Of that, approximately 7.4 million deaths result annually from coronary artery disease (CAD) alone (1). Coronary CT angiography (CTA) has been shown, in both clinical studies and real- world usage, to provide clinicians with valuable information about patients at risk for CAD. Coronary CTA as frontline assessment While other non-invasive tests may overlook patients with heart disease, the detailed information available from coronary CTA draws attention to those who may otherwise be missed (2,3). Recently updated guidelines recommend coronary CTA as a frontline assessment in symptomatic stable patients with low to intermediate pre-test probability of obstructive CAD (4,5). CAD diagnosis and management requires understanding of two fundamental questions While coronary CTA allows clinicians to identify and quantify the severity of coronary artery disease, determining the impact that any specific stenosis has on downstream ischemia is still a challenge, meaning that many patients may have disease that will not benefit from invasive intervention. This reality drives the low diagnostic yield of invasive coronary angiography (ICA) seen globally today. In many cases, further testing before referral to ICA is needed (6). Helping to identify ischemia-causing lesions Today, CT-derived Fractional Flow Reserve (FFRCT) is the only non-invasive test that provides actionable information to aid clinicians in determining, vessel-by-vessel, the functional significance of coronary artery lesions. In three prospective multicenter trials, the HeartFlow® FFRCT Analysis has shown higher specificity and positive predictive value (PPV) compared to coronary CTA alone (7-9). Now, Siemens Healthineers and HeartFlow are working together to provide clinicians with improved access to the benefits of coronary CTA and HeartFlow FFRCT within an optimized workflow. 3 Siemens Healthineers and HeartFlow collaboration When excellent image quality is key Every HeartFlow FFRCT Analysis begins with a standard coronary CTA. After the acquisition of high quality images, HeartFlow is able to extract a personalized anatomical model from the coronary CTA data and perform a detailed segmentation of the coronary arteries for each patient. Delivering the technical solutions needed Acquiring these high quality images requires sharp, motion-free visualization of the coronary arteries. To make this possible, Siemens Healthineers provides solutions that are designed to maximize both temporal Courtesy of University Hospital Erlangen, Germany and spatial resolution.

The Stellar Detector reduces blooming and enhances vessel delineation with a very high spatial resolution. Additionally, Siemens Healthineers offers dedicated edge-enhancing kernels for coronary imaging and image sharpening for a thorough evaluation of calcified lesions. 4 Siemens Healthineers and HeartFlow collaboration Initial clinical experience The work performed at Aarhus University Hospital, a facility equipped with Siemens Healthineers’ unique Dual Source technology, demonstrates the impact that this continuous introduction of powerful product innovations provides to both patients and clinicians. Adapting their standard clinical workflow – Frontline cCTA combined with selective FFRCT In assessing their standard clinical practice, Dr. Jensen and his colleagues changed their diagnostic workflow to include frontline coronary CTA with selective use of the HeartFlow FFRCT Analysis testing in all symptomatic patients with suspected stable CAD (10). Coronary CTA was acquired in 774 patients with high diagnostic image quality found in 97% of scans. Out of the 212 patients submitted for downstream testing with FFRCT, 99% of the low/intermediate risk group and 97% of the high-risk group were accepted for the HeartFlow FFRCT Analysis. Excellent diagnostic image quality 97%–99% Furthermore, an earlier evaluation of the work at Aarhus University Hospital showed similar findings: of 1,248 of images accepted for HeartFlow FFRCT patients referred for coronary CTA performed using a Siemens Dual Source scanner, 97% were of excellent diagnostic image quality (11). Here, 189 patients were referred for FFRCT, with a HeartFlow FFRCT Analysis obtained in 185 (98%). These results are exemplary, and highlight the value of high-quality coronary CTA, especially when taking into This shows that through the combination of latest- account the more challenging clinical realities of Aarhus’ generation scanner equipment, acquisition protocols high-risk patient group, including patients with higher and trained staff, Jensen et al. were able to achieve mean Agatston scores. a very high acceptance rate . 5 Siemens Healthineers and HeartFlow collaboration Delivering the data clinicians need Together, coronary CTA and the HeartFlow FFRCT Analysis enable clinicians to identify significant coronary artery disease and determine the optimal treatment pathway. Greatly reduce unnecessary invasive testing The PLATFORM Study, a prospective comparative While ICAs were reduced, coronary revascularizations effectiveness trial enrolling 584 patients at 11 medical were maintained (13), meaning that the patients needing centers, compared a coronary CTA and HeartFlow coronary interventions were still treated. FFRCT guided pathway to usual care for patients with suspected CAD. Clinical sites across the world have demonstrated that the real-world adoption of a coronary CTA and HeartFlow When utilizing a coronary CTA and HeartFlow FFRCT FFRCT guided pathway has led to similar reductions in ICAs guided pathway, physicians were able to safely cancel while maintaining revascularizations. 61% of scheduled invasive coronary angiograms (ICAs) (12) with zero adverse clinical events occurring through one year among patients whose ICA was canceled. (13) $ Improved patient experience Reduce costs to the healthcare system Patients reported a significant improvement in quality of The coronary CTA and HeartFlow FFRCT guided pathway life and experienced a reduction in unnecessary invasive has been shown to reduce overall costs to the healthcare procedures due to a coronary CTA and HeartFlow FFRCT system by 26% compared with usual care testing for guided pathway.
