Side Cell Dilation of Jailed Pulmonary Veins After Stenting Improves Vessel Preservation in Pediatric Pulmonary Vein Stenosis.

Introduction: Endovascular stent placement for pulmonary vein stenosis (PVS) provides effective obstruction relief. Due to small patient size and limited length options of available stents, pulmonary vein branches can be covered ("jailed") during stenting. The natural history of jailed veins, and whether side cell dilation (SCD) modifies this natural history, is unknown.

An Initial Experience in the Use of 3D ICE for the Periprocedural Guidance of Percutaneous ASD Closure at a Tertiary Pediatric Center.

The dynamic, multiplanar nature of the atrial septum can make ASDs challenging to characterize with 2D imaging. 3D imaging instantly profiles defect(s) in a single, en face view. 2D ICE-guided ASD device closure in the pediatric population has been reported, but 3D ICE-guided closure has not, and the correlation of 3D ICE measurements with fluoroscopic balloon-sizing diameter (BSD) remains unstudied.

Comparative Performance of Ante-Mortem Diagnostic Assays for the Identification of -Infected Domestic Dogs ().

The domestic dog () is a competent host for () infection but no ante mortem diagnostic tests have been fully validated for this species. The aim of this study was to compare the performance of ante mortem diagnostic tests across samples collected from dogs considered to be at a high or low risk of sub-clinical infection. We previously tested a total of 164 dogs at a high risk of infection and here test 42 dogs at a low risk of infection and 77 presumed uninfected dogs with a combination of cell-based and/or serological diagnostic assays previously described for use in non-canid species.

Cytokine and Chemokine Responses of Peripheral Blood Mononuclear Cells from Dogs Infected with .

Mycobacterial infections are an important emerging zoonosis in companion animals for which diagnostic options remain imperfect, and the canine immunological response to these infections has been poorly investigated. We sought to further define the cellular response of peripheral blood mononuclear cells (PBMCs) from dogs infected with , as determined using a commercial interferon-gamma response assay (IGRA). To this end, PBMCs from healthy or infected dogs were collected.

Pre-Catheterization Computed Tomography Angiography Aids in the Selection of Ductus Arteriosus Stent Length for Ductal-Dependent Pulmonary Blood Flow.

PDA stenting is increasingly utilized for patients with ductal-dependent pulmonary blood flow. Predicting optimal stent length prior to and during the intervention remains a challenge. The utility of pre-catheterization computed tomography angiography (CTA) to predict stent length was evaluated.

Differences in outcomes between surgical pericardial window and pericardiocentesis in children with postpericardiotomy syndrome.

Children with postpericardiotomy syndrome may develop hemodynamically significant pericardial effusions warranting drainage by surgical pericardial window or pericardiocentesis. The optimal approach is unknown. We performed a retrospective observational study at two pediatric cardiac centers.

Review canine tuberculosis - An emerging concern.

Canine mycobacterial disease was first recognised over 100 years ago but is now an emerging concern. All reported cases of tuberculous disease in dogs have been caused by infection with one of three Mycobacterium tuberculosis-complex (MTBC) organisms (M. tuberculosis, Mycobacterium bovis, and Mycobacterium microti).

Interventions on residual lesions in patients with heterotaxy syndrome following orthotropic heart transplantation: A single-center experience.

Background: Heterotaxy syndrome (HS) is a defect in lateralization which often results in complex intra and extracardiac abnormalities. Orthotropic heart transplantation (OHT) in HS involves intricate and individualized modifications to surgical technique. Post-OHT outcomes are worse in patients with HS, however, the impact of post-OHT residual lesions has not yet been characterized.

Histopathology, mRNA expression profile, and donor-derived cell-free DNA for assessment of rejection in pediatric heart transplantation.

Background: The relationship between histopathologic and molecular ("MMDx"®) assessments of endomyocardial biopsy (EMB) and serum donor-derived cell-free DNA (ddcfDNA) in acute rejection (AR) assessment following pediatric heart transplantation (HT) is unknown.

Methods: EMB sent for MMDx and histopathology from November 2021 to September 2022 were reviewed. MMDx and histopathology results were compared.

