Decrease of fractional flow reserve shortly after percutaneous coronary intervention.
BACKGROUND The aim of the present study was to quantitatively assess the physiological acute recoil after percutaneous coronary intervention (PCI), and to determine the relation between it and target lesion revascularization (TLR) in the chronic phase. METHODS AND RESULTS This study evaluated 76 patients who underwent elective PCI between May 1997 and December 2001: plain old balloon angiopla...
متن کاملFractional flow reserve versus angiography for guiding percutaneous coronary intervention.
BACKGROUND In patients with multivessel coronary artery disease who are undergoing percutaneous coronary intervention (PCI), coronary angiography is the standard method for guiding the placement of the stent. It is unclear whether routine measurement of fractional flow reserve (FFR; the ratio of maximal blood flow in a stenotic artery to normal maximal flow), in addition to angiography, improve...
متن کاملFractional flow reserve and complex coronary intervention.
This paper aims to provide a short overview of the theoretical background for coronary pressure-derived fractional flow reserve (FFR) index and to focus on its clinical applicability in complex coronary intervention.
متن کاملFractional flow reserve versus angiography for guiding percutaneous coronary intervention: a meta-analysis
OBJECTIVES The purpose of this study was to investigate whether fractional flow reserve (FFR) should be performed for patients with coronary artery disease (CAD) to guide the percutaneous coronary intervention (PCI) strategy. BACKGROUND PCI is the most effective method to improve the outcomes of CAD. However, the proper usage of PCI has not been achieved in clinical practice. METHODS A meta...
متن کاملPercutaneous Coronary Intervention or No Percutaneous Coronary Intervention: Why Does the Gold Not Always Glitter?
Time and time again, randomized clinical trials have demonstrated that what is conceptually logical and should be right is not always right. Randomized large clinical trials are often undertaken on the basis of this logical hypothesis. Very often, small clinical trials also show encouraging results.1,2 However, when large randomized clinical trials are performed, they not infrequently reveal ra...
