Diffuseness of coronary artery disease impacts on immediate hemodynamic and predicted clinical outcomes.
Sci Rep
January 2025
Department of Cardiology, University of Galway, University Road, Galway, H91 TK33, Ireland.
Diffuse coronary artery disease (CAD) impacts the immediate hemodynamic and clinical outcomes of percutaneous coronary intervention (PCI). We evaluated whether the diffuse pattern of CAD derived from angiographic Quantitative flow ratio (QFR) impacts the immediate hemodynamic outcome post-PCI and the medium term predicted vessel-oriented composite endpoint (VOCE). Paired pre-procedure QFRs were assessed in 503 patients and 1022 vessels in the Multivessel TALENT (MVT) trial.

Background: Thrombus enhancement sign (TES) has emerged as a potential imaging biomarker in patients with acute ischemic stroke (AIS) undergoing endovascular thrombectomy (EVT).
Objective: To evaluate the prognostic value of TES on 90-day mortality and functional outcomes.
Methods: We conducted a prospective, two-center study involving 323 patients with AIS treated with EVT.
Feasibility of on-site CT-FFR analysis on cardiac photon-counting CT in evaluation of hemodynamically significant stenosis in comparison to invasive catheter angiography.

Objectives: Coronary CT angiography (CCTA) is an excellent tool in ruling out coronary artery disease (CAD) but tends to overestimate especially highly calcified plaques. To reduce diagnostic invasive catheter angiographies (ICA), current guidelines recommend CT-FFR to determine the hemodynamic significance of coronary artery stenosis. Photon-Counting Detector CT (PCCT) revolutionized CCTA and may improve CT-FFR analysis in guiding patients.

This case highlights the prompt use of cardiac computer tomography angiography in a patient with intracardiac localization of diffuse large B-cell lymphoma and chest pain in the acute setting. Information on anatomical associations of the metastases with the coronaries serves as the foundation for subsequent therapeutic and diagnostic strategies.

Department of Radiological and Hematological Sciences, Section of Radiology, Università Cattolica del Sacro Cuore, Largo Agostino Gemelli 8 - 00168 Rome, Italy.
Background: Cardiac strangulation (CS) from epicardial pacing leads (EPLs) is a rare and potentially lethal mechanical complication associated with epicardial pacemaker (PM) implantation.
Case Summary: We report a case of a 44-year-old-female patient presenting with chest and left shoulder pain in the absence of reported trauma with history of congenital atrioventricular block treated with epicardial PM implantation during the childhood and subsequent transvenous reimplantation over the years. Troponin I resulted within normal values and ECG, transthoracic echocardiography and chest X-ray documented no acute cardiopulmonary findings.
