Congenital complete absence of the pericardium is a rare condition, often difficult to diagnose due to its incidental discovery or nonspecific clinical manifestations. Instrumental investigations commonly used as initial approaches, such as chest radiography and electrocardiogram, are often insufficient. Echocardiography is an imaging technique that is used for the initial evaluation of pericardial diseases. However, echocardiography does not offer a physiological anatomical delineation of the pericardium and can be affected by operator dependency, acoustic and nontraditional imaging windows...

BACKGROUND: The role of the number of involved structures (NIS) in thymic epithelial tumors (TETs) has been investigated for inclusion in future staging systems, but large cohort results still are missing. This study aimed to analyze the prognostic role of NIS for patients included in the European Society of Thoracic Surgeons (ESTS) thymic database who underwent surgical resection. METHODS: Clinical and pathologic data of patients from the ESTS thymic database who underwent surgery for TET from January 2000 to July 2019 with infiltration of surrounding structures were reviewed and analyzed...

We report the case of a 9-year-old male with severe congenital pulmonary valve stenosis referred to our centre for percutaneous valvotomy. On admission, trans-thoracic echocardiogram confirmed a unicuspid pulmonary valve with a peak/mean pulmonary valve gradient of 91/53 mmHg and a pulmonary annulus of 13.8 mm (-0.8 Z Score). It also showed an enlarged RV (RV/LV ratio 0,9). During cardiac catheterisation, an additional atrial septal defect (secundum) with significant left to right shunt (Qp/Qs > 2) was diagnosed, which was not amenable to percutaneous closure...

About 280 000 heart valve replacements are performed worldwide every year. Since the first prosthetic valve implantation in 1952 there have been notable developments. There are a lot of types of prosthetic valves that can be summarized into two categories: biological prosthetic valves or mechanical prosthetic valves. Biological prostheses, made of bovine or porcine pericardium, homografts, or autografts, degenerate over time becoming dysfunctional. Mechanical prostheses have a potentially unlimited lifespan but require oral anticoagulation which can affect patients' quality of life...

Due to the increasing aging population and the advancements in transcatheter aortic valve replacement (TAVR), the use of bioprosthetic heart valves (BHVs) in patients diagnosed with valvular disease has increased substantially. Commercially available glutaraldehyde (GA) cross-linked biological valves suffer from reduced durability due to a combination of factors, including the high cell toxicity of GA, subacute thrombus, inflammation and calcification. In this study, oxidized chondroitin sulfate (OCS), a natural polysaccharide derivative, was used to replace GA to cross-link decellularized bovine pericardium (DBP), carrying out the first crosslinking of DBP to obtain OCS-BP...

The so-called Commando procedure, initially described by David and colleagues, consists in the reconstruction of the mitro-aortic fibrous lamina by a patch that enlarges both annuli. Its use has been described to upsize the aortic and mitral annulus for double valve replacement in adolescents. We describe a modified technique of this reconstruction of the fibrous skeleton of the heart, combined with Konno procedure to further enlarge the aortic annulus. In modified Commando procedure, following the reconstruction of aortomitral continuity with a bovine pericardium CardioCel patch (Admedus Regen Pty Ltd, Perth, WA, Australia), an aortic valved conduit that was made on the bench in order to have bottom skirt that enabled the suturing of the composite conduit far inside the left ventricle outflow tract...

A primary epithelioid angiosarcoma of the pericardium is a rare soft tissue malignancy. This report describes a young adult woman who presented with progressive dyspnea and pericardial effusion. She was found to have pericardial mass on imaging along with extensive myocardial infiltration. The biopsy of the mass revealed epithelioid angiosarcoma, which was CD34 and CD31-immuno-positive. Due to unresectable disease, she was given a trial of immunotherapy followed by conventional chemotherapy. She showed partial response on interim assessment, but progressed soon after the completion of six cycles and succumbed to her rapidly progressive illness within nine months of diagnosis...

Valvular structural deterioration is of particular concern for transcatheter aortic valve replacements due to their suspected shorter longevity and increasing use in younger patient populations. In this work we investigated the mechanical and microstructural changes in commercial TAVR valves composed of both glutaraldehyde fixed bovine and porcine pericardium (GLBP and GLPP) following accelerated wear testing (AWT) as outlined in ISO 5840 standards. This provided greater physiological relevance to the loading compared to previous studies and by utilizing digital image correlation we were able to obtain strain contours for each leaflet pre and post fatigue and identify sites of fatigue damage...

Various complications can occur during robot-assisted thoracic surgery for mediastinal tumors owing to carbon dioxide (CO2) insufflation. This study reports the case of a 43-year-old woman who underwent robot-assisted surgery for an anterior mediastinal tumor with the subxiphoid approach. Shortly after starting CO2 insufflation, the blood pressure decreased significantly. Subsequent examination of the mediastinum revealed a left-sided pericardial injury. Cardiac tamponade due to entry of CO2 gas into the pericardial cavity was suspected...

Since the introduction of transcatheter aortic valve (AV) implantation as a viable option, surgical bioprosthetic AVs have recently started incorporating shorter struts considering future valve-in-valve procedures. However, the effect of leaflet coaptation geometry on the longevity of these valves remains unexplored. To address this gap, we performed a finite element analysis on bioprosthetic AVs with varying strut heights using a two-way fluid-structure interaction method. To establish a baseline, we used a standard height based on a rendered platform image of the CE PERIMOUNT Magna Ease valve from Edward Lifesciences in Irvine, CA...

BACKGROUND: The fascial anatomy of the anterior mediastinum has not been thoroughly investigated. Only the sternopericardial ligament (SPL) has been defined and is often described as two independent tendons. However, these descriptions differ from our observations of thoracic surgery. Here, we aimed to precisely investigate the fascial anatomy, particularly the SPL, of the anterior mediastinum. METHODS: We surgically and radiologically observed and analyzed the fascial anatomy of the anterior mediastinum in patients who underwent surgery for anterior mediastinal disease at our institution between July 2009 and August 2018...

In the human cardiovascular system (CVS), the interaction between the left and right ventricles of the heart is influenced by the septum and the pericardium. Computational models of the CVS can capture this interaction, but this often involves approximating solutions to complex nonlinear equations numerically. As a result, numerous models have been proposed, where these nonlinear equations are either simplified, or ventricular interaction is ignored. In this work, we propose an alternative approach to modelling ventricular interaction, using a hybrid neural ordinary differential equation (ODE) structure...

Acute pericarditis is an inflammatory condition involving the pericardium, the double-layered sac that surrounds the heart. It is characterized by chest pain, typically pleuritic and sharp, along with other clinical and laboratory findings indicative of pericardial inflammation. While acute pericarditis following influenza vaccination is rare, it has been reported in medical literature. The relationship between vaccinations, including the influenza vaccine, and pericarditis is particularly interesting, as it has implications for public health and vaccination programs...

Solitary fibrous tumors (SFTs) are rare mesenchymal neoplasms constituting less than 2% of all soft tissue tumors. They typically originate in the thoracic cavity, mainly in the pleura, but can also occur in other various sites such as lung parenchyma, pericardium, and bronchus. In this study, a 49-year-old non-smoking female with a history of allergies presented to our pulmonary clinic with a chronic cough. An explorative bronchoscopy revealed an intrabronchial mass in the left superior bronchi, and a 68 Ga-DOTATOC positron emission computed tomography suggested a carcinoid tumor...
