Preclinical Serial Assessment of Virtual Physiology After Implantation of a Novel Endoluminal Resorbable Fibrillated Scaffold

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The resorbable fibrillated scaffold (RFS) is a novel electrospun, polylactide‐based endoluminal scaffold developed for peripheral arterial applications. Its porous microfibre architecture is intended to support host cell infiltration and vascular restoration.

Percutaneous Transaxillary Access for Large‐Bore Cardiovascular Interventions: Evidence, Technique, and Complication Management

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Percutaneous transaxillary access is an established alternative to transfemoral large‐bore arterial access for transcatheter structural heart interventions and mechanical circulatory support (MCS). Although useful for overcoming hostile iliofemoral anatomy and providing prolonged support and patient mobilization in case of MCS, the axillary ...

Comparison of Immediate Versus Staged Complete Revascularization in Patients With Index PCI Coronary Complications: A Study on Clinical Outcomes and Predictors of Complications

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background In patients with acute coronary syndrome (ACS) and multivessel disease (MVD), complete revascularization (CR) improves clinical outcomes compared with culprit‐only percutaneous coronary intervention (PCI). However, the optimal timing of CR, immediate (ICR) versus staged (SCR), remains debated.

VERMONT μQFR: Diagnostic Accuracy of Murray Law‐Based 2D‐μQFR Compared to 3D‐μQFR and vFFR

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Murray law‐based quantitative flow ratio (μQFR) is an angiography‐derived physiological index that utilizes a single angiographic projection with artificial intelligence‐guided vessel segmentation. Aims To evaluate the diagnostic accuracy and time efficacy of 2D‐μQFR against wire‐based fractional flow reserve (FFR ≤ 0.80), compare ...

Evaluation of Treatment Response of Calcified Nodules and Nodular Calcified Lesions Using Mean Density on Coronary Computed Tomography Angiography

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Calcified nodules (CN) and nodular calcifications (NC) present significant challenges during percutaneous coronary intervention (PCI) because of their protruding morphology and high rigidity, which often result in inadequate stent expansion and suboptimal procedural outcomes.

Four simultaneous anterior cerebral artery aneurysms (three initially unsuspected) with surgical treatment

Radiology Case Reports, 2019
Distal anterior cerebral artery aneurysms are rare, comprising approximately 6% of all intracranial aneurysms. These aneurysms tend to be smaller in size, broad-based, associated with additional aneurysms and at arterial branching sites, which can make ...
