Article Abstract
Purpose: We prospectively assessed the ability of a novel transurethral catheterization safety valve to prevent urethral catheter balloon injury in a multi-institutional clinical setting.
Materials And Methods: A prospective, multi-institution study was conducted. The safety valve was introduced for urinary catheterization in 6 hospital groups (4 in Ireland; 2 in the UK). The safety valve allows fluid in the catheter system to vent through a pressure relief valve if attempted intraurethral inflation of the catheter's anchoring balloon occurs. Device usage was studied over a 12-month period, with data recorded using a 7-item data sticker containing a scannable QR code. "Venting" through the safety valve during catheterization was indicative of prevention of a urethral injury. An embedded 3-month study was conducted in 3 centers, with any catheter balloon injuries occurring during catheterization without safety valve use referred to the on-call urology team recorded. Health economic analyses were also performed.
Results: During the overall 12-month device study phase, 994 urethral catheterizations were performed across study sites. Twenty-two (2.2%) episodes of safety valve venting were recorded. No urethral injuries occurred in these patients. In the embedded 3-month study, 18 catheter balloon injuries were recorded in association with catheterizations performed without the safety valve. Based on confirmed and device-prevented urethral injuries, the injury rate for urethral catheterization without safety valve use was calculated to be 5.5/1,000 catheterizations.
Conclusions: The safety valve has the potential to eliminate catheter balloon injury if widely adopted. It represents a simple, effective, and innovative solution to this recurring problem applicable to all patient cohorts.

Introduction And Objectives: The Valve Academic Research Consortium (VARC)-3 definition of the early safety (ES) composite endpoint after transcatheter aortic valve replacement (TAVR) lacks clinical validation. The aim of this study was to determine the incidence, predictors, and clinical impact of ES after TAVR as defined by VARC-3 criteria.
Methods: We performed a multicenter study including 10 078 patients with severe aortic stenosis undergoing transarterial TAVR.

Introduction: Mitral Valve Transcatheter Edge-to-Edge Repair (M-TEER) is a minimally invasive procedure for patients with symptomatic mitral regurgitation. Its outcomes in patients with a history of coronary artery bypass grafting (CABG) remain unclear.
Methodology: We analyzed data from the Nationwide Inpatient Sample, using ICD-10-CM codes for M-TEER and CABG.

Water hammer (WH) is a phenomenon characterized by the rapid opening or closing of valves or pumps in pipelines, resulting in a disruptive noise, intense vibrations, and potential damage to pipes, fittings, structures, and even human safety. While WH arresters are commonly employed to mitigate this issue in smaller plumbing systems, alternative solutions are required for larger applications like power plants. Researchers have proposed the utilization of pipe materials with a low modulus of elasticity in areas prone to WH events, as these materials possess the capability to absorb a significant portion of the resulting vibrations.

Background: The introduction of transcatheter procedures has focused on patient expectations for treatments with a less invasive approach and faster recovery. The aim of this study was to assess the short- and medium-term results in patients who underwent trans-axillary mitral valve repair with application of the ultra-fast-track protocol.
Methods: Data from 431 patients undergoing isolated trans-axillary mitral valve repair or associated with tricuspid valve treatment between January 2018 and December 2023 were prospectively collected.
