Effect of Varying Hemodynamic and Vascular Conditions on Fractional Flow Reserve: An In Vitro Study

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundThe aim of this study was to investigate the impact of varying hemodynamic conditions on fractional flow reserve (ratio of pressure distal [Pd] and proximal [Pa] to stenosis under hyperemia) in an in vitro setting.

Fractional flow reserve vs. angiography in guiding management to optimize outcomes in non-ST-segment elevation myocardial infarction: the British Heart Foundation FAMOUS-NSTEMI randomized trial [PDF]

, 2014
Aim: We assessed the management and outcomes of non-ST segment elevation myocardial infarction (NSTEMI) patients randomly assigned to fractional flow reserve (FFR)-guided management or angiography-guided standard care.

Myocardial perfusion MRI compared to fractional flow reserve: a meta-analysis [PDF]

Journal of Cardiovascular Magnetic Resonance, 2015
Methods This meta-analysis was performed in adherence to the PRISMA statement. Two reviewers systematically searched PubMed, EMBASE and Web of Science, using predefined inclusion and exclusion criteria. Only studies using invasive coronary angiography combined with FFR for assessment of intermediate coronary stenoses were included.

Cognitive function in late‐stage HFpEF patients with tricuspid regurgitation undergoing transcatheter tricuspid valve intervention

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1323-1330, December 1, 2022., 2022
Abstract Objectives This study evaluates the impact of transcatheter tricuspid valve interventions (TTVI) on cognitive function (CF), quality of life (QOL), and exercise capacity in late‐stage heart failure with preserved ejection fraction (HFpEF) and relevant tricuspid regurgitation (TR).

Coronary Microcirculation Downstream Non‐Infarct‐Related Arteries in the Subacute Phase of Myocardial Infarction: Implications for Physiology‐Guided Revascularization

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019
Background Concerns exist about reliability of pressure‐wire‐guided coronary revascularization of non‐infarct‐related arteries (non‐IRA). We investigated whether physiological assessment of non‐IRA during the subacute phase of myocardial infarction might

Three-Dimensional Angiographic Characteristics versus Functional Stenosis Severity in Fractional and Coronary Flow Reserve Discordance: A DEFINE FLOW Sub Study

Diagnostics, 2022
Background: Coronary angiography alone is insufficient to identify lesions associated with myocardial ischemia that may benefit from revascularization.

Fractional flow reserve-guided management in stable coronary disease and acute myocardial infarction: recent developments [PDF]

, 2015
Coronary artery disease (CAD) is a leading global cause of morbidity and mortality, and improvements in the diagnosis and treatment of CAD can reduce the health and economic burden of this condition.

Age‐related changes in the coronary microcirculation influencing the diagnostic performance of invasive pressure‐based indices and long‐term patient prognosis

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1195-1205, December 1, 2022., 2022
Abstract Objectives Investigate age‐related changes in coronary microvascular function, its effect on hyperemic and non‐hyperemic indices of stenosis relevance, and its prognostic implications. Background Evidence assessing the effect of age on fractional flow reserve (FFR), resting mean distal intracoronary pressure/mean aortic pressure (Pd/Pa), and ...

Coronary angiography of the ex‐situ beating donor heart in a portable organ care system

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1252-1260, December 1, 2022., 2022
Abstract Objectives To determine safety and feasibility of ex‐situ coronary angiography. Background To cater for the perpetually growing demand for heart donors, interest in donation following circulatory death (DCD) has been rekindled. Further pursuit of donor pool expansion has led to eligibility extension to “marginal” donors who are at higher risk ...
