Transcatheter Repair of Sinus Venosus Defect Using a 12‐zig Covered Cheatham‐Platinum Stent in Large Superior Vena Cava—Right Atrium Junctions: Early Multicenter Experience

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Sinus venosus defect (SVD) is a rare congenital heart anomaly characterised by an abnormal communication between the atria, often associated with partial anomalous pulmonary venous connection (PAPVC). Traditional surgical repair carries significant risks, prompting exploration into less invasive transcatheter approaches.

Unveiling the Microvasculature: The Index of Microcirculatory Resistance and Its Expanding Role in Cardiovascular Care

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Index of microcirculatory resistance (IMR) is a cutting‐edge, wire‐based tool that advances the capability assessment of coronary microvascular function. By utilizing distal coronary pressure and mean transit time under maximal hyperemia, IMR delivers consistent, reproducible insights into the microvasculature's dynamic health.

Echocardiography‐Assisted Stenting of the Ductus Venosus in Infracardiac TAPVC: Report of a New Technique and Review of the Literature

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Neonates with infracardiac total anomalous pulmonary venous connection (TAPVC) frequently require urgent treatment. If surgical repair is contraindicated due to extreme prematurity, interventional stenting of the ductus venosus (DV) has been introduced successfully to postpone surgery.

Clinical and Echocardiographic Outcomes After Implantation of the ALLEGRA Transcatheter Valve Using the Fully Repositionable IMPERIA Delivery System: One‐Year Results of the EMPIRE I Study

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The EMPIRE I study assessed the early (30 days) safety and efficacy of a new fully repositionable delivery system (IMPERIA) for the commercially available ALLEGRA transcatheter aortic valve in patients with either severe native aortic stenosis or a degenerated surgical bioprosthesis.

Numerical investigation on the influence of mesoscopic deformation on contact area and hydraulic aperture to fracture seepage

Deep Underground Science and Engineering, EarlyView.
Fluid flow through a single fracture is commonly described by the cubic law. However, deviations from this model are expected because natural fracture surfaces are rough and in contact with each other in discrete regions. In this study, the interactions between fracture closure, contact area, and hydraulic characterization of mesoscopic‐scale rough ...

Progression and prognostic significance of electrocardiographic findings in patients with cardiac amyloidosis

ESC Heart Failure, Volume 12, Issue 2, Page 809-818, April 2025.
Abstract Aims This study aimed to evaluate the change of the main electrocardiographic (ECG) characteristics and their prognostic role across the main subtypes of cardiac amyloidosis [light‐chain amyloidosis (AL) and hereditary (ATTRv) and wild‐type transthyretin amyloidosis (ATTRwt)].
