A protocol update of the Fractional Flow Reserve versus Angiography for Multivessel Evaluation FAME 3 trial. The index FFR Fractional Flow Reserve is based upon the two following principles.

Physiological Assessment Of Coronary Artery Disease Ffr Ifr Ppt Download

Fractional flow reserve FFR is an invasive measurement developed in 1990s for evaluation of functional significance of stenoses in the epicardial coronary artery.

. Fractional flow reserve versus angiography for guiding percutaneous coronary intervention. As opposed to anatomical approaches physiological measurements particularly pressure-derived FFR assess the function of the coronary circulation and offer the possibility of ad hoc treatment. In patients with complex three-vessel coronary artery disease CAD PCI guided by measurement of fractional flow reserve FFR with a current generation drug-eluting stent did not meet the criterion for noninferiority compared with CABG in terms of death myocardial infarction MI stroke or revascularization at one year according to findings from FAME 3 trial.

Fractional Flow Reserve No Gradient Minimal Moderate Severe. Fractional flow reserve FFR is a procedure that is based on guide-wire which can appropriately measure the blood pressure and flow via specific part of the coronary artery. Background Fractional flow reserve FFR defined as the ratio of maximum flow in the presence of a stenosis to normal maximum flow is a lesion-specific index of stenosis severity that can be calculated by simultaneous measurement of mean arterial distal coronary and central venous pressure P a P d and P v respectively during pharmacological vasodilation.

The instantaneous flow reserve iFr was the first of these indexes and two large studies have shown that this parameter is non-inferior to FFR in terms of patient prognosis5. FFR is defined as a ratio of the maximal myocardial blood flow in the presence of a stenosis to the theoretical normal maximal flow in the same distribution. In 196 patients undergoing pretranscatheter aortic valve replacement CT fractional flow reserve CT-FFR assessment those with CT-FFR 075.

Fractional Flow Reserve Tonino et al. This can easily be measured by the process using a pressure wire. Fractional Flow Reserve Based on the principle that the distal coronary pressure measured during vasodilation is directly proportional to maximum vasodilated perfusion.

Fractional Flow Reserve Distal Pressure Pd Proximal Pressure Pa FFR P d Pa during maximal flow Pd Pa Pd Pa 60 100 FFR 060. Fractional flow reserve FFR and instantaneous wave-free ratio are the present standard diagnostic methods for invasive assessment of the functional significance of epicardial coronary stenosis. 3 SS is an anatomic scoring system based on coronary angiogram.

Should it be routine or individualized according to very specific need in MVD. Fractional flow reserve FFR is a reliable index of functional severity for epicardial vessel stenosis. Fractional flow reserve FFR is emerging as a useful clinical tool for assessing the functional significance of coronary atherosclerosis.

Fractional flow reserve FFR is a procedure used in coronary catheterization to calculate variations in pressure across coronary artery stenosis. Despite the overall trend towards more physiology-guided revascularization there remains a gap between. Fractional flow reserve FFR is an index of the physiological significance of a coronary stenosis and is defined as the ratio of maximal blood flow in a.

The measurement of Fractional Flow Reserve has been shown useful in assessing whether or. A standard diagnostic catheter at the time of a coronary angiogram which is also known as cardiac catheterization is used to perform the fractional flow reserve procedure. Fractional Flow Reserve Hyperemia the increase in blood perfusion to different tissues in the body through dilation of the microvasculature.

This determines whether the flow of your blood is healthy or not. The original description of FFR required the induction of maximal hyperemia to achieve near linear correlation between coronary pressure and blood flow. This process helps to determine the likelihood of stenosis which impedes the supply of.

Fractional flow reserve measurement Induce proper maximal hyperaemia Interpret the tracing appropriately Obtain accurate measurements ETP course 2014 Sophia-Antipolis FFR. Coronary CT Fractional Flow Reserve before Transcatheter. 1 Fractional Flow Reserve guided Intervention.

Fractional flow reserve FFR is defined as the ratio of maximum blood flow in a stenotic coronary artery to maximum blood flow if the same artery were completely normal. Fractional Flow Reserve or FFR is a guide wire-based procedure that can accurately measure blood pressure and flow through a specific part of the coronary artery. ETP course 2014 Sophia-Antipolis FFR.

FFR is done through a standard diagnostic catheter at the time of a coronary angiogram aka. Tonino PA De Bruyne B Pijls NH et al. An FFR of 080 or less as measured with the use of a coronary pressure wire during invasive coronary angiography indicates the potential of a specific stenosis to induce.

Fractional flow reserve in clinical practice. Fractional flow reserve is the simple ratio of the maximum achievable flow of the diseased coronary artery to the flow of blood in the normal artery. It is not resting flow but maximum achievable flow which determines the functional capacity exercise tolerance of a patient At maximum vasodilation corresponding with maximum hyperemia or with maximum exercise.

A comparison of fractional flow reserve-guided percutaneous coronary intervention and. New England Journal of Medicine 2009. N Engl J Med.

Fractional flow reserve measurement based on computed tomography FFRCT is a novel well validated non-invasive method for determining the presence and extent of coronary artery disease CAD combined with a physiological assessment of vessel-specific ischemia in patients with chest pain. Thank you for your attention. It 1 - Qualifies.

Amr Zaki Alexandria University The answer is. 1 The most commonly used pharmacological agent is adenosine as an intravenous infusion. Davies JE et al Use of the Instantaneous Wave-free Ratio or Fractional Flow Reserve in PCI.

FFR immediately after stenting to assess the impact of the treatment on coronary flow and the possible residual stenosis has been poorly investigated and data on this specific FFR application are sparse. A healthy and a normal flow of the blood is considered as 10. More recently a number of other parameters have been developed among which the RFR resting flow ratio which can be measured with the same intracoronary wire as the.

Fractional flow reserve FFR utilizes a specialized guide wire to measure blood pressure within a coronary artery. N Engl J Med. FFR is defined as the ratio of maximum blood flow in a stenotic artery to maximum blood flow in the same artery if there were no stenosis.
