Pericardial diseases

Hydatidosis, a distinctive parasitic ailment, exhibits a broad range of imaging characteristics influenced by the growth stage, resultant complications, and tissue involvement. Its occurrence throughout the human anatomy underscores its ubiquitous propensity. Despite its relatively infrequent manifestation as diffuse hydatosis, the disease assumes particular significance in rural regions. Given its detrimental complications and resemblance to other cystic conditions, vigilance towards the potential presence of this ailment becomes imperative...

BACKGROUND: Partial anomalous pulmonary venous return (PAPVR) can be surgically corrected using a pericardial baffle. This baffle can become obstructed post-surgery, leading to pulmonary hypertension and right heart dysfunction if not detected and corrected. CASE SUMMARY: We describe three patients with occluded PAPVR baffles who underwent drug-coated balloon angioplasty and stenting of the obstructed baffle. In each case, baffle obstruction was detected post-operatively on surveillance cross-sectional imaging, and an invasively measured pulmonary capillary wedge-to-left atrium gradient was noted to be elevated...

BACKGROUND: A prenatal fetal mediastinal cyst is a benign disease. However, if a cyst enlargement grows, it may compress the adjacent organs and affect the fetal cardiopulmonary function. This study aimed to compare and analyze the prenatal ultrasound characteristics of different mediastinal cysts, and to evaluate the pregnancy outcome of the fetus and the factors affecting the prognostic of the fetus. To compare and analyze the prenatal ultrasound characteristics of different types of mediastinal cysts, and to evaluate the fetal pregnancy outcome and the influencing factors of fetal prognosis...

In a 39-year-old male with mitral valve endocarditis, after 6 weeks of intravenous antibiotics, echocardiography confirmed multiple vegetations on both leaflets, a flail posterior leaflet flail and contained perforation of the anterior leaflet in a windsock-like morphology. All vegetations, diseased and ruptured chords and the windsock-like contained rupture of the anterior leaflet were carefully resected via a right minithoracotomy and with femoral cannulation. Three repair techniques were blended to reconstruct the valve: (1) A large, infected portion of the prolapsing posterior leaflet was resected in a triangular fashion, and the edges were re-approximated using continuous 5-0 polypropylene sutures...

BACKGROUND: The microbiome likely plays a role in tuberculosis (TB) pathogenesis. We evaluated the site-of-disease microbiome and predicted metagenome in people with presumptive tuberculous pericarditis, a major cause of mortality, and explored for the first time, the interaction between its association with C-reactive protein (CRP), a potential diagnostic biomarker and the site-of-disease microbiome in extrapulmonary TB. METHODS: People with effusions requiring diagnostic pericardiocentesis (n=139) provided background sampling controls and pericardial fluid (PF) for 16S rRNA gene sequencing analysed using QIIME2 and PICRUSt2...

Pericardial mesothelioma (PM) is rare with only 200 cases recorded, and a post-mortem prevalence of <0.0022%. It is the third most common cardiac/pericardial tumour, behind angiosarcoma and rhabdomyosarcoma. PM incidence increases with age, typically incidentally diagnosed between 50 and 70 years, with a 3:1 male predominance. Occasional PM can cause chest pain, dyspnoea, cough and even dysphagia. PMs are often misdiagnosed with only 25% of cases being antemortem diagnoses. Unlike pleural mesothelioma, the link between asbestos exposure and malignancy is less convincing, with only 20% of cases having known exposure...

A 62-year-old woman who had undergone mitral valve replacement 24 years ago was admitted to the hospital with congestive heart failure. She needed heart transplantation for stage D heart failure. Preoperative cardiac computed tomographic scans showed a severely calcified left atrium and a large right atrium. Given that the left atrium's calcification was too severe to suture, the calcified left atrial wall was broadly resected, and the resected left atrial wall was reconstructed with a bovine pericardial patch for anastomosis with the donor's left atrial wall...

BACKGROUND: Metastatic germ cell tumors (GCTs) involving body cavity effusions and cerebrospinal fluid (CSF) are rare. Diagnosis is challenging because of limited morphological and clinicopathological information in the literature. METHODS: A database search of our institution from 1990 to 2024 identified 27 cases of metastatic GCTs, comprising five pediatric and 22 adolescent and adult patients, in serous cavities or the CSF, including peritoneal (15), pleural (nine), CSF (two), and pericardial (one) fluid...

Amyloidosis is a disease characterized by the deposition of protein fibrils. Cardiac involvement is a significant factor in determining prognosis. This study aimed to examine the clinical profile, outcomes, and long-term mortality rates in patients with transthyretin (ATTR) and amyloid light-chain (AL) amyloidosis. The retrospective cohort study included 94 patients with amyloidosis (69 with AL and 25 with ATTR amyloidosis) diagnosed between 2010 and 2022. The study involved multimodality imaging (ECG, echocardiography and cardiac magnetic resonance (CMR) data and survival analyses...

