Right heart ventriculography is a study of the right chambers (atrium and ventricle) of the heart. This test obtains measurements of pressure, oxygen, and cardiac output through a catheter (thin flexible tube).
Occasionally, the right chambers also need to be seen. This can be done by injecting contrast material through the catheter into the right side of the heart and taking a rapid succession of x-rays to capture images of blood flow.
