Fractional Flow Reserve in PCI

By  |  January 15, 2009 | 

Usually the decision to stent a coronary vessel is primarily determined by the % stenosis of the vessel. In this RCT of >1000 patients, they were randomized to stenting according to angiography alone, or to angiography in addition to the Fractional Flow Reserve (FFR; ratio of maximal blood flow in a stenotic vessel versus normal maximal blood flow). In the FFR group, the vessel was stented only if the FFR was <0.8. The numbers of stents per patient in the standard group was 2.7, versus 1.8 in the FFR group. The primary endpoint (1-year death, MI, or re-vascularization) occured in 18% of the standard group and only 13% of the FFR group. We should be aware that using FFR in addition to standard angiography will likely be used to guide stenting decisions in the cath lab. (abstract)

The Centers for Medicare & Medicaid Services (CMS) has not updated its rules (“conditions for participation”) for nursing homes in twenty-five years. Late last year they finally did.
