The case of an 11-year-old male patient with truncus arteriosus is presented. The patient has a right aortic arch, a repaired truncus arteriosus, pulmonary artery stenosis, as well as conduit stenosis, with a complex surgical plan being discussed. In order to gather additional insight into the patient's anatomy prior to the surgery and to facilitate communication with the patient's parents, a three-dimensional (3D) model of his heart and main vessels was created from computed tomography data. Feedback was collected from different stakeholders...

For left-sided postmastectomy patients requiring chest wall plus comprehensive nodal irradiation, sometimes traditional techniques such as partial wide tangents or electron/tangents combination are not feasible due to abnormal chest wall contour or heart position or unusually wide excision scar. We developed electron chest wall irradiation technique using Electron Monte Carlo (EMC) dose algorithm that will achieve heart sparing with acceptable ipsilateral lung dose, minimal contralateral lung, and breast dose...

REVIEW
Brian D Hoit
The pericardium consists of a visceral mesothelial monolayer (epicardium) that reflects over the great vessels and joins an outer, relatively inelastic fibrous parietal layer of organized collagen and elastin fibers, between which is a potential space that normally contains up to 50 mL of plasma filtrate. Although not essential for life, the pericardium serves important albeit subtle functions in the euvolemic healthy individual that become increasingly important in hypervolemic states and conditions in which the heart enlarges acutely...

The purpose of this study was to examine the histopathologic reliability of embalmed cadaveric tissue taken from the gross anatomy laboratory. Tissue samples from hearts, livers, lungs, and kidneys were collected after the medical students' dissection course was completed. All of the cadavers were embalmed in a formalin-based fixative solution. The tissue was processed, embedded in paraffin, sectioned at six micrometers, and stained with H&E. The microscope slides were evaluated by a board certified pathologist to determine whether the cellular components of the tissues were preserved at a high enough quality to allow for histopathologic diagnosis...

BACKGROUND: Patients with congenital or acquired heart defects affecting the pulmonary valve and right ventricular outflow tract (RVOT) commonly require multiple surgical interventions, resulting in significant morbidity. A less invasive alternative is percutaneous pulmonary valve implantation (PPVI). Though studies have previously reported the safety and efficacy of the early generation transcatheter heart valves (THVs), data on more recent devices are severely lacking. METHODS AND RESULTS: We performed a multinational, multicentre, retrospective, observational registry analysis of patients who underwent PPVI using the Edwards SAPIEN XT THV...

Incidence and severity of both deep vein thrombosis and chronic venous insufficiency are increased with age. Today, however, the significance of these diseases in the elderly patient population are still poorly comprehended. Although most patients have a history of previous treatment, chronic venous insufficiency is usually encountered in the advanced clinical stage. As a result, there is an increase in mobility restrictions, the need for assistance in daily activities and the risk of falls in elderly patients...

Cardiovascular complications are included among the systemic effects of tyrosine kinase inhibitor (TKI)-based therapeutic strategies. To test the hypothesis that inhibition of Kit tyrosine kinase that promotes cardiac progenitor cell (CPC) survival and function may be one of the triggering mechanisms of imatinib mesylate (IM)-related cardiovascular effects, the anatomical, structural and ultrastructural changes in the heart of IM-treated rats were evaluated. Cardiac anatomy in IM-exposed rats showed a dose-dependent, restrictive type of remodeling and depressed hemodynamic performance in the absence of remarkable myocardial fibrosis...

Novel low-energy defibrillation therapies are thought to be driven by virtual-electrodes (VEs), due to the interaction of applied monophasic electric shocks with fine-scale anatomical structures within the heart. Significant inter-species differences in the cardiac (micro)-anatomy exist, however, particularly with respect to the degree of endocardial trabeculations, which may underlie important differences in response to low-energy defibrillation protocols. Understanding the interaction of monophasic electric fields with the specific human micro-anatomy is therefore imperative in facilitating the translation and optimisation of these promising experimental therapies to the clinic...

