CTA based FFR, a software based application, enhances diagnostic value of coronary computed tomography angiography (CTA) examination. However it remains unknown whether it improves accuracy over the gold standard of invasive coronary angiography (ICA) in predicting functionally significant coronary stenosis...
2.1 介入术前无创功能学评估:CT-FFR 对于疑诊冠心病患者,CTA是最常用的诊断手段,其敏感性高,但因特异性不足,常导致不必要的冠脉造影。过去10年,多种CT-FFR技术如雨后春笋般出现,通过计算流体力学或人工智能与冠脉生理学参数相结合,计算出一个心动周期内冠脉树任一点的CT-FFR值,明确CTA冠脉狭窄的功能学意义[12...
“The critical role of CTA in the diagnosis and management of coronary artery disease continues to drive every decision we make, ensuring the right patients are getting the right care at the right time,” said Campbell Rogers,...
July 17, 2024 — HeartFlow, a leader in non-invasive artificial intelligence (AI) heart care solutions, today announced it will be presenting new findings on the use of coronary computed tomography angiography (coronary CTA) in coronary artery disease (CAD) management and insights...
Coronary CTA stenosis, plaque volumes, FFRCT, and FFR were assessed in 484 vessels from 254 patients. Stenosis >50% was considered obstructive. Plaque volumes (non-calcified plaque [NCP], low-density NCP [LD-NCP], and calcified plaque [CP]) were quantified using semi-automated software. ...
Only 50% of obstructed vessels with ≥ 50% luminal narrowing by CTA show abnormal MPI[48]. We previously indicated that 64-slice CTA alone was not always sufficient to assess the functional significance of anatomic stenoses, especially stenoses of intermediate grade (Figure 4). When stenosis ...

Fractional flow reserve (FFR) has been established as gold standard to detect hemodynamically significant coronary artery disease. Non-invasive FFR derived from coronary computed tomography angiography (CTA; FFRCT) has demonstrated higher diagnostic performance compared with FFR. However, the accuracy and ...
