. In this review, we seek to clarify anatomic, physiologic, and hemodynamic aspects of this extremely rare anomaly. We also present findings of two patients in whom connection of all the systemic veins was anomalous. In the first patient, with usual atrial arrangement, all systemic veins, including the coronary sinus, were connected anomalously to the morphologically left atrium. Limited left-to-right shunt across an atrial septal defect provided the only source of blood flow to the lungs...

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.

BACKGROUND: Myocardial bridging is a common coronary anomaly, with few severe adverse events but a relevant symptom burden. Myocardial bridging treatment, however, remains uncertain because of the lack of randomized trials. MATERIAL: MEDLINE/PubMed was systematically screened for studies reporting on isolated myocardial bridging diagnosed at coronary angiography or with coronary computed tomography in patients admitted for suspected angina or with an acute coronary syndrome...

A subannular left ventricular aneurysm is very rare, and is mostly considered to be a congenital anomaly. A subannular left ventricular aneurysm is classified based on the type of its own orifice-submitral or subaortic. Subaortic left ventricular aneurysm occurs less frequently compared with a submitral type of subannular aneurysm. We hereby describe a rare case of a huge bilobed subaortic aneurysm, in which the orifice was located just below the left coronary cusp diagnosed with multimodality imaging in a child...

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...

BACKGROUND AND OBJECTIVE: The high mortality rate associated with coronary heart disease (CHD) has driven intensive research in cardiac imaging and image analysis. The advent of computed tomography angiography (CTA) has turned non-invasive diagnosis of cardiovascular anomalies into reality as calcified coronary plaques can be easily identified due to their high intensity values. However, the detection of non-calcified plaques in CTA is still a challenging problem because of lower intensity values, which are often similar to the nearby blood and muscle tissues...

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...

Transradial access has become popular and preferred approach in coronary interventions due to high success rate, low risk of complications and patients' comfort. However various anatomical variations and anomalies may pose technical challenge. Arteria lusoria is an uncommon condition which is technically challenging and may warrant cross-over to alternate access. We report a middle aged male presenting with acute coronary syndrome in which arteria lusoria was incidentally detected during right transradial coronary intervention...

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...