Late Diagnosis of Residual Major Aortopulmonary Collateral in a Patient with Tetralogy of Fallot.

• Residual MAPCAs result in post-tricuspid shunt and PH. • Distinction between PH and conduit stenosis requires attention to TTE findings. • Management of complex adult CHD should be reserved for centers with expertise.

Canine tuberculosis: A review of 18 new and 565 previously reported confirmed cases.

Cases of canine tuberculosis, a zoonotic infection of significant public health significance, are typically only sporadically reported in the literature. For this observational study, case details were collated both retrospectively and prospectively for dogs infected with Mycobacterium tuberculosis-complex (MTBC) organisms. A total of 18 previously unreported cases as well as 565 historically reported confirmed cases were reviewed.

How and why pet cats are fed the way they are: a self-reported owner survey.

Objectives: This study used an owner-directed online questionnaire to collect data regarding their food and water provision for their pet cats. The survey was conducted in 2019.

Methods: The anonymous online 30-question survey was available via vetprofessionals.

Left Atrial Hypertension and Respiratory Failure Requiring Venoarterial ECMO After Transcatheter Pulmonary Valve Replacement.

A 33-year-old woman with aortic valve stenosis status-post Ross at age 6 years developed symptomatic right heart failure from right ventricle to pulmonary artery conduit stenosis. Conduit rehabilitation and transcatheter pulmonary valve replacement resulted in acute left atrial hypertension and respiratory failure requiring venoarterial extracorporeal membrane oxygenation and atrial septal defect creation as a bridge to recovery.

Equine conjunctival haemangiosarcoma: Clinical presentation, management, and outcome of seven cases in the United Kingdom.

Background: Only 27 cases of equine conjunctival haemangiosarcoma have been reported in the literature over the past 37 years. Out of these, 22% of cases were lost to follow-up, 52% were euthanized, and 26% survived. A scarcity of cases and information is available for this rarely seen conjunctival tumour.

Echocardiogram-Guided Balloon Valvuloplasty of the Aortic Valve in Neonates and Infants Reduces Contrast Exposure with Maintained Efficacy and Less Aortic Regurgitation.

Balloon aortic valvuloplasty (BAV) is performed in children with significant aortic stenosis (AS). Traditionally, contrast angiography measures the annulus and assesses aortic regurgitation (AR) after each dilation. Echocardiographic guidance is hypothesized to reduce contrast and radiation exposure, without compromising efficacy or safety.

A Volume Challenge Reveals the Diagnosis of Pediatric Restrictive Cardiomyopathy.

A healthy 11-year-old girl presented with exercise intolerance of unclear etiology, and her physical exam was notable for a 3/6 systolic ejection murmur at the left upper sternal border with radiation to the back. Extensive noninvasive workup consisted of ECG, transthoracic echocardiogram, and cardiac MRI/MRA, which were all nondiagnostic. She was ultimately referred for cardiac catheterization.

Magnetic Resonance Imaging in Pediatric Myocarditis: Trends and Associations With Cost and Outcome.

Background: Cardiac magnetic resonance (CMR) provides tissue characterization and structural and functional data. CMR has high sensitivity and specificity for myocarditis in adults and children. The relationship between pediatric CMR use, cost, and clinical outcome has not been studied.

Experimental Infection of Captive Red Foxes () with .

In Europe, animal tuberculosis (TB) due to involves multi-host communities that include cattle and wildlife species, such as wild boar (), badgers () and red deer (). Red fox () infections have also been recently reported in some TB endemic regions in the Iberian Peninsula and France, with some of the infected animals shedding in urine and feces. In order to understand the pathogenesis of infection in foxes and the associated risk of transmission, 12 captive foxes (6 females and 6 males) were inoculated orally with 2 × 10 colony-forming units of a French field isolate of .

Perspective on Cerebral Autoregulation Monitoring in Neonatal Cardiac Surgery Requiring Cardiopulmonary Bypass.

The autoregulation of cerebral blood flow protects against brain injury from transient fluctuations in arterial blood pressure. Impaired autoregulation may contribute to hypoperfusion injury in neonates and infants. Monitoring cerebral autoregulation in neonatal cardiac surgery as a guide for arterial blood pressure management may reduce neurodevelopmental morbidity.
