AIMS: Although anomalous origin of left (AOLCA) and right coronary artery (AORCA) from the wrong sinus may cause sudden death (SD) in athletes, early diagnosis and management of these anomalies are still challenging. We analysed clinical/instrumental profiles of athletes identified with AOLCA/AORCA focusing our attention on diagnosis, management and follow-up. METHODS AND RESULTS: We report 23 athletes (17 males, mean age 27±17yrs.), 6 with AOLCA and 17 with AORCA...

RATIONALE: High take-off of the coronary arteries is a rare cardiac anatomic anomaly, which may occur independently or with other congenital heart defects. In the clinical setting, it is noteworthy as a cause of sudden cardiac death. Further, it is vital to identify such anomalies to avoid intraoperative catastrophes in surgeries for congenital heart defects. PATIENT CONCERNS: A II/6 systolic heart murmur on physical examination was incidentally found in a 9-year-old boy; he was confirmed to have a secundum-type atrial septal defect on echocardiography...

The pulmonary veins carry oxygenated blood from the lungs to the heart, but their importance to the radiologist extends far beyond this seemingly straightforward function. The anatomy of the pulmonary veins is variable among patients, with several noteworthy variant and anomalous patterns, including supernumerary pulmonary veins, a common ostium, anomalous pulmonary venous return, and levoatriocardinal veins. Differences in pulmonary vein anatomy and the presence of variant or anomalous anatomy can be of critical importance, especially for preoperative planning of pulmonary and cardiac surgery...

BACKGROUND: The palmar arches serve as the most important conduits for digital blood supply, and incompleteness may lead to digital ischemia when the radial artery becomes obstructed after cardiac catheterization. The rate of palmar arch incompleteness and the clinical consequences after transradial access are currently unknown. METHODS AND RESULTS: The vascular anatomy of the hand was documented by angiography in 234 patients undergoing transradial cardiac catheterization...

The aim of this pictorial review is to describe the technical advances achieved through the application of 4-dimensional (4D) ultrasound using spatiotemporal image correlation (STIC) over conventional 2-dimensional ultrasound in the prenatal detection of congenital heart disease (CHD). Spatiotemporal image correlation is a volume imaging technique that simplifies fetal heart studies while providing more diagnostic information than is typically available from traditional 2-dimensional studies. Four-dimensional software allows the study of cardiac anatomy and function during a single cardiac cycle and has greatly contributed to diagnostic enhancement of CHD...

Two domestic shorthair cats, a 6-month-old castrated male and a 7-month-old intact female, were diagnosed with complex congenital heart disease. Transthoracic echocardiography in both cats revealed a dilated arterial trunk overriding the interventricular septum with a large ventricular septal defect. The pulmonary trunk and branch pulmonary arteries were not visible using standard echocardiographic views in either cat. The differential diagnosis for both cats included truncus arteriosus communis vs. pulmonary atresia with ventricular septal defect...

Cardiac magnetic resonance (CMR) is a non-invasive, non-ionizing, diagnostic technique that uses magnetic fields, radio waves and field gradients to generate images with high spatial and temporal resolution. After administration of contrast media (e.g., gadolinium chelate), it is also possible to acquire late images, which make possible the identification and quantification of myocardial areas with scar/fibrosis (late gadolinium enhancement, LGE). CMR is currently a useful instrument in clinical cardiovascular practice for the assessment of several pathological conditions, including ischemic and non-ischemic cardiomyopathies and congenital heart disease...

There has not been much progress in the development of transcatheter tricuspid valves to treat tricuspid regurgitation because of the difficulty in anchoring a stented valve onto the complex tricuspid annulus. Hence, the concept of heterotopic implantation of the transcatheter tricuspid valve onto the cavo-atrial junction was proposed. However, to date there has been no detailed in vitro investigation of the hemodynamic performance of this new device. The study utilises both 2-D and 3-D particle image velocimetry (PIV) to interrogate the flow patterns in the vicinity of the extra-cardiac tricuspid valves in an in vitro physiological flow loop, specifically at four measurement locations in the cavo-atrial anatomy...

Women with twin or higher-order pregnancies will typically have more ultrasound examinations than women with a singleton pregnancy. Most women will have at minimum a first trimester scan, a nuchal translucency evaluation scan, fetal anatomy scan at 18 to 22 weeks, and one or more scans in the third trimester to evaluate growth. Multiple gestations are at higher risk for preterm delivery, congenital anomalies, fetal growth restriction, placenta previa, vasa previa, and velamentous cord insertion. Chorionicity and amnionicity should be determined as early as possible when a twin pregnancy is identified to permit triage of the monochorionic group into a closer surveillance model...

