2. Right Heart Catheterization

Right heart catheterization is a medical procedure used to measure the pressure and blood flow in the right side of the heart and its major blood vessels. A thin, flexible tube called a catheter is inserted through a vein, often in the neck or groin, and guided to the heart. This test helps doctors diagnose conditions like heart failure, lung diseases, or congenital heart defects by providing critical information about how well the heart is functioning and how well blood is circulating in the body. It is typically performed in a hospital setting.
