right heart ventriculography
A right heart ventriculography is a study of the right chambers of the heart (the right atrium and right ventricle). The test helps physicians measure pressure, oxygen and cardiac output through a thin flexible tube called a catheter. Occasionally, visualizing the right chambers is also necessary. This is done by injecting contrast media (dye) through the catheter into the heart's right side with a rapid succession of X-rays taken to capture images of blood flow.
