Original title: Revascularization Decisions in Patients With Stable Angina and Intermediate Lesions. Results of the International Survey on Interventional Strategy. Reference: Gabor G. Toth et al. CircCardiovascInterv. 2014. Epubahead of print.   Measurement of fractional flow reserve (FFR) is recommended by the guidelines and supported by evidence in intermediate lesions when not any proof of ischemia is available...

Original title: Fractional Flow Reserve–Guided PCI for Stable Coronary Artery Disease. The FAME 2 Trial Investigators. Reference: Bernard De Bruyne et al. N Engl J Med 2014;371:1208-17. The FAME 2 and the COURAGE studies tested similar hypothesis, only in the first study PCI was guided by fractional flow reserve (FFR) in addition to an angiography. The study hypothesis...

Original title: Intravascular Ultrasound-Derived Minimal Lumen Area Criteria for Functionally Significant Left Main Coronary Artery Stenosis. Reference: Seung-Jung Park et al. J Am Coll Cardiol Intv. 2014;7(8):868-874. Deciding on a course of action when facing intermediate main left stenosis is usually challenging. We tend to overestimate the lesion or to use additional methods, other than angiography, to tip...

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: Percutaneous coronary intervention outcomes in patients with stable obstructive coronary artery disease and myocardial ischemia: A collaborative meta-analysis of contemporary randomized clinical trials. Reference: Stergiopoulos K el al. JAMA Intern Med 2013; DOI:10.1001/jamainternmed.2013 The amount in ischemic patients with stable coronary heart disease is associated with poor prognosis. However, it is unclear whether revascularization to reduce...

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: Thinking Out of the Lumen: FFR Vs. Intravascular Imaging for MACE Prediction. Reference: Pedro R. Moreno et al. J Am Coll Cardiol, article in press. Intravascular imaging studies have shown that the lesions most likely to produce coronary events usually have modest luminal stenosis, large cap burden and thin fibrous cap. These plaques will evolve into a...

Original title: Multislice Computed Tomography Angiography for Non-invasive Assessment of the 18-Months Performance of a Novel Radiolucent Bioresorbable Vascular Scaffolding Device (ABSORB Trial). Reference: Koen Nieman et al. J Am Coll Cardiol, article in press. Metal stents revolutionized coronary angioplasty procedures; however, they are permanent prosthetic devices that make re intervention difficult and prolongue thrombosis risk. This problem...
