Predictive value of the Naples prognostic score for no-reflow phenomenon after saphenous vein graft stenting.

Background: No-reflow is a critical adverse event associated with percutaneous coronary intervention (PCI), particularly during saphenous vein graft (SVG) procedures. The Naples Prognostic Score (NPS) reflects inflammatory status, but its relationship with no-reflow remains unclear. Therefore, we aimed to evaluate the relationship between NPS and no-reflow occurrence following SVG PCI.

Association of wide pulse pressure with coronary collateral flow in patients with ST-elevation myocardial infarction undergoing percutaneous coronary intervention.

Coronary collateral flow (CCF) is crucial for myocardial viability in patients with obstructive coronary artery disease, specifically ST-elevation myocardial infarction (STEMI). However, hypertension can contribute to vascular dysfunction and hinder the formation of CCF. Wide pulse pressure (WPP), defined as ≥65 mmHg, may better reflect impaired cardiovascular health compared to classic blood pressure indices.

Pangolin-inspired untethered magnetic robot for on-demand biomedical heating applications.

Untethered magnetic miniature soft robots capable of accessing hard-to-reach regions can enable safe, disruptive, and minimally invasive medical procedures. However, the soft body limits the integration of non-magnetic external stimuli sources on the robot, thereby restricting the functionalities of such robots. One such functionality is localised heat generation, which requires solid metallic materials for increased efficiency.

Magnetic guidewire steering at ultrahigh magnetic fields.

With remote magnetic steering capabilities, magnetically actuated guidewires have proven their potential in minimally invasive medical procedures. Existing magnetic steering strategies, however, have been limited to low magnetic fields, which prevents the integration into medical systems operating at ultrahigh fields (UHF), such as magnetic resonance imaging (MRI) scanners. Here, we present magnetic guidewire design and steering strategies by elucidating the magnetic actuation principles of permanent magnets at UHF.

The Systemic Immune-Inflammation Index and Predicting Cardiac Implantable Electronic Device Infections.

We recorded CIED infections and risk factors according to the patient, device, and procedural characteristics during the median 28.

Wireless MRI-Powered Reversible Orientation-Locking Capsule Robot.

Magnetic resonance imaging (MRI) scanners do not provide only high-resolution medical imaging but also magnetic robot actuation and tracking. However, the rotational motion capabilities of MRI-powered wireless magnetic capsule-type robots have been limited due to the very high axial magnetic field inside the MRI scanner. Medical functionalities of such robots also remain a challenge due to the miniature robot designs.

Heat-Mitigated Design and Lorentz Force-Based Steering of an MRI-Driven Microcatheter toward Minimally Invasive Surgery.

Catheters integrated with microcoils for electromagnetic steering under the high, uniform magnetic field within magnetic resonance (MR) scanners (3-7 Tesla) have enabled an alternative approach for active catheter operations. Achieving larger ranges of tip motion for Lorentz force-based steering have previously been dependent on using high power coupled with active cooling, bulkier catheter designs, or introducing additional microcoil sets along the catheter. This work proposes an alternative approach using a heat-mitigated design and actuation strategy for a magnetic resonance imaging (MRI)-driven microcatheter.
