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.

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 ...

Balloon‐Stopper Retrieval and Peripheral Parking After Inadvertent Ostial Right Coronary Stent Deployment

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Percutaneous treatment of right coronary artery (RCA) ostial lesions is technically challenging due to cardiorespiratory motion. Case Summary We describe a 70‐year‐old man undergoing PCI for an ostial RCA lesion where a forceful cough caused complete stent expansion within the aortic root.

Diagnostic Agreement and Threshold Correspondence Between Resting Full‐Cycle Ratio and Nicorandil‐Based Fractional Flow Reserve in Intermediate Coronary Stenosis: A Prospective Single‐Center Registry

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background RFR has shown good aggregate agreement with FFR, including in prior Asian cohorts using intracoronary nicorandil. Where RFR‐FFR disagreement is concentrated relative to the FFR 0.80 decision boundary, and how the two binary thresholds correspond, remain incompletely characterized. Methods In a prospective single‐center registry, 300

Cangrelor Dosing, Administration, and Clinical Outcomes for Patients Undergoing Complex and High‐Risk Percutaneous Coronary Interventions

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Cangrelor reduces thrombotic events in patients undergoing percutaneous coronary intervention (PCI), with the advantage of rapid onset and offset. However, premature discontinuation may increase the risk of acute thrombosis for patients undergoing complex/high‐risk PCI (CHIP).

From Biological Mechanisms to Causal Inference: Quantitative Systems Pharmacology and Causal Frameworks in Drug Development

Clinical Pharmacology &Therapeutics, EarlyView.
Digital patients and in silico clinical trials offer new opportunities to advance pharmacological research, clinical development, and regulatory decision‐making by enabling the simulation of treatment effects prior to testing in patients. Among the most promising of these opportunities is the combined use of quantitative systems pharmacology (QSP) and ...

Thermal Conduction in Laser‐Driven Tin Plasmas and the Sensitivity of Plasma Properties to the Flux Limiter

Contributions to Plasma Physics, EarlyView.
ABSTRACT We study the role of thermal conduction in laser‐produced tin plasma sources of extreme ultraviolet (EUV) light using radiation‐hydrodynamic simulations. Adopting the flux‐limited Spitzer–Härm approach, we investigate the sensitivity of the electron temperature, electron density, net in‐band emissivity, and conversion efficiency to the choice ...
