Coronary Flow Velocity Reserve and Survival

open access: yesJACC: Cardiovascular Imaging, 2012
Almost 40 years ago, K. Lance Gould proposed the concept of coronary flow reserve (CFR) to quantify the effect of epicardial narrowings on myocardial blood flow ([1][1]). CFR represents the extent to which hyperemic coronary flow can increase above resting flow.

A randomized, placebo-controlled trial of late Na current inhibition (ranolazine) in coronary microvascular dysfunction (CMD): impact on angina and myocardial perfusion reserve. [PDF]

open access: yes, 2015
AimsThe mechanistic basis of the symptoms and signs of myocardial ischaemia in patients without obstructive coronary artery disease (CAD) and evidence of coronary microvascular dysfunction (CMD) is unclear.

Significance of Microvascular Function in Visual—Functional Mismatch Between Invasive Coronary Angiography and Fractional Flow Reserve

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017
BackgroundDespite a moderate correlation between angiographical stenosis and physiological significance, the mechanism of discordance has not been fully elucidated, particularly regarding the significance of microvascular function.

Coronary Thermodilution to Assess Flow Reserve [PDF]

open access: yesCirculation, 2001
Background Fractional flow reserve (FFR) and coronary flow reserve (CFR) are indices of coronary stenosis severity that provide the clinician with complementary information on the contribution of epicardial arteries and ...

Microvascular dysfunction in the immediate aftermath of chronic total coronary occlusion recanalization [PDF]

open access: yes, 2016
Objectives The aim of this study was to compare microvascular resistance under both baseline and hyperemic conditions immediately after percutaneous coronary intervention (PCI) of a chronic total occlusion (CTO) with an unobstructed reference vessel in ...

Quantitative assessment of harmonic power doppler myocardial perfusion imaging with intravenous levovist™ in patients with myocardial infarction: comparison with myocardial viability evaluated by coronary flow reserve and coronary flow pattern of infarct-related artery

open access: yesCardiovascular Ultrasound, 2005
Background Myocardial contrast echocardiography and coronary flow velocity pattern with a rapid diastolic deceleration time after percutaneous coronary intervention has been reported to be useful in assessing microvascular damage in patients with acute ...

Coronary flow reserve assessment

open access: yesEuropean Heart Journal, 2005
We would like to add some comments to an interesting paper of Voci et al. 1 Apart from the anterior and posterior descending coronary artery, it is possible to visualize transthoracically proximal and middle segments of the circumflex coronary artery and all three segments of the right coronary artery.2–5 The images other than from the apical windows ...

The haemodynamic effects of collateral donation to a chronic total occlusion : implications for patient management [PDF]

open access: yes, 2015
Physiological lesion assessment in the form of Fractional Flow Reserve (FFR) is now well established for the purpose of guiding multi-vessel revascularization.

Impact of Asymptomatic Intracranial Hemorrhage on Outcome After Endovascular Stroke Treatment

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Endovascular treatment (EVT) achieves high rates of recanalization in acute large‐vessel occlusion (LVO) stroke, but functional recovery remains heterogeneous. While symptomatic intracranial hemorrhage (sICH) has been well studied, the prognostic impact of asymptomatic intracranial hemorrhage (aICH) after EVT is less certain ...

Robust Association Between Changes in Coronary Flow Capacity Following Percutaneous Coronary Intervention and Vessel-Oriented Outcomes and the Implication for Clinical Practice

open access: yesFrontiers in Cardiovascular Medicine, 2022
BackgroundCoronary flow capacity (CFC) is a potentially important physiologic marker of ischemia for guiding percutaneous coronary intervention (PCI) indication, while the changes through PCI have not been investigated.ObjectivesTo assess the ...
