What is the most common insertion site for a right heart catheterization?

• A. Femoral vein
• B. Radial artery
• C. Carotid artery
• D. Subclavian vein

Answer: (A)

Right heart catheterization uses venous access to reach the right atrium and measure right‑sided pressures. The femoral vein is the most common insertion site because it provides a large, easy-to-puncture pathway that leads directly into the inferior vena cava and then into the right atrium. This makes catheter advancement straightforward and reduces arterial-related risks. The radial artery is an arterial access point, not used for right heart catheterization. The carotid artery is also arterial and carries high stroke risk, so it’s not appropriate. The subclavian vein is a venous option and can be used in some cases, but historically it’s less preferred than the femoral route due to factors like pneumothorax risk and patient treatment considerations.
