C-Arm Cone Beam CT-Guided Preoperative Microcoil Pulmonary Ground Glass Nodule Localization: Diagnostic and Surgical Advantage.

Objective: This study evaluates the effectiveness and safety of C-arm cone beam CT (CBCT)-guided microcoil localization combined with uniportal video-assisted thoracoscopic surgery (VATS) for the management of small, difficult-to-localize ground-glass opacities (GGOs) and sub-solid nodules in the lungs.

Methods: We retrospectively analyzed data from 13 patients with single, small, peripheral, non-subpleural GGOs or SSN. All patients underwent successful microcoil localization using CB-CT guidance followed by uniportal VATS resection.

Mid-Term Recovery of Right Ventricular Function and Improvement of Left Ventricular Function After Da Silva Cone Procedure for Ebstein Anomaly.

Background: The Da Silva Cone procedure for Ebstein anomaly has dramatically improved tricuspid valve competence and clinical outcomes. However, preoperative left ventricular (LV) dysfunction and immediate postoperative right ventricular (RV) systolic dysfunction are frequently observed. While excellent valve outcomes are well established, recovery of biventricular function following the Cone remains less defined.

Defining diastolic dysfunction post-Fontan: Threshold, risk factors, and associations with outcomes.

Background: Following the Fontan procedure, patients with single ventricle physiology are at high risk of diastolic dysfunction (DD) and elevated end-diastolic pressure (EDP).

Objective: This study aims to determine (1) the optimal EDP threshold correlated with adverse outcomes post-Fontan and (2) the clinical and imaging predictors of DD.

Methods: The study included patients from the Fontan Outcome Registry using CMR Examinations (FORCE) who underwent cardiac catheterization and cardiac magnetic resonance (CMR) within a 2-year window.

Differences in Exercise Performance in Fontan Patients with Extracardiac Conduit and Lateral Tunnel: A FORCE Fontan Registry Study.

To explore the differences in exercise capacity between the extracardiac conduit (ECC) and lateral tunnel (LT) Fontan. 2169 patients (36% LT ( = 774); 64% ECC ( = 1395)) underwent a Fontan operation between 2000 to 2023 in a multi-institutional Fontan registry. LT patients were age-matched to ECC patients, and cardiopulmonary exercise test (CPET) results were compared.

The long-term effect of the Fontan fenestration on clinical outcomes: A FORCE registry study.

Background: The long-term effect of open fenestration in Fontan patients is unclear, leading to wide practice variation of fenestration creation and closure. We evaluated the long-term outcomes of the fenestration using data from the Fontan Outcome Registry using Cardiac Magnetic Resonance Examinations (FORCE) Study.

Methods: Patients were categorized by fenestration status determined by post-Fontan cardiac magnetic resonance imaging (CMR) as open fenestration, nonfenestrated Fontan, spontaneous closure, and device closure.

Toward "S"-Shaped 3D-Printed Soft Robotic Guidewires for Pediatric Patent Ductus Arteriosus Endovascular Interventions.

Patent Ductus Arteriosus (PDA) is a heart condition in which the ductus arteriosus-a blood vessel connecting the pulmonary artery to the aorta in a fetus-fails to undergo closure after birth. A PDA can be an important factor in neonates born with severe congenital heart disease (CHD) or born prematurely. With the advent of new intravascular stent technologies, treatments based on ductus arteriosus stenting can now be completed in many cases; however, difficulties remain in accessing the ductus arteriosus in small babies successfully using current guidewire-catheter systems.

Free-breathing multi-parametric SASHA (mSASHA) mapping provides reliable non-contrast myocardial characterization in a pediatric and adult congenital population.

Parametric mapping has become a standard of care technique for the non-invasive assessment of myocardial edema and fibrosis. Conventional MOLLI-based T1 mapping is susceptible to many confounding effects particularly in the pediatric population. The requirement for compliant breath holds is a major limitation for younger or more ill patients.

National Multicenter Study on the Prevalence of Carbapenemase-Producing Enterobacteriaceae in the Post-COVID-19 Era in Argentina: The RECAPT-AR Study.

Unlabelled: The COVID-19 pandemic has exacerbated the global antimicrobial resistance (AMR) crisis. Consequently, it is more urgent than ever to prioritize AMR containment and support countries in improving the detection, characterization, and rapid response to emerging AMR threats. We conducted a prospective, multicenter study to assess the prevalence of carbapenemase-producing Enterobacterales in infectious processes in Argentina during the post-COVID-19 pandemic period and explore therapeutic alternatives for their treatment (RECAPT-AR study).

