Mechanical Circulatory Support With Impella in High-Risk Patients With Chronic Total Occlusion and Complex Multivessel Disease.
Catheter Cardiovasc Interv
January 2025
Cardiology Department, Reina Sofia University Hospital, Cordoba, Spain.
Background: The therapeutic management of patients with multivessel disease and severe left ventricular dysfunction is complex and controversial.
Aims: The aim of this study was to analyze the clinical outcomes and the changes in left ventricular ejection fraction (LVEF) in patients with severe left ventricular dysfunction and at least one chronic total occlusion (CTO) undergoing percutaneous coronary intervention (PCI) with hemodynamic support provided by Impella.
Methods: Retrospective, multicenter study enrolling patients with severe left ventricular dysfunction and severe coronary artery disease with at least one CTO who required percutaneous mechanical circulatory support with Impella, from January 2019 to December 2023.
Panoramic Nailfold Flow Velocity Measurement Method Based on Enhanced Plasma Gap Information.

January 2025
State Key Laboratory of Traditional Chinese Medicine Syndrome/Health Construction Center, The Second Affiliated Hospital of Guangzhou University of Chinese Medicine, Guangzhou, 510120, China.
Nailfold microcirculation examination is crucial for the early differential diagnosis of diseases and indicating their severity. In particular, panoramic nailfold flow velocity measurements can provide direct quantitative indicators for the study of vascular diseases and technical support to assess vascular health. Previously, nailfold imaging equipment was limited by a small field of view.
View Article and Find Full Text PDFAcute ST-elevation myocardial infarction (STEMI) is a life-threatening condition often associated with significant cardiac complications, particularly in the presence of underlying multivessel coronary artery disease. Mechanical complications, such as acute mitral regurgitation (MR), can worsen the clinical course, leading to rapid hemodynamic deterioration. Recent advancements in mechanical circulatory support and percutaneous interventions have introduced new therapeutic options, offering viable alternatives to traditional surgery for high-risk patients.
View Article and Find Full Text PDFBackground: Risk stratification of patients with symptomatic nonobstructive coronary artery disease remains uncertain. Our study assessed the clinical value of single-vessel, multivessel, and 3-vessel computational angiography-derived fractional flow reserve (caFFR) measurement in patients with nonobstructive coronary artery disease.
Methods And Results: We enrolled patients with ≤50% stenosis with a caFFR value ≥0.
Quantitative flow ratio of the donor coronary artery supplying a chronic total occlusion territory.
Clin Res Cardiol
December 2024
Cardiology Department, Heart Center Segeberger Kliniken GmbH, Am Kurpak 1, 23795, Bad Segeberg, Germany.
Background: Coronary physiology to guide multi-vessel coronary intervention is associated with better outcome. In the presence of a coronary chronic total occlusion (CTO), hemodynamic evaluation of intermediate lesions in the donor coronary artery supplying a CTO territory still has limitations. We aim to evaluate implementing quantitative flow ratio (QFR) in assessing angiographically intermediate lesions of the main donor coronary artery supplying a CTO territory.
