Comparison of Outcomes between Fractional-Flow-Reserveand Angiography-Directed Intervention in Non-ST Elevation Acute Coronary Syndrome.

J Coll Physicians Surg Pak 2019 Mar;29(3):268-273

Department of Cardiology, Heart Center, Chongqing Three Gorges Central Hospital, Wanzhou, Chongqing, 404000, China.

Among the sick patients suffering from non-ST segment elevation acute coronary syndrome (NSTEACS), the accuracy of fractional flow reserve (FFR)-directed percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) is still ambiguous. Studies were obtained from PubMed, Embase, Wanfang Data, and Cochrane Library electronic statistics from their initiation up to April 2018, to explore the differences between the FFR-directed approach and the coronary angiography (CA)/stress perfusion scintigraphy (SPS)-directed approach in the outcomes of NSTACS patients. Odds ratio was determined for individual studies, quality assessments, heterogeneity, and publishing bias analyses. Read More

FFR for Complex Coronary Artery Disease Treatment Planning: New Opportunities.

Interv Cardiol 2018 Sep;13(3):126-128

St Paul's Hospital & University of British Columbia, Vancouver, British Columbia Vancouver, Canada.

Coronary computed tomography (CT) is well established for the assessment of symptomatic patients with suspected but not yet confirmed coronary artery disease with high diagnostic accuracy and risk prediction. Until recently, coronary computed tomography angiography (CTA) has played a limited role in the management of complex coronary artery disease (CAD) and in planning revascularisation strategies. With the advent of FFR, enabling anatomy and physiology with a single study and the ability to adjudicate lesion specific pressure loss, the potential of combined coronary CT angiography (CCTA) and fractional flow reserve (FFR) computed from non-invasive CT angiography (FFR) to inform treatment decision-making and help guide revascularisation has been recognised.

Fractional Flow Reserve or Coronary Flow Reserve for the Assessment of Myocardial Perfusion : Implications of FFR as an Imperfect Reference Standard for Myocardial Ischemia.

Curr Cardiol Rep 2018 Jul 26;20(9):77. Epub 2018 Jul 26.

Amsterdam UMC, University of Amsterdam, Department of Cardiology, Heart Centre, Meibergdreef 9, Amsterdam, The Netherlands.

Purpose Of Review: Accumulating evidence exists for the value of coronary physiology for clinical decision-making in ischemic heart disease (IHD). The most frequently used pressure-derived index to assess stenosis severity, the fractional flow reserve (FFR), has long been considered the gold standard for this purpose, despite the fact that the FFR assesses solely epicardial stenosis severity and aims to estimate coronary flow impairment in the coronary circulation. The coronary flow reserve (CFR) directly assesses coronary blood flow in the coronary circulation, including both the epicardial coronary artery and the coronary microvasculature, but is nowadays less established than FFR.

Appropriate use of noninvasive ischemia testing to guide revascularization decision making following acute ST elevation myocardial infarction in Latin American countries: Results from an expert panel meeting of the International Atomic Energy Agency.

Rev Esp Med Nucl Imagen Mol 2018 Jul - Aug;37(4):237-243. Epub 2018 May 31.

International Atomic Energy Agency, Viena, Austria.

Across Latin American and Caribbean countries, cardiovascular disease and especially ischemic heart disease is currently the main cause of death both in men and in women. For most Latin American and Caribbean countries, public and community health efforts aim to define care strategies which are both clinically and cost effective and promote primary and secondary prevention, resulting in improved patient outcomes. The optimal approach to deal with acute events such as ST-elevation myocardial infarction (STEMI) is a matter of controversy; however, there is an expanding role for assessing residual ischemic burden in STEMI patients following primary percutaneous coronary intervention.

Impact of cardiac hybrid imaging-guided patient management on clinical long-term outcome.

Int J Cardiol 2018 06;261:218-222

Department of Nuclear Medicine, Cardiac Imaging, University Hospital Zurich, Ramistrasse 100, 8091 Zurich, Switzerland.

Background: Although randomized trials have provided evidence for invasive fractional flow reserve to guide revascularization, evidence for non-invasive imaging is less well established. The present study investigated whether hybrid coronary computed tomography (CCTA)/single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) can identify patients who benefit from early revascularization compared to medical therapy.

Methods: This retrospective study consists of 414 patients referred for evaluation of known or suspected coronary artery disease (CAD) with CCTA/SPECT hybrid imaging. Read More

Physiology-Guided Management of Serial Coronary Artery Disease: A Review.

JAMA Cardiol 2018 May;3(5):432-438

Cardiovascular Division, St Thomas' Hospital Campus, King's College London, England.

