The aim of this study was to determine the prognostic value of fractional flow reserve (FFR) of non-culprit lesions in STEMI patients. We analyzed data of all Compare-Acute patients (Comparison Between FFR Guided Revascularization Versus Conventional Strategy in Acute STEMI Patients With MVD) after PCI, from lesions assessed with FFR and treated medically. The treating...
Magnetic resonance (MR) and fractional flow reserve (FFR) correlate moderately as regards the assessment of non-culprit lesions in patients admitted with acute myocardial infarction who underwent primary angioplasty. For a similar degree of diagnostic accuracy, we would require a visual, semiquantitative, or fully quantitative comprehensive assessment of lesions. This work, soon to be published in...
The vulnerable features of plaque are independently associated to functional measurements done under hyperemia far better than baseline measurements such as iFR. These findings suggest that not only stenosis severity but also plaque features contribute to functional measurements. This is a sub-study of the PACIFIC (Prospective Comparison of Cardiac PET/CT, SPECT/CT Perfusion Imaging and CT...
Diabetes does not seem to alter the results of a fractional flow reserve (FFR) measurement in a given lesion. Recently, expert opinions and small studies had questioned the reliability of FFR in this specific patient subgroup. This new observational study soon to be published in JAMA vanquishes all doubts and confirms the efficacy of this...
The results of this great multicenter “real-life” registry are similar to those of randomized clinical trials that studied fractional flow reserve (FFR). Lesion deferral based on FFR is a very safe strategy, even for lesions located in the proximal anterior descending artery. Randomized controlled studies FAME and DEFER convincingly showed the safety of lesion revascularization...
In patients undergoing transcatheter aortic valve replacement (TAVR), fractional flow reserve (FFR) guided revascularization is associated with favorable results compared against the traditional angiography guided revascularization. Given the complete lack of randomized studies, this observational study is the best we have to decide how to guide revascularization in patients with symptomatic severe aortic stenosis undergoing...
The aim of revascularization, whether through angioplasty or surgery, is to restore adequate flow to the myocardium; that much is obvious. However, after millions of “successful” procedures with the best technology applied to drug-eluting stents and optimal medical treatment, we still have a high ratio of patients who experience new events. Could an optimal angiographical...
According to the post hoc analysis of the DEFINE-FLAIR, patient sex seems to affect instantaneous wave-free ratio (iFR) and fractional flow reserve (FFR) guided revascularization outcomes. Even though this is not specified in the study protocols, it might affect the gold standard for functional lesion assessment. However, clinical outcomes are similar with both strategies. Therefore,...
In the next days, Dr. Seung Hun and colleagues will publish in J Am Coll Cardiol Intv 2019 a study that answers the title question and also brings peace of mind about the decisions we make based on one of these measurements or the other. This study assessed the physiologic characteristics of discordant lesions between...
Courtesy of SBHCI. This interesting study presented at TCT 2019 and simultaneously published in Am J Cardiol tells us PCI in stable coronary artery disease cannot lower risk in patients with severe aortic stenosis undergoing transcatheter aortic valve replacement (TAVR). Unless patients are symptomatic, most coronary artery lesions do not need revascularization according to researchers....
