Cavoatrial junction - Wikipedia
The cavoatrial junction (CAJ) is the point at which the superior vena cava meets and melds into the superior wall of the cardiac right atrium. Both the superior and inferior vena cavae enter the right atrium, but only the superior entry is called the cavoatrial junction.

Catheters used for haemodialysis may be placed at the cavo-atrial junction or even in the RA itself. Positioning the catheter tip too proximally, for example in the right or left brachiocephalic veins, is associated with increased risk of line infection and thrombosis.

The most reliable estimate of cavoatrial junction position is a point two vertebral body units below the carina; there was no association with patient age or other parameters. Conclusions: A more accurate understanding of the superior vena cava anatomy is essential for the correct interpretation of central venous access device position.
Radiologist variability in assessing the position of the cavoatrial ...
Interobserver variability of cavoatrial junction (CAJ) identification on chest X-rays for both consultant radiologists and trainees. Interobserver variability refers to the differences in CAJ position between multiple observers. These differences are plotted against the mean of the two CAJ positions relative to the horizontal reference line.
Cavoatrial Junction and Central Venous Anatomy: Implications for ...
The cavoatrial junction appears to be the preferred anatomic landmark to describe the location of central venous catheter tips. The cavoatrial junction, however, has still not been clearly defined in the central venous access or medical imaging literature, resulting in controversy and confusion.

Azygous arch: The cephalad aspect of the azygous arch at the junction of the azygous vein with the SVC as viewed in the coronal plane. Atriocaval junction: The caudad margin of the SVC as defined by the level below which the cylindrical SVC flares into the right atrial chamber.

Radiographic Findings with Central Venous Catheters
The optimal location of a central venous catheter tip is the cavoatrial junction. Acceptable locations include: Superior vena cava (including brachiocephalic - SVC junction) Right atrium. Inferior vena cava. Central venous catheter tip at cavoatrial junction. Central venous catheter tip at brachiocephalic - SVC junction.
