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 ...

Tunable Regional Targeting of Self‐Assembling Peptide Nanomaterials in Acute Myocardial Infarction

Advanced NanoBiomed Research, EarlyView.
In a rat model of acute myocardial infarction, intravascular delivery of peptide nanofibers with a collagen‐targeting peptide bound to the infarct vasculature while globular peptide nanoparticles penetrated into the infarct area. This study demonstrated that size, shape, and surface chemistry of nanomaterials control the delivery location within the ...

Validation of the European Society of Cardiology Ischemic and Bleeding Risk Criteria for Risk Stratification After Endovascular Therapy in Japanese Patients With Lower Extremity Artery Disease

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The European Society of Cardiology (ESC) guidelines for peripheral artery disease recommend antithrombotic strategies based on high ischemic risk (HIR) and high bleeding risk (HBR) criteria. However, their prognostic value in patients with lower extremity artery disease (LEAD) undergoing endovascular therapy (EVT) remains unclear ...

Consecutive Emergency Carotid Artery Stenting and Transcatheter Aortic Valve Replacement in a Patient With Cardiogenic Shock: A Case Report

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Severe aortic stenosis (AS) carries a poor prognosis when symptomatic, particularly in cardiogenic shock (CS). Emergency transcatheter aortic valve replacement (TAVR) is rarely performed but may represent a rescue therapy. Coexistent carotid artery stenosis (CAS) further increases procedural risk.

Calcified Plaque Detachment: Alternative Calcified Plaque Modification After Coronary Intravascular Lithotripsy

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Calcified plaque (CP) detachment (CD) and calcium fracture (CF) can occur following coronary intravascular lithotripsy (IVL). The extent to which CF alone facilitates stent expansion during CP modification with IVL remains unclear. Aims This study aimed to investigate the clinical implications of IVL‐induced CD.

Coronary Perforation During Excimer Laser Angioplasty in a Patient With Prior Thoracic Radiotherapy

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Management of heavily calcified coronary lesions remains challenging despite advances in plaque‐modifying technologies. Excimer laser coronary angioplasty (ELCA) is an effective adjunctive strategy with a low risk of no‐reflow. Case Summary A 75‐year‐old woman with non–ST‐segment elevation acute coronary syndrome and severe left ...

Sheath‐to‐Artery Diameter Ratio: A Robust Predictor of Early Access‐Site Adverse Events in Percutaneous Procedures

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Vascular access site complications (VASCs) remain an important source of morbidity following percutaneous interventions. Although the sheath‐to‐femoral artery ratio is a recognized risk factor in transcatheter aortic valve implantation (TAVI), its role across a broader range of femoral procedures is less well defined.

Bilateral renal artery stenosis treated with drug-eluting balloon angioplasty in unique treatment

Radiology Case Reports, 2019
Renal artery stenosis commonly manifests with hypertension refractory to medical treatment. We report a case of renal artery stenosis occurring in a 19-year-old female patient who presented with extremely high blood pressure and bilateral renal stenosis ...
