Highly effective adsorbents, with their impressive adsorption capacity and outstanding selectivity, play a pivotal role in technologies such as carbon capture and utilization in industrial flue gas applications, leading to significant reductions in greenhouse gas emissions. This study aims to synthesize advanced composites via solvothermal methods, incorporating a defective Zirconium-based MOF and amine-functionalized graphene oxide. The main objective is to enhance the CO adsorption capacity of the composite and improve its CO/N separation selectivity.

Importantly, the functionality of these dyes defines the ultimate application. Herein, CsPbBr perovskite nanocrystals (NCs) are interfaced with zinc phthalocyanine (ZnPc) dyes featuring carboxylic acid.

Coronary physiology assessment (CPA) is a guideline proven method to assess and diagnose these patients for an effective treatment strategy. There is currently no data regarding optimal wire or sensor position for CPA using bolus coronary thermodilution.

Advanced CKD patients often present with atypical symptoms, and conventional diagnostic and interventional approaches carry risks, including contrast-induced nephropathy and the potential need for renal replacement therapy. These risks have led to the phenomenon of "renalism," where necessary procedures may be deferred due to concerns over renal injury.

Introduction: The heart team approach is now the standard of care for patients with complex coronary artery disease; however, the definition of a heart team is variable. We embarked on a project to create an extended, multidisciplinary heart team to evaluate patients we deemed high risk for coronary revascularization. In doing so, we created a new service, workflow, and paradigm.

As a result, the vibrational spectra of the DNA-water-salt systems were calculated within the framework of two approaches, using dipole-dipole and velocity-velocity autocorrelation functions. We dissect the effect of the individual compartments of the DNA double helix (minor groove, major groove, and phosphate groups) on the behavior of the systems.

ST-elevation myocardial infarction (STEMI) remains a leading cause of morbidity and mortality in the United States. Timely reperfusion with primary percutaneous coronary intervention is associated with improved outcomes. The Society for Cardiovascular Angiography & Interventions puts forth this expert consensus document regarding best practices for cardiac catheterization laboratory team readiness, arterial access with an algorithm to help determine proper arterial access in STEMI, and diagnostic angiography.

Previous studies demonstrate comparable results assessing epicardial ischemia by fractional flow reserve using intravenous (IV) or intracoronary (IC) adenosine. It is unknown if there is a similarity between IC and IV hyperemia with adenosine when performing coronary reactivity testing (CRT).

Background: Percutaneous mitral balloon commissurotomy (PMBC) is the gold standard for the treatment of patients with symptomatic rheumatic mitral valve (MV) stenosis and favorable valve morphology. Intracardiac ultrasound (ICE)-guided PMBC is an attractive alternative to standard transesophageal echocardiography guidance for simplification of procedure and avoiding general anesthesia.
Methods: We conducted a retrospective analysis of all ICE-guided PMBC cases at our institution between July 2020 and November 2023.
Data on the long-term outcomes of prosthesis patient mismatch (PPM) after transcatheter aortic valve implantation (TAVI) remain controversial. This study aimed to investigate the incidence and clinical outcomes of measured PPM (PPM) and predicted PPM (PPM) in patients who underwent TAVI. This is a retrospective analysis of 3,016 patients who underwent TAVI at a large health care system between 2012 and 2021.

Background: A prior Society of Thoracic Surgeons/American College of Cardiology TVT (Transcatheter Valve Therapy) Registry-based analysis reported similar 1-year clinical outcomes with small (20-mm) vs large (≥23-mm) balloon-expandable valves (BEV).
Objectives: The aim of this study was to describe mid-term 3-year clinical outcomes for small vs large BEV and the relationship between discharge echocardiographic mean gradient (MG) and different definitions of prothesis-patient mismatch (PPM) with clinical outcomes.
Methods: Using the TVT Registry with Centers for Medicare and Medicaid Services linkage, a propensity-matched analysis of patients receiving 20- vs ≥23-mm BEVs was performed.
Valve-in-valve (ViV) transcatheter aortic valve replacement (TAVR) has been associated with favorable outcomes in patients with degenerated stentless bioprosthesis. However, whether the outcomes after ViV TAVR for failed stentless bioprosthesis differ between balloon-expandable valves (BEVs) and self-expanding valves (SEVs) remains unknown. Therefore, we retrospectively analyzed 59 consecutive patients who underwent ViV TAVR for failed stentless bioprsothesis with BEVs (n = 42) versus SEVs (n = 17) in a single-health care system between 2013 and 2022.
