Mitochondrial Protection and Neural Repair via ROS‐Responsive Biomimetic Nanoparticles in Intracerebral Hemorrhage

Advanced Science, EarlyView.
A ROS‐responsive biomimetic nanoparticle platform co‐delivers DIDS and Mdivi‐1 to protect mitochondria and promote neural repair after intracerebral hemorrhage. By targeting LPAR1/VDAC1‐related mitochondrial dysfunction, the nanotherapy reduces oxidative injury, neuronal apoptosis, and blood‐brain barrier disruption, improving neurological recovery and

Morphometric analysis of heparin coated versus standard intra-aortic balloons

, 1998
The adverse effects of systemic heparin administration has led to the development of heparin coated devices. Intra-aortic balloons are frequently used in clinical settings in which complications of systemic heparin, especially bleeding, are feared.

Implantable Systems for Cardiovascular Treatment and Monitoring: Comparative Insights From Intracardiovascular and Extracardiovascular Technologies

Advanced Intelligent Systems, EarlyView.
A unifying device–cardiovascular interface framework is presented to classify implantable cardiovascular technologies as intracardiovascular blood‐contacting systems or extracardiovascular tissue‐only and blood‐handling architectures. Cross‐class comparison across shared semiquantitative criteria, including blood‐contact burden, biomimicry ...

When Subtle Guiding Catheter‐Induced Stent Deformation Leads to Abluminal Guidewire Passage: Successful IVUS Tip‐Detection‐Guided Bailout

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Incomplete stent apposition at the proximal coronary artery may predispose to subtle guiding catheter–induced stent deformation, creating a gap between the stent and the vessel wall that facilitates inadvertent abluminal guidewire passage. We report a case in which balloon dilatation over an unrecognized abluminal guidewire resulted in severe ...

Mechanisms and Management of Acquired Aseptic Intracardiac Communications After Transcatheter Aortic Valve Implantation: Single‐Center Case Series Insights

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Acquired aseptic intracardiac communications (AICCs) are rare but clinically relevant structural complications following transcatheter aortic valve implantation (TAVI), typically resulting from mechanical injury to the aortic annulus, interventricular septum, or adjacent structures.

Intravascular Lithotripsy in Left Main Stem Percutaneous Coronary Intervention

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background IVL is increasingly used for coronary calcium modification; however, prospective data for its use in LMS lesions are lacking. Aims To evaluate the feasibility, safety, and mechanical efficacy of intravascular lithotripsy (IVL) for calcium modification in calcified distal left main stem (LMS) percutaneous coronary intervention ...

Biventricular Pressure‐Volume Loop Analysis in an LVAD Patient Optimized With Impella RP Flex

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Right ventricular (RV) failure after left ventricular assist device (LVAD) implantation is a serious complication which may necessitate temporary mechanical support in refractory cases. Here we describe a 63‐year‐old man with end‐stage ischemic cardiomyopathy and severe combined pre‐ and post‐capillary pulmonary hypertension who developed ...

External Validation of the UK‐BCIS CHIP Score to Predict 1‐Year Outcomes in Patients Undergoing IVL‐Assisted PCI: Insights From the International BENELUX‐IVL Registry

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The United Kingdom–British Cardiovascular Intervention Society complex high‐risk indicated percutaneous coronary intervention (UK‐BCIS CHIP) score was developed to identify patient‐ and procedural factors to predict short‐term adverse outcomes in patients undergoing high risk percutaneous coronary intervention (PCI). The performance

Intra-aortic balloon pump does not influence cerebral hemodynamics and neurological outcomes in high-risk cardiac patients undergoing cardiac surgery: an analysis of the IABCS trial

, 2019
The intra-aortic balloon pump (IABP) is often used in high-risk patients undergoing cardiac surgery to improve coronary perfusion and decrease afterload. The effects of the IABP on cerebral hemodynamics are unknown.
