It is therefore of utmost importance that interventional cardiologists become familiar with image interpretation and up-to-date regarding several CCTA features, taking advantage of this information in planning the procedure, ultimately leading to improvement in patient outcomes.Abstract:
In recent years, coronary CT angiography (CCTA) has become a widely adopted technique, not only due to its high diagnostic accuracy, but also to the fact that CCTA provides a comprehensive evaluation of the total (obstructive and non-obstructive) coronary atherosclerotic burden. More recently, this technique has become mature, with a large body of evidence addressing its prognostic validation. In addition, CT angiography has moved from the field of ‘imagers’ and clinicians and entered the interventional cardiology arena, aiding in the planning of both coronary and structural heart interventions, being transcatheter aortic valve implantation one of its most successful examples. It is therefore of utmost importance that interventional cardiologists become familiar with image interpretation and up-to-date regarding several CTA features, taking advantage of this information in planning the procedure, ultimately leading to improvement in patient outcomes. On the other hand, the increasing use of CCTA as a gatekeeper for invasive coronary angiography is expected to lead to an increase in the ratio of interventional to diagnostic procedures and significant changes in the daily cath-lab routine. In a foreseeable future, cath-labs will probably offer an invasive procedure only to patients expected to undergo an intervention, perhaps becoming in this change true interventional-labs.read more

Hooman Bakhshi,Zahra Meyghani,Satoru Kishi,Tiago A. Magalhães,Andrea Vavere,Pieter H. Kitslaar,Richard T. George,Hiroyuki Niinuma,Johan H. C. Reiber,Aisha Betoko,Matthew B. Matheson,Carlos E. Rochitte,Marcelo F. Di Carli,Christopher Cox,Joao A.C. Lima,Armin Arbab-Zadeh +15 more
TL;DR: Various plaque metrics obtained by cardiac CT predict provocable myocardial ischemia by CT perfusion imaging through their association with maximum percent stenosis, while none had significant incremental value.

Cardiac Computed Tomography for Comprehensive Coronary Assessment: Beyond Diagnosis of Anatomic Stenosis
TL;DR: The ability of CCTA to provide comprehensive assessment of a patient with suspected CAD is discussed, including functional techniques of stress-rest myocardial perfusion assessment using a vasodilator and a purely post-processing approach that assesses fractional flow reserve derived by CCTa.

TL;DR: The SYNTAX score (SXscore) is an important tool to grade angiographic complexity and to risk-stratify patients being considered for revascularization; moreover, it has been reported as an independent predictor of major adverse cardiac events in all-comers–type populations with a varying number of patients.

Discordance between Framingham Risk Score and atherosclerotic plaque burden
TL;DR: Although clinical variables are predictive of CAD events, CTA identified coronary atherosclerosis in a significant proportion of patients with low to intermediate FRS, and a small minority of patients without a history of diabetes mellitus, myocardial infarction, and not on statin therapy had no evidence of Atherosclerotic plaque.
