Endovascular Treatment of Malfunctioning Dialysis Fistulas: A Multicenter Retrospective Analysis Comparing Transradial and Conventional Transvenous Access

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Venous outflow is the favored access for endovascular management of dialysis fistulas. However, transradial access (TRA) offers advantages in specific clinical scenarios. The study aims to compare the efficacy, feasibility, and safety of TRA and transvenous access (TVA) in the endovascular management of malfunctioning dialysis ...

Novel Transthoracic Pulmonary Valve Implantation Using Self‐Expanding Salus Valve: A Prospective Study of Safety and Mid‐Term Outcomes

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter pulmonary valve replacement (TPVR) has emerged as a valuable treatment for severe pulmonary regurgitation (PR). The Salus valve (Balance Medical Technology Co. Ltd., Beijing, China) represents a novel self‐expanding valve stent designed for deployment through a transthoracic approach with a small subxiphoid incision ...

Delay-Doppler Multiplexing With Global Filtering [PDF]

arXiv
This paper proposes a novel modulation technique called globally filtered orthogonal time frequency space (GF-OTFS) which integrates single-carrier frequency division multiple access (SC-FDMA)-based delay-Doppler representation with universal filtered multi-carrier (UFMC) modulation.

Safety and Efficacy of Single Femoral Vein Puncture Technique for Double Access in Patent Foramen Ovale Closure Under ICE Guidance—A Single Center Experience of the “Two‐In‐One Technique”

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background In selected patient populations, percutaneous closure of patent foramen ovale has been shown to be beneficial in preventing cerebral ischaemic events. In most cases, this procedure requires echocardiographic guidance, which may be transesophageal, transthoracic or intracardiac.
