Can Ultrasound‐Guided in‐Plane Puncture Technique Enhance the Precision of Femoral Artery Access? The Randomized PARFEM Trial

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Ultrasound‐guided puncture of the common femoral artery (CFA) is assumed to be more precise than conventional techniques without ultrasound. However, previous comparative studies have shown partly contradictory results with regard to success of ultrasound‐guided puncture so that this method is not yet standard in transfemoral ...

Minimum Lumen Area Indexed to Left Ventricular Mass to Identify Functionally Significant Left Main Coronary Stenoses

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background and Aim Diagnosing significant left main coronary artery (LMCA) stenoses based on anatomical criteria remains challenging. The ARMYDA FINISH multicenter study evaluated whether indexing intravascular ultrasound (IVUS)‐derived minimum lumen area (MLA) provides greater diagnostic accuracy than unindexed MLA for detecting ...

The Utilization of Superficial Femoral Artery Access for Transcatheter Aortic Valve Replacement and Peripheral Vascular Interventions: A Systematic Review and Meta‐Analysis

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT The superficial femoral artery (SFA) is a vascular access alternative for various cardiovascular interventions, especially when the common femoral artery CFA is deep, calcified or in high bifurcation. SFA use, however, was associated with pseudoaneurysms in older literature, and its utilization for large‐bore access is not well established. We

Family Dynamics, Human Resource Practices and the Performance of Family Firms

Canadian Journal of Administrative Sciences / Revue Canadienne des Sciences de l'Administration, EarlyView.
ABSTRACT This study explores the impact of formalizing human resource (HR) practices on the performance of family firms. It also examines how family involvement in ownership and management, along with the presence of family employees, moderates this relationship.
