What does a right atrial pressure of 12 mean from a right heart catheterization?

A right atrial pressure (RAP) of 12 mm Hg is elevated. This measurement indicates the amount of pressure in the upper-right chamber of your heart.

During right heart catheterization, doctors measure several pressures to understand how your heart and lungs are functioning. The RAP helps assess how well the right side of your heart is working and whether there's increased pressure affecting blood flow.

An elevated RAP can indicate that your heart is working harder than normal. This measurement is used alongside other readings like:

* Mean pulmonary arterial pressure (mPAP)
* Pulmonary vascular resistance
* Cardiac output
* Oxygen saturation

Your doctor will look at all these measurements together to understand the severity of your pulmonary hypertension and determine the best treatment approach. It's important to discuss what this specific reading means for your individual situation with your healthcare team, as they can explain how it fits into your overall cardiovascular health picture.
