During right heart catheterization, which chamber was angiographed?

During right heart catheterization, the primary focus is on the right side of the heart, particularly the right atrium. This procedure is typically performed to measure hemodynamic parameters, including pressures in the heart and lungs, and can also involve visualizing the structures of the right heart chambers.

When the catheter is inserted, it usually enters the venous system and travels to the right atrium, where angiography may be performed to assess various conditions such as right heart failure, chamber enlargement, or congenital heart defects. The imaging obtained during this process helps to provide a clear visualization of the heart's anatomy and any abnormalities present.

The other options reflect chambers on the left side of the heart or chambers not primarily focused on during right heart catheterization, which is specifically concerned with the right atrium and right ventricle. Thus, the choice of the right atrium aligns well with the procedures and objectives of right heart catheterization.