Importance: Ischemia-guided revascularization is the cornerstone of contemporary management of coronary artery disease and has evolved from noninvasive functional evaluation to real-time assessment with invasive physiological indices during diagnostic catheterization. However, serial/diffuse disease is common, and revascularization decisions often need to be made about individual lesions within the same vessel. It is unclear whether current physiological techniques, such as fractional flow reserve, can be reliably used to discern the individual contribution of lesions within a serially diseased vessel with erroneous measurements, potentially leading to suboptimal revascularization decisions.

JACC Cardiovasc Interv 2018 02;11(4):354-365

Department of Cardiovascular Sciences, Policlinico Umberto I Roma, Rome, Italy. Electronic address:

Objectives: This study sought to prospectively assess the impact of routine invasive physiology at the time of angiography on reclassification of therapeutic management of multivessel disease (MVD) patients, and to assess how implementation of instantaneous wave-free ratio (iFR) alters the process.

Background: Routine invasive physiology in intermediate coronary lesions at the time of diagnostic angiography, primarily in patients with single-vessel disease and using fractional flow reserve (FFR), reclassifies coronary revascularization management in 26% to 44% of patients. The role of invasive physiology in patients with MVD is unclear. Read More

Design and Rationale of the RIPCORD 2 Trial (Does Routine Pressure Wire Assessment Influence Management Strategy at Coronary Angiography for Diagnosis of Chest Pain?): A Randomized Controlled Trial to Compare Routine Pressure Wire Assessment With Conventional Angiography in the Management of Patients With Coronary Artery Disease.

Circ Cardiovasc Qual Outcomes 2018 Feb;11(2):e004191

From the Institute of Cardiovascular Medicine and Science, London, United Kingdom (M.E., R.S., I.K.); Liverpool Heart and Chest Hospital NHS Foundation Trust, United Kingdom (M.E., R.S., I.K.); Wessex Cardiothoracic Centre, University Hospital Southampton NHS Foundation Trust, United Kingdom (Z.N., N.C.); and Faculty of Medicine, University of Southampton, United Kingdom (N.C.).

Background: Investigation of anginal chest pain has traditionally involved either assessment of the coronary anatomy by angiography or noninvasive testing for reversible ischemia. Invasive pressure wire assessment at the time of angiography offers information on both anatomy and physiology. Fractional flow reserve-guided percutaneous coronary intervention is associated with lower resource utilization and improved clinical outcome compared with angiographic guidance alone. Read More

Is heart rate response a reliable marker of adenosine-induced coronary hyperemia?

Int J Cardiovasc Imaging 2018 Jul 14;34(7):1117-1125. Epub 2018 Feb 14.

NIHR Biomedical Research Centre and British Heart Foundation Centre of Excellence, School of Cardiovascular Medicine and Sciences, St Thomas' Campus, King's College London, London, UK.

Introduction Growing evidence supports ischemia-guided management of chest pain, with invasive and non-invasive tests reliant upon achieving adenosine-induced coronary hyperemia (defined as increased blood flow to an organ's perfusion bed). In the non-invasive setting, surrogate markers of hyperemia, such as increases in heart rate, are often used, despite not being formally validated. We tested whether heart rate and other non-invasive indices are reliable markers of coronary hyperemia. Read More

Hybrid Imaging in Ischemic Heart Disease.

Rev Esp Cardiol (Engl Ed) 2018 May 10;71(5):382-390. Epub 2018 Jan 10.

Department of Nuclear Medicine, Cardiac Imaging, University Hospital Zurich, Zurich, Switzerland. Electronic address:

Hybrid imaging for ischemic heart disease refers to the fusion of information from a single or usually from multiple cardiovascular imaging modalities enabling synergistic assessment of the presence, the extent, and the severity of coronary atherosclerotic disease along with the hemodynamic significance of lesions and/or with evaluation of the myocardial function. A combination of coronary computed tomography angiography with myocardial perfusion imaging, such as single-photon emission computed tomography and positron emission tomography, has been adopted in several centers and implemented in international coronary artery disease management guidelines. Interest has increased in novel hybrid methods including coronary computed tomography angiography-derived fractional flow reserve and computed tomography perfusion and these techniques hold promise for the imminent diagnostic and management approaches of patients with coronary artery disease.

Fractional flow reserve computed tomography in the evaluation of coronary artery disease.

Cardiovasc Diagn Ther 2017 Oct;7(5):463-474

St Paul's Hospital, Vancouver, Canada.

Amongst patients with suspected obstructive coronary artery disease (CAD), less than a third of patients have obstructive disease on invasive coronary angiography (ICA) and fewer still have flow-limiting obstructive disease as determined by invasive fractional flow reserve (FFR). FFR is a powerful tool in guiding revascularization of flow-limiting lesions which in turn improves clinical outcome in those with haemodynamically significant obstructive disease. However FFR is infrequently performed due to the cost, time and patient discomfort the procedure entails. Read More
