Insights
Multislice computed tomography (MSCT) reveals significant anatomical variability in the coronary venous system (CVS). This imaging technique is valuable for visualizing CVS variants before cardiac resynchronization therapy (CRT) implantation.
Area of Science:
- Cardiovascular Imaging
- Anatomical Pathology
- Medical Technology
Background:
- The coronary venous system (CVS) exhibits considerable anatomical variability, though its variants are not fully analyzed.
- Understanding CVS anatomy is crucial for interventional cardiovascular procedures.
Purpose of the Study:
- To evaluate the anatomical variants of the coronary venous system (CVS) using multislice computed tomography (MSCT).
- To assess the feasibility of visualizing target veins for cardiac resynchronization therapy (CRT) via MSCT.
Main Methods:
- 199 patients underwent 64-slice computed tomography with electrocardiogram-gating and 0.5mm slice thickness.
- 3D volume rendering and 2D multi-planar reformatted reconstructions of the CVS were generated.
- Specific target veins for CRT (posterolateral, lateral, anterolateral) were identified.
Main Results:
- The coronary sinus was visualized in all patients.
- A total of 27 CVS anatomical variants were identified, with 9 common variants occurring in 74.4% of cases.
- The number of target veins for CRT varied, with at least one vein present in most patients; however, 3.0% had no veins in the target area.
Conclusions:
- The majority of patients had at least one target vein for CRT visualized.
- MSCT is effective in demonstrating CVS anatomical variability, supporting its role in pre-CRT planning.
Background:
In a few studies, huge anatomical variability of coronary venous system (CVS) has been documented without analysis of its variants. The aim of the present study was to evaluate anatomical variants of CVS in multislice computed tomography (MSCT).
Methods And Results:
In 199 patients (114 males, age 56.6±11.5 years), a 64-slice computed tomography (Aquilion 64) was performed due to coronary artery disease suspicion. A scan with electrocardiogram-gating was performed using a slice thickness of 0.5mm during a breath-hold. In each case, 3D volume rendering and 2D multi-planar reformatting reconstructions of CVS were created (Vitrea 2). As target veins for cardiac resynchronization therapy (CRT), the posterolateral, lateral and anterolateral veins were recognized. Coronary sinus was well visualized in all cases. A total of 27 anatomical variants of CVS were identified, 9 of them are most common (in 148/199 cases; 74.4%). In 4 out of these 9 variants, a single coronary vein in the target area for CRT appeared, 2 target veins in 3 variants and 3 veins in 2 variants occurred. In 6 cases (2 seldom variants-3.0%) no veins in the target area were identified.
Conclusions:
In the majority of the examined patients, at least one vein in the target area for CRT was observed. Anatomical variability of CVS strengthen the potential role of MSCT in CVS visualization before CRT implantation.

Coronary Circulation
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...
Overview of Systemic Veins
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the middle...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
