“…Most papers have had a huge influence on the creation of clinical guidelines-in the 2010 version of the appropriate use criteria for cardiac CT, noninvasive coronary vein mapping prior to the placement of a biventricular pacemaker received an A (8), which means that it is highly recommended [63] . When the imaging technology was evaluated and the images started to have an acceptable quality and became more common, creating clinicalpractical guidelines was only a matter of time.…”

“…In this method, an additional left ventricle (LV) lead is placed in the target coronary vein on the surface of the left ventricle. Proper implantation provides the possibility of pacing the left ventricle together with the classic pacing of the right ventricle and usually the right atrium The most important challenge of left ventricle lead implantation is the precise placement in the area where the electrical parameters are assumed to be optimal [8][9][10] . The lead is implanted via the right atrium by the cannulation of the coronary sinus (CS) ostium to the coronary sinus and the great cardiac vein to the lateral or posterolateral veins (typically), which are called the target veins [11,12] .…”

The role of the coronary venous system was underestimated for many years. In the last 20 years, a few percutaneous cardiology techniques in which the anatomy of the coronary venous system was significant were developed and are in use. The most important seems to be cardiac resynchronization therapy, which is an invasive method for the treatment of heart failure. Unfortunately, one of the major problems is the significant anatomical variability of the coronary venous system. The description of the selected anatomical structures is only useful in selected cases such as, for example, the obstruction of selected vessels, a huge Thebesian valve, etc. The 3D images can add significant value; however, their usefulness is limited due to the different points of view that are obtained during intra-operational fluoroscopy. After summarizing all of the articles and guidelines, it can be recommended that the visualization of the coronary venous system be performed in certain patients before cardiac resynchronization. The best option is to use tomography with retrospective gating with the optimal reconstruction of cardiac veins that occurs during the diastolic phases.

“…Cardiac CT allows 3-dimensional acquisition of cardiac function without the limitation of the need for adequate acoustic windows with echocardiography, and hence potentially improves reproducibility for assessment of mechanical dyssynchrony. CT-based dyssynchrony index using time to maximal wall thickness [63] and time to minimum LV volume [64] was highly reproducible was compared to echocardiographic assessment of dyssynchrony. While promising as a single imaging modality for CRT with visualization of the coronary veins, dyssynchrony assessment, and myocardial scar [65], prospective studies are needed to validate the utility of CT derived dyssynchrony index with clinical CRT response.…”

Preprocedural Imaging for Patients with Atrial Fibrillation and Heart Failure

Various electrophysiological procedures and device implantation has been shown to improve morbidity and mortality in patients with atrial fibrillation (AF) and patients with heart failure (HF). Non-invasive cardiac imaging is used extensively in the pre-procedural patient selection and for procedural guidance. In this review, we will discuss the application of pre-procedural cardiac imaging in patients with AF prior to pulmonary vein and left atrial ablation as well as insertion of left atrial occluder device. We also discuss the role of non-invasive cardiac imaging in the selection of appropriate HF patients for device therapy as well as their use in guiding implantation of biventricular pacemaker for cardiac resynchronization therapy by assessing left ventricular ejection fraction, coronary venous anatomy, mechanical dyssynchrony and myocardial scar. We describe new research associated with pre-procedural imaging in these patient cohorts.

“…Echocardiography is the conventional method for the evaluation of LV mechanical dyssynchrony. However, CTA is also able to provide an assessment of mechanical dyssynchrony and was shown to be accurate in a comparison with echocardiography (41). CTA has been proven to be helpful in guiding CRT therapy on this basis (42).…”

Cardiac CT angiography has become an important tool for the diagnosis and treatment of congestive heart failure. Differentiation of ischemic from nonischemic cardiomyopathy; evaluation of myocardial perfusion; characterization of hypertrophic cardiomyopathy, left ventricular noncompaction, and arrhythmogenic right ventricular dysplasia; and delineation of congenital heart defects and valvular abnormalities are the primary diagnostic applications. Therapeutic use includes visualization of the coronary venous anatomy for optimal implementation of cardiac resynchronization therapy and evaluation of left ventricular assist devices and transplant vasculopathy.
