Effects of Guiding Catheter on FFR and NHPR for the Assessment of Coronary Artery Stenoses (Disengage@Rest) (Disengage@Rest)

February 22, 2024 updated by: Giovanni Esposito, Federico II University

Effects of Guiding Catheter on Fractional Flow Reserve and Non-Hyperemic Pressure Ratios for the Assessment of Coronary Artery Stenoses - Disengage @Rest

The DISENGAGE@rest study is a prospective registry carried out at Federico II University of Naples with the aim to evaluate the influence of the guiding catheter engagement within the coronary ostium on both FFR and non-hyperaemic pressure ratios values (such as Pd/Pa and the Resting Full-cycle Ratio -RFR), as well as the corresponding clinical impact on decision-making strategies. Consecutive patients with at least one intermediate stenosis (40%-90% by visual estimation) in any of the 3 main coronary arteries will be included.
