Factors associated with early and late losses of primary patency following drug-coated balloon for dysfunctional arteriovenous fistula.
J Vasc Access
January 2025
Department of Internal Medicine, Division of Kidney and Dialysis, Kansai Rosai Hospital, Amagasaki, Japan.
Objective: This study aimed to evaluate the effectiveness of a drug-coated balloon (DCB) for the treatment of dysfunctional arteriovenous fistulas (AVFs) and to identify the risk factors associated with early and late losses of primary patency following DCB in real-world practice.
Methods: This multicenter, retrospective study included 407 patients (72 ± 11 years, 64.1% males) with dysfunctional AVFs (juxta-anastomotic lesion location in 58.
A Belgian physician-initiated trial investigating the LifeStream peripheral stent graft system for the treatment of complex TASC C and D iliac lesions.
J Cardiovasc Surg (Torino)
February 2025
Department of Vascular Surgery, AZ Sint Blasius, Dendermonde, Belgium.
Background: Due to the heterogeneity of literature findings, stent type selection for the endovascular treatment of complex aorto-iliac occlusive disease remains challenging. The BELSTREAM study, a physician-initiated, prospective, multicenter, single-arm study, aims to report the safety and efficacy of the balloon expandable LifeStream Peripheral Stent Graft System (BD, Tempe, Arizona, USA) for the treatment of complex TASC C and D aorto-iliac artery lesions.
Methods: Seventy patients and 133 lesions were included at six Belgian institutions.
Optimizing the life of vascular access during follow-up.
J Cardiovasc Surg (Torino)
February 2025
Department of Vascular Surgery, ASST Settelaghi Universitary Teaching Hospital, University of Insubria, Varese, Italy.
Optimizing the longevity of vascular access in hemodialysis patients remains a critical aspect of patient care, given the significant role of arteriovenous fistulas (AVFs) and arteriovenous grafts (AVGs) in enabling effective dialysis. Vascular access complications, such as stenosis, thrombosis, and cannulation-related damage, continue to challenge both the functionality and the sustainability of these access points. Recent advancements underscore the importance of a robust follow-up strategy, integrating clinical evaluations with diagnostic tools like color Doppler ultrasound (CDU) and emerging interventional approaches such as drug-coated balloon (DCB) angioplasty.

Eur Heart J Case Rep
January 2025
Division of Cardiology, Department of Medicine, Kindai University Faculty of Medicine, 377-2 Ohno-Higashi, Osakasayama, Osaka 589-8511, Japan.
Background: The initial outcomes of transcatheter aortic valve replacement in patients with left ventricular outflow tract calcification are poor. Furthermore, balloon-expandable transcatheter aortic valve replacement is associated with an increased risk of annular rupture, and self-expandable transcatheter aortic valve replacement is associated with worse post-operative residual paravalvular leakage grades. Therefore, developing an optimal method for transcatheter aortic valve replacement for patients with left ventricular outflow tract calcification is desirable.

J Cardiothorac Surg
January 2025
Clinical Research Development Unit, Shafa Hospital, Kerman University of Medical Sciences, Kerman, Iran.
Background: This study aimed to investigate the major predictive factors associated with prolonged mechanical ventilation(PMV) following cardiac surgery.
Methods: This retrospective, cross-sectional, descriptive-analytical study was conducted from September 2021 to March 2022, involving 244 patients who underwent cardiac surgery. PMV was defined as mechanical ventilation for more than 24 h.
