Prior SARS‐CoV‐2 Infection Is Associated With Coronary Vasomotor Dysfunction as Assessed by Coronary Flow Reserve From Cardiac Positron Emission Tomography [PDF]

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2022
Background Cardiovascular complications from COVID‐19 contribute to its high morbidity and mortality. The effect of COVID‐19 infection on the coronary vasculature is not known.

Continuous Versus Bolus Thermodilution‐Derived Coronary Flow Reserve and Microvascular Resistance Reserve and Their Association With Angina and Quality of Life in Patients With Angina and Nonobstructive Coronaries: A Head‐to‐Head Comparison [PDF]

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
Background Coronary flow reserve (CFR) and microvascular resistance reserve (MRR) are physiological parameters to assess coronary microvascular dysfunction. CFR and MRR can be assessed using bolus or continuous thermodilution, and the correlation between

To Explore the Influencing Factors of Pericoronary Adipose Tissue and Noninvasive Fractional Flow Reserve on the Progression of Coronary Heart Disease Based on 320-Slice Coronary CTA

Anatolian Journal of Cardiology, 2023
Background: The objective of the study was to measure pericoronal adipose tissue parameters, fractional flow reserve with coronary artery computed tomographic angiography (CTA), and difference of fractional flow reserve with coronary artery CTA, by using

Structure (Epicardial Stenosis) and Function (Microvascular Dysfunction) That Influence Coronary Fractional Flow Reserve Estimation

Applied Sciences, 2022
Background. The treatment of coronary stenosis is decided by performing high risk invasive surgery to generate the fractional flow reserve diagnostics index, a ratio of distal to proximal pressures in respect of coronary atherosclerotic plaques.

Prognostic Implications of Resistive Reserve Ratio in Patients With Coronary Artery Disease

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Resistive reserve ratio is a thermodilution‐based index which integrates both coronary flow and pressure. Resistive reserve ratio represents the vasodilatory capacity of interrogated vessels including both epicardial coronary artery and ...

Intravascular Imaging versus Physiological Assessment versus Biomechanics—Which Is a Better Guide for Coronary Revascularization

Diagnostics, 2023
Today, coronary artery disease (CAD) continues to be a prominent cause of death worldwide. A reliable assessment of coronary stenosis represents a prerequisite for the appropriate management of CAD.

Coronary flow reserve and microcirculatory resistance in patients with coronary tortuosity and without atherosclerosis

Journal of International Medical Research, 2020
Objective Coronary tortuosity may affect epicardial coronary arterial blood flow. This study aimed to investigate the effect of coronary tortuosity on coronary flow reserve and the coronary microcirculation in patients without apparent coronary ...

Reduced coronary flow reserve in Anderson-Fabry disease measured by transthoracic Doppler echocardiography

Cardiovascular Ultrasound, 2005
Coronary flow reserve was assessed in a patient with Anderson-Fabry disease complicated by symmetric left ventricular hypertrophy. Coronary flow reserve was measurable in all three major coronary arteries providing an opportunity to compare regional ...

What is the Role of Coronary Physiology in the Management of Patients with Chronic Coronary Syndromes?

Reviews in Cardiovascular Medicine, 2022
The use of coronary physiology in patients with chronic coronary syndromes is highly variable, and the evidence base complex. Tests of coronary physiology have traditionally been invasive (e.g., fractional flow reserve), but novel non-invasive methods ...
