Clinical and Physiological Predictors of Acetylcholine‐Induced Coronary Spasm in ANOCA/INOCA Patients: A Retrospective Cohort Study

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background A substantial proportion of patients with angina and/or ischemia are found to have non‐obstructive coronary arteries (ANOCA/INOCA). Their symptoms can sometimes be explained by coronary microvascular dysfunction and/or vasospasm. Selecting patients for acetylcholine testing remains challenging, and the procedure is not trivial in ...

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.

Influence of the Residual Gensini Score on Prognosis of Patients With ST‐Elevation Myocardial Infarction

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The residual Gensini score (rGS) was developed to quantify the severity of coronary atheroma burden after coronary revascularisation. The predictive value of the rGS for clinical outcomes in patients with ST‐segment elevation myocardial infarction (STEMI) remains unexplored.

Feasibility and Safety of Distal Transradial Access in Patients With Out‐of‐Hospital Cardiac Arrest Undergoing Emergency PCI: A Single‐Center Retrospective Study

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Distal transradial access (dTRA) has gained attention for its lower risk of vascular complications compared to conventional transradial access (TRA). However, its feasibility and safety in patients with out‐of‐hospital cardiac arrest (OHCA) undergoing emergency percutaneous coronary intervention (PCI) remain uncertain.

Cerebrovascular Events in Aortic Stenosis: From Native Valve Disease to TAVR‐Specific Risk and Prevention

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Aortic stenosis (AS) is associated with a heightened burden of cardiovascular comorbidities, atrial fibrillation (AF), and progressive valvular calcification, all of which may contribute to cerebrovascular events across the disease continuum.

Role of Neuroimaging Before Coronary Angiography in Patients With Out‐of‐Hospital Cardiac Arrest

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Patients presenting following out‐of‐hospital cardiac arrest (OOHCA) often require emergency coronary angiography. Presentations can be associated with syncope or head‐trauma. Aims We investigated the impact and utility of pre‐coronary angiography CT‐Brain (CT‐B) in patients following OOHCA on clinical outcomes.