Cardiotoxicity in children is a potentially fatal complication after allogeneic hematopoietic stem cell transplantation (allo-HSCT); therefore, early identification of risk factors can improve patient prognosis. However, there are few data on the clinical characteristics of early-stage cardiotoxicity in children after allo-HSCT. We conducted a retrospective single-center study of pediatric patients who underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) between January 2016 and December 2022 at the Children's Hospital Affiliated with Chongqing Medical University to evaluate the clinical characteristics of early cardiac events (ECEs) after allo-HSCT and their impact on survival outcomes...

BACKGROUND: Leadless pacing has been established as an alternative approach to transvenous devices for selected patients. Often, leadless pacemaker (LP) implantation is a de novo procedure, but in an increasing number of patients, an LP is used after previous implantation of a conventional pacing system (CPS). METHODS: A retrospective analysis was conducted of the efficacy and safety of LP implantation in the context of a previously implanted CPS, from 2 large Swiss centres...

An 11-year-old female spayed German Wirehaired Pointer with a 1-week history of lethargy, hyporexia, diarrhea, and coughing presented with pericardial effusion causing cardiac tamponade. An echocardiogram revealed no structural cause for pericardial effusion. The pericardial effusion was an exudate with mixed macrophagic and neutrophilic inflammation. Morulae occasionally were found within neutrophils. The pericardial fluid and blood were qPCR and cPCR positive for Anaplasma phagocytophilum (NC State University, Vector-borne Disease Diagnostic Laboratory, Raleigh, NC)...

BACKGROUND: Multisystem inflammatory syndrome in children (MIS-C) shows a significant overlap of symptoms with other hyper-inflammatory diseases such as Kawasaki disease (KD), but the real difference of the two conditions is still matter of debate. Coronary artery lesions (CAL) are the most relevant complication in KD. Nonetheless, CAL, myocarditis, pericarditis, arrhythmia are the main cardiovascular complications in MIS-C. A close clinical assessment is mandatory, both at the diagnosis and during the follow-up, by ECG and echocardiography...

BACKGROUND: Although pneumonectomy has relatively high mortality and morbidity rates, it remains valid in the surgical treatment of lung cancer. This study aims to evaluate the prognostic significance of postoperative complications after pneumonectomy and demonstrate the risk factors related to early postoperative complications. METHODS: Patients who underwent pneumonectomy for non-small cell lung cancer between January 2008 and May 2021 were included in the study...

Inflammatory disease of the pericardium represents a relatively common presentation, especially among the young. For the most part, inflammatory pericardial disease can be expeditiously and effectively managed without significant sequelae. However, some individuals present with severe and recurrent illness, representing significant therapeutic challenges. During the past decade, there have been great strides made in developing an evidence-based approach to management of inflammatory pericardial disease, the result of which has been the development of (1) a systematic, protocoled approach to initial care; (2) targeted therapeutics; and (3) specialized, collaborative, and integrated care pathways...

INTRODUCTION: We undertook the first study from India to evaluate the long-term health effects of coronavirus disease 2019 (COVID-19). METHODS: The patients enrolled in our post-COVID-19 clinic were followed up for assessment at 1, 3, 6 and 12 months after recovery from acute disease prospectively. RESULTS: 200 patients with mean age of 50.72 years and 57.5% males were analysed. 42.5% had severe and 17% had moderate disease at the time of diagnosis...

Pericarditis is a well-known complication of hypothyroidism. Although pericarditis and pericardial effusions have been reported as rare complications of hyperthyroidism in adults, they are rarely reported in the pediatric population. In this case report, we describe a 12-year-old, previously healthy girl with nighttime chest pain, dyspnea, tachycardia, and abnormal thyroid function studies consistent with hyperthyroidism who was found to have pericarditis and pericardial effusion requiring pericardiocentesis...

BACKGROUND: Pericardial agenesis is a rare congenital heart disease characterized by a variable clinical presentation. CASE SUMMARY: A 32-year-old man was sent by an occupational health physician to our health care centre because of pathological electrocardiogram (ECG). On transthoracic echocardiogram, we had some difficulty to obtain a good quality of four-chamber apical view that was shifted upper and laterally towards the left anterior axillary line. Nonetheless, an abnormal diastolic expansion of the apex of the left ventricle (LV) that had an otherwise normal systolic function was detected...

BACKGROUND: Pericardial effusion requiring percutaneous or surgical-based intervention remains an important complication of a leadless pacemaker implantation. OBJECTIVE: The study sought to determine real-world prevalence, risk factors, and associated outcomes of pericardial effusion requiring intervention in leadless pacemaker implantations. METHODS: The National Inpatient Sample and International Classification of Diseases-Tenth Revision codes were used to identify patients who underwent leadless pacemaker implantations during the years 2016 to 2020...
