Impact of Right Atrial Pressure on Fractional Flow Reserve Measurements

JACC: Cardiovascular Interventions, 2016
This study sought to assess the impact of a wide range of mean right atrial pressure (Pra) on fractional flow reserve (FFR) measurements.FFR invasively assesses the ischemic potential of coronary stenoses. FFR is calculated as the ratio of mean distal coronary pressure (Pd) to mean aortic pressure (Pa) during maximal hyperemia. The Pra is considered to

Fractional flow reserve of non-culprit vessel post-myocardial infarction: is it reliable? [PDF]

BMC Cardiovascular Disorders, 2015
Multi-vessel disease is frequent in patients presenting with myocardial infarction and have an important prognostic impact. The decision to proceed to revascularization in non-culprit vessels can be postponed until ischemia is proven in non-invasive stress tests.

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 ...

Fractional Flow Reserve in Acute Myocardial Infarction: A Guide for Non-Culprit Lesions? [PDF]

Cardiology and Therapy, 2015
In patients presenting with ST-segment elevation myocardial infarction (STEMI) and multi-vessel disease (MVD), the optimal therapy for non-culprit lesions is still a matter of debate. While guidelines discourage a concomitant treatment of infarct- and non-infarct-related arteries, recent studies document advantages of a complete (preventive ...

Biomarkers of coronary endothelial health: correlation with invasive measures of collateral function, flow and resistance in chronically occluded coronary arteries and the effect of recanalization [PDF]

, 2016
Objectives: In the presence of a chronically occluded coronary artery, the collateral circulation matures by a process of arteriogenesis; however, there is considerable variation between individuals in the functional capacity of that collateral network ...

The Impact of Myocardial Bridging on Fractional Flow Reserve

, 2022
Arterial stenosis is a problem of immediate significance, as cardiovascular disease is the number one leading cause of death worldwide. Fractional flow reserve (FFR) was proposed to evaluate the functional severity of coronary plaque-induced stenosis more accurately. FFR relies on invasive pressure measurements, while computational fluid dynamics (CFD)
