Thermally Drawn Bioelectric Catheters: Enabling Proprioceptive Endovascular Navigation

Advanced Intelligent Systems, EarlyView.
This work introduces a novel bioelectric navigation system eliminates the need for harmful fluoroscopy during endovascular surgeries. A bespoke 16‐electrode catheter is fabricated using rapid thermal drawing and laser micro‐machining. Paired with a real‐time tracking algorithm fusing vascular geometry detection and distance estimation, this technology ...

Identifying patients at high risk for post-EVAR aneurysm sac growth [PDF]

, 2023
Purpose: Post-EVAR (endovascular aneurysm repair) aneurysm sac growth can be seen as therapy failure as it is a risk factor for post-EVAR aneurysm rupture.

Feasibility and Procedural Considerations of Balloon‐Expandable TAVR in Patients With Prior Endovascular Aortic Stent Grafts

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Objectives To evaluate the feasibility and short‐term outcomes of transcatheter aortic valve replacement (TAVR) using balloon‐expandable Sapien valves in patients with prior endovascular aortic stent grafts. Methods We conducted a single‐center, retrospective study of 23 patients with prior endovascular aortic stent grafts who underwent TAVR ...

Comparison of 3‐Dimensional Ultrasound and Computed Tomography for Imaging of Abdominal Aortic Aneurysms

Journal of Ultrasound in Medicine, EarlyView.
Objectives Three‐dimensional ultrasound (3D US) is emerging as a novel imaging method for abdominal aortic aneurysms (AAAs) as it creates a low‐cost 3D AAA overview without harmful radiation and nephrotoxic contrast agents, as opposed to conventional imaging. 3D US can be used with a non‐nephrotoxic contrast agent (3D‐CEUS) for lumen delineation.

The Effects of Accounting Enforcement on the Informativeness of Capitalised R&D Across IFRS Countries

Accounting &Finance, EarlyView.
ABSTRACT We examine the effect of country‐level accounting enforcement on the informativeness of capitalised R&D across 19 countries that adopted IFRS by 2005. We find that capitalised R&D has a marginally stronger positive association with future earnings in strong‐enforcement countries compared to weak‐enforcement countries, consistent with higher ...

Reflected wave intensity increases based on aortic diameter after endovascular aortic therapy in a goat model

Scientific Reports, 2021
Reflected wave increases after endovascular aortic repair (EVAR) in patients with aortic aneurysm. This affects the left ventricular (LV) diastolic function and leads to a poor prognosis.

Fusion Imaging for EVAR with Mobile C-arm.

Annals of Vascular Surgery, 2019
BACKGROUND Fusion imaging is a technique that facilitates endovascular navigation but is only available in hybrid rooms. The goal of this study was to evaluate the feasibility of fusion imaging with a mobile C-arm in a conventional operating room through

Targeting PCSK9 in Vascular Smooth Muscle Cells: An Effective Strategy to Suppress Ferroptosis and Attenuate Abdominal Aortic Aneurysm Progression

Cell Proliferation, EarlyView.
PCSK9 aggravates AAA by promoting ferroptosis in VSMCs. In the pathological AAA environment, PCSK9 upregulation triggers ferritinophagy‐dependent degradation of FTH1, leading to Fe2+ release, triggering lipid peroxidation and ferroptosis, exacerbating AAA.
