Fractional Flow Reserve
FFR is the reference standard for the physiological assessment of coronary artery stenoses, particularly intermediate ones. FFR is defined as the ratio between mean distal coronary pressure and mean aortic pressure, both measured simultaneously at maximal hyperaemia.5 Coronary pressure is measured using a 0.014-inch sensor-tipped PressureWire™ FFR measurement system (St…

The invasive measurement of fractional flow reserve (FFR) can determine the haemodynamic relevance of coronary artery stenoses. Determination of FFR is recommended in coronary artery stenoses with a luminal diameter narrowing between 50 % and 90 % if no non-invasive proof of ischaemia is available.1 To measure the FFR of a given coronary lesion, a wire or a microcatheter equipped with a…

By using fractional flow reserve (FFR) in patients with multivessel disease, the interventional cardiologist is able to accurately distinguish between coronary stenoses that induce myocardial ischaemia and stenoses that do not induce myocardial ischaemia. Consequently, it is possible to treat selectively the functionally significant stenoses (those responsible for reversible ischaemia, also…

The use of physiology to guide revascularisation in patients with coronary disease has been demonstrated to improve clinical outcomes and reduce costs.1,2 Despite this, its adoption into clinical practice is very low,3 moreover, when it is employed it is used simplistically – only to determine if the vessel is ischaemic or not.
Recently, several new indices of stenosis severity have been…

Coronary artery disease (CAD), the most common cause of morbidity and mortality in the US, is frequently identified by coronary angiography. Decisions for treatment are often based on angiography alone, absent other clinical indicators for intervention. However, by angiography alone, conventional wisdom has suggested that a coronary stenosis is significant if there is at least a 50 % diameter…

Coronary artery disease (CAD) due to atherosclerosis is a major cause of morbidity and mortality. Early prevention of atherothrombotic disease with a healthy lifestyle (diet, exercise, optimal body weight and no smoking) is considered the best method of “treating” CAD, although increasing age remains associated with significant cardiovascular events.
When coronary atherothrombotic disease…

The emphasis in ischaemic heart disease (IHD) diagnosis has historically been directed towards the identification of epicardial coronary stenosis by selective coronary angiography, and its management by percutaneous coronary intervention (PCI) or coronary bypass graft surgery. Over the past two decades, the application of coronary physiology techniques to identify the haemodynamic severity of…

Society for Cardiovascular Angiography and Interventions
The Society for Cardiovascular Angiography and Interventions (SCAI) has just released a focused update to its 2014 consensus statement on the use of invasive assessments of coronary physiology and structure, including the introduction of iFR.
SCAI’s updated consensus statement was published this month in Catherization and Cardiovascular Interventions. Based on the data from the DEFINE-FLAIR and…
