CTA Coronary Arteries Referencing of image acquisition to the electrocardiographic recording facilitates high temporal and spatial resolution images of cardiovascular tissues that, when combined with intravenously administered iodinated contrast agents, permits primarily for the evaluation of coronary artery disease (CAD) as an etiology for newly diagnosed HF (coronary CT angiography [CTA]). Additionally, these advances can also be used for imaging during dynamic bolus contrast enhancement for the assessment of first-pass tissue perfusion (eg, myocardium) at rest or during pharmacologically induced stress, or the volumetric visualization of intraluminal/intracavity anatomy (eg, coronary artery, LV chamber) or arterial wall changes in static images (ie, CTA; or, without the use Suspected New-Onset and Known Nonacute Heart Failure of intravenous contrast for coronary calcification, calcium scoring for risk stratification). Delayed imaging helps further the detection of fibrous or fatty tissue replacement in cardiac structures (eg, LV wall) [26,29,30]. Despite marked improvements, prevailing concerns about potential complications are still limitations to the use of this modality. Arteriography Coronary Although a traditional gold standard for diagnosing disease of the coronary arteries or ventricles, conventional catheter-based selective coronary angiography is increasingly focused (eg, 38%) on patient-centric atherosclerotic CAD treatment planning or postrevascularization assessment [31]. It is supported by several complementary technologies allowing further characterization of plaque significance (eg, intravascular ultrasonography [US], fractional flow reserve) [32,33]. While concurrent LV ventriculography is dissuaded for LVEF determinations [34], direct hemodynamic measurements reflecting cardiac function maintain a distinct role in assessing a range of cardiovascular conditions in complicated clinical cases.
