Improved Precision of Initial Chest Pain Evaluation With Fractional Flow Reserve Computed Tomography

Improved Precision of Initial Chest Pain Evaluation With Fractional Flow Reserve Computed Tomography

F ollowing publication of the FAME (Fractional Flow Reserve Versus Angiography for Multivessel Evaluation) trial, there has been a noticeable increase in the use of fractional flow reserve (FFR) in the cardiac catheterization laboratories across the country. The FAME study provided evidence in support of FFR-guided revascularization. This was a welcome change as opposed to trusting the gold sta...

Coronary Computed Tomography Angiography With Selective Noninvasive Fractional Flow Reserve

Coronary Computed Tomography Angiography With Selective Noninvasive Fractional Flow Reserve

Based on review of available data, the Company may consider the use of noninvasive fractional flow reserve (FFR) following a positive coronary computed tomography angiography (CCTA) to guide decisions about the use of invasive coronary angiography (ICA) in patients with stable chest pain at intermediate risk of coronary artery disease (CAD i.e., suspected or presumed stable ischemic heart disea...

Coronary Computed Tomography Angiography with Selective Noninvasive Fractional Flow Reserve

Fractional flow reserve using coronary computed tomography angiography requires at least 64slice coronary computed tomography angiography and cannot be calculated when images lack sufficient quality (HeartFlow, 2013) (11% to 13% in recent studies; Koo et al, 2011; Min et al, 2012; Nakazato et al, 2013; Nørgaard et al, 2014), e.g., in obese individuals (e.g., body mass index, >35 kg/m2). The pre...
