Regular antegrade blood flow pattern.

<p>A-C show a regular contrast agent inflow during implantation of a port-catheter into the right atrium (arrow tip) via the right jugular vein. Thus, in A only the right atrium contains contrast agent, which then flows via the pulmonary arteries into the lung (B), and finally contrasts the left ventricle, the aortic arch as well as the supraaortic arterial vessels (C). A repeat DSA with regular contrast agent flow was performed in the same animal 2 weeks later (D-F).