Umberto Barbero, Siew Yen Ho
The left atrial appendage (LAA) has received increasing attention in recent years because of thrombi formation in patients with atrial fibrillation, which increases the risk of stroke. In patients who have contraindications for long-term oral anticoagulation therapy, percutaneous procedures are used to occlude the LAA and there are now several devices available for implantation, both endocardially and epicardially. Despite the high-resolution imaging techniques on hand today, limitations remain in providing information about wall thickness and neighboring structures; therefore, in-depth knowledge of the normal atrial anatomy is mandatory when considering such interventions...

Cardiovascular disease is the most prevalent chronic medical condition in patients treated in a dental setting. Therefore, dental practitioners must have a sound understanding of cardiovascular anatomy and physiology. Dentists also should be equipped to perform an effective preoperative cardiovascular examination and determine when medical consultation is necessary in higher risk patients. This article provides an overview of cardiovascular anatomy and physiology and discusses evaluation of cardiac risk factors with the aim of enabling dentists to effectively assess patients for potential cardiovascular events, thereby avoiding cardiovascular emergencies in the dental setting...

BACKGROUND: Coronary sinus thrombosis is a rare phenomenon. When identified, it most often is a complication of infective endocarditis or procedural intervention. We present an unusual and unreported case of spontaneous coronary sinus thrombosis as embolic sequela of an intra-abdominal infectious process. CASE PRESENTATION: We report a case of a 61-year-old white woman with a history of end-stage renal disease on hemodialysis, paroxysmal atrial fibrillation not on long-term systemic anticoagulation, and history of recurrent diverticulitis that presented with acute onset abdominal pain and nausea...

Atrial septal defects (ASDs) are common immediately after percutaneous mitral commissurotomy (PMC). They are usually small, hemodynamically insignificant, and tend to decrease or disappear within 6 to 12 months. Herein, a case is described of persistent ASD in a patient with mitral valve stenosis who had undergone successful PMC three years previously. The patient had signs and symptoms of right heart failure and severe tricuspid regurgitation (TR) with borderline right ventricular systolic function on echocardiography, in addition to the ASD...

The field of paediatric ventricular assist device (VAD) support is growing rapidly. Among paediatric patients, those with complex congenital heart disease represent a challenging population for VAD support. This report describes a patient with a remote history of an arterial switch operation for d -transposition of the great arteries who developed ischaemic cardiomyopathy necessitating centrifugal-flow VAD support as a bridge to cardiac transplantation. Because of the unique anatomy and the complicated vascular situation, implantation of the centrifugal-flow VAD and subsequent explantation for cardiac transplantation required modifications to the standard surgical approach...

Atypical anatomy may be encountered unexpectedly and undiagnosed in clinical practice, and this is especially important during the performance of interventional procedures such as transvenous implantation of cardiac electronic devices. The body of the first rib can be absent. If this not noticed, pneumo-/haemothroax may be induced during subclavian vein puncture as the needle may enter the first intercostal space rather than the costo-clavicular angle. The cephalic vein may pursue a supraclavicular course, the axillary vein may drain into an intercostal vein rather than the axillary vein, and the entire length of the axillary-subclavian-brachio-cephalic vein may be absent...

This article reminisces about the life and key scientific achievements of Jan Evangelista Purkinje (1787-1869), a versatile 19th century Czech pioneer of modern experimental physiology. In 1804, after completing senior high school, Purkinje joined the Piarist monk order, but, after a 3-yr novitiate, he gave up the religious calling "to deal more freely with science." In 1818, he earned a Medical Doctor degree from Prague University by defending a dissertation on intraocular phenomena observed in oneself. In 1823, Purkinje became a Physiology and Pathology professor at the Prussian Medical University in Breslau, where he innovated the traditional teaching methods of physiology...

Cardiovascular disease is the leading cause of death among women in the United States. Obstetrician-gynecologists often are the sole health care providers for otherwise healthy women. Therefore, they must be aware of risk factors, signs, and symptoms of cardiovascular disease and be prepared to recognize and treat this condition in patients as well as provide referrals when specialized care is indicated. Women with cardiac problems typically present with chest discomfort; however, they also are more likely than healthy women to present with other common symptoms, such as shortness of breath, back pain, jaw pain, or nausea and vomiting...
