Original title: Atherosclerotic Plaque Characteristics by CT Angiography Identify Coronary Lesions That Cause IschemiaA Direct Comparison to Fractional Flow Reserve. Reference: Hyung-Bok Park et al. J Am CollCardiolImg. 2015;8(1):1-10. This trial evaluated the characteristics of arteriosclerotic plaques and its association with lesion ischemia by CT angiography (CTA) vs fractional flow reserve (FFR). FFR is the gold standard to...
Original title: The impact of age flow reserve-guided percutaneous coronary intervention: A FAME (Fractional Flow Reserve versus Angiography for Multivessel Evaluation) trial substudy. Reference: Hong-Seok Lim et al. International Journal of Cardiology 2014; 177:66-70 The FAME study has shown the benefit of FFR guided PCI, but the question as to whether age affects lesion evaluation remains unclear. A...
Original title: Outcome impact of coronary revascularization strategy reclassification with fractional flow reserve at time of diagnostic angiography. Reference: Van Belle E et al. Circulation. 2014 Jan 14;129(2):173-85. Any comprehensive registry has not been yet published that evaluates the impact of fractional coronary flow reserve (FFR) to change the strategy of revascularization on individual patients referred for diagnostic...
Original title: Long-term clinical outcome after fractional flow reserve– versus angio-guided percutaneous coronary intervention in patients with intermediate stenosis of coronary artery bypass grafts. Reference: Luigi Di Serafino et al. Am Heart J 2013;166:110-8. Bypass coronary angioplasty is often preferred strategy versus re-operation , however it is associated with a greater number of events, both short and long...
Original title: Long-term outcomes of fractional flow reserve-guided vs. angiography-guided percutaneous coronary intervention in contemporary practice. Reference: Li J et al. Eur Heart J. 2013; Epub ahead of print Precision of the fractional flow reserve (FFR) to estimate the functional compromise of coronary stenosis and its ability to reduce events to decide PTCA, based on their outcome has...
Original title: FIRST: Fractional Flow Reserve and Intravascular Ultrasound Relationship Study Reference: Ron Waksman et al. J Am Coll Cardiol 2013. Article in Press For patients with angiographically assessed intermediate lesions such as stenosis between 40% and 80%, criteria that favor revascularization remains under debate. Fractional Flow Reserve (FFR) is considered the gold standard to assess intermediate lesions,...
In patients with ST-segment elevation acute myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (primary PCI), multivessel disease is observed in up to 40% of cases. The optimal timing for revascularizing non-culprit lesions in these patients without cardiogenic shock remains a controversial issue. European guidelines recommend completing revascularization during the initial procedure or within 45 days...
The hyperemic stenosis resistance index (HSR) was introduced as a more complete hemodynamic severity indicator of a coronary lesion. HSR combines both pressure drop across a lesion and the flow through it, therefore overcoming the limitations of traditional indices such as fractional flow reserve (FFR) and coronary flow reserve (CFR). The aim of this multicenter...
The aim of this randomized open study was to determine whether CTO guided left main percutaneous coronary intervention (PCI) is superior to fluoroscopy guided PCI, using fractional flow reserve (FFR) after stenting. The secondary outcomes were procedural success (successful implantation, malposition, edge dissection or stent collapse) and major adverse cardiovascular events (MACE) at one year....
Coronary revascularization aims at improving coronary flow. However, after successful percutaneous coronary intervention (PCI) a significant number of patients might experience suboptimal coronary physiology. It has been observed that low fractional flow reserve (FFR) after PCI is associated to poor prognosis. Also, improved FFR after procedure directly correlates with improved angina symptoms. Pullback pressure during...
