Noninvasive Coronary Angiography Using Computed Tomography

Noninvasive coronary angiography with multislice computed tomography.

CONTEXT Multislice computed tomography (MSCT) has recently evolved as a modality for noninvasive coronary imaging. OBJECTIVE To assess the accuracy and robustness of MSCT vs the criterion standard of invasive coronary angiography for detection of obstructive coronary artery disease. DESIGN, SETTING, AND PATIENTS Prospective, single-center study conducted in a referral center setting in Germ...

New Noninvasive Modalities in Coronary Angiography: Cardiac Computed Tomography Angiography

Coronary artery disease (CAD) is a leading cause of mortality and morbidity in most developed countries [1]. CAD is a common and sometimes disabling disorder, although medication therapy, percutaneous coronary intervention and coronary artery bypass grafting have developed recently. Medical doctors need to prevent from developing acute coronary syndrome. The development of non-invasive cardiac ...

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...
