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.