Structural heart disease is a rapidly evolving field, and approaches to procedural training are not standardized. We describe a novel modular approach to procedural training that considers each procedure as a series of building blocks that may be taught and assessed separately. Ten key structural heart disease building blocks can be identified, which, when combined with the cognitive skills of structural intervention and device-specific training, allow appropriate planning and implementation of structural procedures...

Tricuspid regurgitation (TR) is a very frequent manifestation of valvular heart disease. It may be due to the primary involvement of the valve or secondary to pulmonary hypertension or to the left-sided heart valve disease (most commonly rheumatic and involving the mitral valve). The pathophysiology of secondary TR is complex and is intrinsically connected to the anatomy and function of the right ventricle. A systematic multimodality approach to diagnosis and assessment (based not only on the severity of the TR but also on the assessment of annular size, RV function and degree of pulmonary hypertension) is, therefore, essential...

The advent of more advanced 3D image processing, reconstruction, and a variety of three-dimensional (3D) printing technologies using different materials has made rapid and fairly affordable anatomically accurate models much more achievable. These models show great promise in facilitating procedural and surgical planning for complex congenital and structural heart disease. Refinements in 3D printing technology lend itself to advanced applications in the fields of bio-printing, hemodynamic modeling, and implantable devices...

BACKGROUND: Aortic coarctation (AC) is most commonly identified in pediatric patients; however, adults can present with late sequelae of untreated coarctation or complications of prior open repair. To date, there are limited data about the role of thoracic endovascular aortic repair (TEVAR) in this group of patients. The purpose of this analysis was to describe our experience with management of adult coarctation patients using TEVAR. METHODS: All TEVAR patients treated for primary coarctation or late sequelae of previous open repair (eg, pseudoaneurysm, recurrent coarctation or anastomotic stenosis related to index open coarctation repair) were reviewed...

The success and continued rapid clinical integration of transcatheter valve technologies relies on imaging modalities to guide safe and effective device deployment. In particular, cardiac imaging, using both echocardiography and CT, is an integral resource for the multidisciplinary team. These modalities can provide valuable insight for the proceduralist at each stage of transcatheter-based valve insertion, as they can be used reliably to define the anatomy of interest and its relationship to surrounding structures, determine accurate device sizing, assess patients for valve-in-valve procedures, and screen for adverse features or procedural contraindications...

PURPOSE: Suprasternal transcatheter aortic valve replacement offers patients, with unsuitable femoral artery anatomy, an alternative to transapical, direct aortic, and subclavian approaches. DESCRIPTION: The Transit System (Aegis Surgical, Galway, Ireland) enables transcatheter aortic valve replacement directly into the ascending aorta or innominate artery through a small, suprasternal incision. The valve introducer sheath is inserted through a standard pursestring suture, which facilitates secure arterial closure...

We present the case of a female adult with complex cyanotic congenital heart disease who had long-standing thoracic aortic obstruction due to scarring from earlier surgical procedures. She was symptomatic but felt to be too high risk for surgical intervention. With careful planning, she was able to undergo successful stenting of her aorta with subsequent clinical improvement. This case highlights some of the complexities of caring for adults with congenital heart disease and the importance of a thorough understanding of their anatomy and physiology and prior interventions before undertaking interventions...

AIM: This proof of principle study aims to show the direct relationship between cardiac anatomy and the mean cardiac activation path as captured by the 12 lead ECG derived mean temporal-spatial isochrones (mean TSI) path. METHODS: To obtain the mean TSI signal a vector cardiographic (VCG) signal is constructed from the 12 lead ECG. The construction of the VCG signal uses a model of the heart and torso with patient specific electrode extracted from a 3D photo. The propagation of the activation through the heart is captured by estimating the mean of a cardiac activation isochrone using this VCG signal...

Cardiac computed tomography angiography (CCTA) is a noninvasive imaging technique that has been rapidly adopted into clinical practice. Over the past decade, technological advances have improved CCTA accuracy, and there is an increasing amount of data supporting its prognostic value in the assessment of coronary artery disease. Recently, "appropriate use criteria" has been used as a tool to minimize inappropriate testing and reduce patient exposure to unnecessary risk and inconclusive studies. This review will summarize the appropriate uses of CCTA in patients before and after cardiac surgery...