Longitudinal Assessment of T1 Mapping Trends Disease in Pediatric Patients With Heart Transplant.

Background: Surveillance for heart transplant rejection by endomyocardial biopsy is invasive and may yield false negatives. T1 and T2 mapping from cardiac magnetic resonance can demonstrate elevations with rejection. We sought to evaluate longitudinal changes in T1 and T2 mapping in pediatric patients with heart transplant.

Impact of guideline directed medical therapy on myocardial function in adults with congenital heart disease.

Background: Guideline-directed heart failure therapy with angiotensin receptor blocker/neprilysin inhibitor (ARNi) and sodium-glucose transporter inhibitors (SGLT2i) has been incrementally beneficial in improving outcomes in heart failure patients.

Objective: Evaluate the feasibility and efficacy of guideline-directed medical therapy (GDMT) in adults congenital heart disease (ACHD) patients.

Methods: In a retrospective cohort study, ACHD patients with either New York Heart Association (NYHA) Class II symptoms or systemic ejection fraction (EF) <45%, optimized on a combination of beta-blocker (BB), ARNi, mineralocorticoid receptor antagonist (MRA) and SGLT2i were evaluated.

Large Right Atrial Size on Cardiac MRI is Associated with Post-operative Right Ventricular Dysfunction After the Cone Operation for Ebstein Anomaly.

The cone operation has revolutionized care for patients with Ebstein anomaly; however, acute post-operative right ventricular dysfunction (RVD) is common in this patient population. A single-center, retrospective review of 28 patients with Ebstein anomaly who underwent cardiac MRI (CMR) prior to cone reconstruction of the tricuspid valve was conducted. Measurements of atrial and ventricular size/function were assessed.

Assessing Left Ventricular Pathology in Patients with Ebstein Anomaly Using Cardiovascular Magnetic Resonance: Looking Past the Right Heart.

Ebstein Anomaly (EA) is a malformation of the right heart, but there is data to suggest that the left ventricle (LV) can suffer from intrinsic structural and functional abnormalities which affect surgical outcomes. The LV in patients with EA is hypertrabeculated with abnormalities in LV function and strain. In this retrospective single-center study, patients with EA who underwent pre-operative cardiac MRI (CMR) between the periods of 2014-2024 were included along with a group of healthy-age-matched controls.

Augmented Biphasic Breathing Using Sniff and an Oral Positive Expiratory Pressure Device (Sniff-PEP) in Fontan Patients.

The use of an oral positive expiratory pressure device (oPEP) with sniff breathing (Sniff-PEP) mimics biphasic ventilation. Biphasic ventilation increases pulmonary blood flow and cardiac output in Fontan patients. The aim of this study was to assess the effect of Sniff-PEP on Fontan flow velocities.

T1 mapping: a non-invasive tool to assess the systemic right ventricle.

Ventricular remodeling leads to fibrotic changes in systemic right ventricles (RV). Native T1 mapping provides a quantitative measure in myocardial tissue characterization. The aim of our study was to correlate native T1 values of the systemic RV to function and volumetric data.

Patient-specific tissue engineered vascular graft for aortic arch reconstruction.

Objectives: The complexity of aortic arch reconstruction due to diverse 3-dimensional geometrical abnormalities is a major challenge. This study introduces 3-dimensional printed tissue-engineered vascular grafts, which can fit patient-specific dimensions, optimize hemodynamics, exhibit antithrombotic and anti-infective properties, and accommodate growth.

Methods: We procured cardiac magnetic resonance imaging with 4-dimensional flow for native porcine anatomy (n = 10), from which we designed tissue-engineered vascular grafts for the distal aortic arch, 4 weeks before surgery.

Tetralogy of Fallot regurgitation energetics and kinetics: an intracardiac flow analysis of the right ventricle using computational fluid dynamics.

Repaired Tetralogy of Fallot (rTOF) patients suffer from pulmonary regurgitation and may require pulmonary valve replacement (PVR). Cardiac magnetic resonance imaging (cMRI) guides therapy, but conventional measurements do not quantify the intracardiac flow effects from pulmonary regurgitation or PVR. This study investigates intracardiac flow parameters of the right ventricle (RV) of rTOF by computational fluid dynamics (CFD).
