Frontiers in Cardiovascular Medicine, 2023 BackgroundAccelerated stenotic flow (AsF) in the entire left anterior descending coronary artery (LAD), assessed by transthoracic enhanced color Doppler (E-Doppler TTE), can reveal coronary stenosis (CS) and its severity, enabling a distinction between ...

The Value of Intracoronary Imaging and Coronary Physiology When Treating Calcified Lesions
Interventional Cardiology: Reviews, Research, Resources, 2019 Heavily calcified coronary artery lesions hinder the delivery of devices and limit stent expansion, resulting in low procedural success and poor clinical outcomes driven by an increase in restenosis and stent thrombosis.

Comparison of Resting Full-Cycle Ratio and Fractional Flow Reserve in a German Real-World Cohort
Frontiers in Cardiovascular Medicine, 2021 Objective: The aim of this study was to evaluate non-hyperemic resting pressure ratios (NHPRs), especially the novel “resting full-cycle ratio” (RFR; lowest pressure distal to the stenosis/aortic pressure during the entire cardiac cycle), compared to the

Advances in Coronary Physiology
Circulation Journal, 2015 Pressure-wire technology, most typically fractional flow reserve (FFR), has provided interventional cardiologists with a means of determining the physiological importance of a stenosis during angiography. There has been renewed interest in coronary physiology in the light of guideline recognition, ongoing clinical research and new technologies changing

Why, When and How Should Clinicians Use Physiology in Patients with Acute Coronary Syndromes?
Interventional Cardiology: Reviews, Research, Resources, 2020 Current data support the use of coronary physiology in patients with acute coronary syndrome (ACS). In patients with ST-elevation MI, the extent of myocardial damage and microvascular dysfunction create a complex conundrum to assimilate when considering ...
