The growth of coronary angioplasty has resulted in increased fluoroscopy time to patients, staff, and physicians. Rapid exchange-type catheters have purported to reduce fluoroscopy time and procedure time compared to conventional over-the-wire systems. Of 150 consecutive patients, 54 were treated solely with rapid-exchange catheters and 84 were treated solely with over-the-wire catheters. Excluding 12 cases treated with fixed wire or combination catheters, the following data were found: [table: see text] Overall procedural success was obtained in 98.5% (136/138) of patients, 1.5% (2) requiring emergency coronary artery bypass graft surgery. A significant 35% reduction in fluoroscopy time and 13% reduction in procedure time were found when rapid-exchange catheters were used, with identical success rates, number of balloons used per case, and complication rates compared to over-the-wire catheters. Rapid-exchange catheters should be considered as part of an overall effort to reduce radiation exposure in the interventional cardiology laboratory.

Lucerne milestone approach for benchmarking and education: Towards ultra-low dose endovascular aortic repair.
J Vasc Surg Cases Innov Tech
April 2025
Department of Radiology and Nuclear Medicine, University Teaching and Research Hospital Lucerne, Luzern, Switzerland.
Objective: The aim of this single-center case series is to demonstrate that an ultra-low dose (ULD) can be routinely achieved in the hybrid operating room in standard endovascular aortic repair (EVAR) for infrarenal abdominal aortic aneurysm by adjusting the manufacturer's predefined imaging parameters, hardware configurations and user protocols (including benchmarking).
Methods: The hybrid operating room manufacturer predefined EVAR software setup of the dose exposure control software (OPTIQ, Siemens Healthineers, Forchheim, Germany) at our university medical center was screened for possible improvements regarding radiation dose application. Tests on a water-equivalent as well as polymethyl methacrylate phantom model to assess the impact of technical settings were performed, including comparison of settings for exposure control software, different magnification, collimation configurations and detector distance.
Objective: This study aims to evaluate the clinical benefits of the integrated optical and magnetic surgical navigation system in assisting transforaminal endoscopic lumbar discectomy (TELD) for the treatment of lumbar disc herniation (LDH).
Methods: A retrospective analysis was conducted on patients who underwent TELD for LDH at our hospital from November 2022 to December 2023. Patients treated with the integrated optical and magnetic surgical navigation system were defined as the navigation-guided transforaminal endoscopic lumbar discectomy (Ng-TELD) group (30 cases), while those treated with the conventional X-ray fluoroscopy method were defined as the control group (31 cases).
Omnipolar mapping versus point-by-point mapping approach for catheter ablation of atrioventricular accessory pathway.
J Interv Card Electrophysiol
January 2025
Department of Cardiovascular Medicine, Dokkyo Medical University, 880 Kitakobayashi, Mibu, Shimotsugagun, Tochigi, 321-0293, Japan.
Background: The conventional mapping approach for the atrioventricular accessory pathway (AP) involves point-by-point mapping to identify the connection sites of the AP to the atria or ventricle and accurate interpretation of local electrograms. Omnipolar mapping technology (OMT) explains how vector and wave speed are produced by using both unipolar and bipolar signals to obtain omnipolar signals, directions, and conduction velocity. The aim of this study is to verify the effectiveness of OMT for catheter ablation of AP.

Quant Imaging Med Surg
January 2025
Department of Diagnostic Radiology, First Medical Center of the Chinese PLA General Hospital, Beijing, China.
Background: Traditional freehand puncture relies on non-real-time computed tomography (CT) images, which significantly affects the accuracy of puncturing targets in the lower lung lobes with respiratory motion. This study aims to assess the safety and feasibility of a teleoperated robotic system and low-dose CT for the accurate real-time puncture of targets in the lungs of live pigs during breathing under fluoroscopic guidance.
Methods: Two puncture methods were analyzed: freehand and robot-assisted.
Comparison of radiation exposure for interventional radiology vs urology-guided renal access for percutaneous nephrolithotomy.

Department of Urology, MedStar Georgetown, Georgetown University School of Medicine, 3900 Reservoir Rd NW, Washington, DC, 20007, USA.
Introduction: Radiation exposure during percutaneous nephrolithotomy (PCNL) can vary depending on the method used for renal access. This study aimed to compare fluoroscopy time and dose during PCNL when renal access is achieved via interventional radiology (IR) versus urology.
Methods: A retrospective review of patients who underwent unilateral PCNL between January 2020 and February 2023 was conducted.
