Where are the typical insertion sites for a cardiac catheterization?

• A. An artery or vein in the arm, neck, or groin
• B. Only the femoral artery
• C. Only the internal jugular vein
• D. Only the radial artery

Answer: (A)

Access to the heart during catheterization is gained through large vessels, and the route can be arterial or venous. Common entry points include vessels in the groin (femoral artery or femoral vein), in the arm or wrist (radial or brachial arteries or veins), and in the neck (internal jugular vein). Left-heart studies typically use arterial access, often via the femoral or radial artery, while right-heart studies use venous access, such as the femoral or internal jugular vein. Describing an artery or vein in the arm, neck, or groin captures the typical, versatile sites used in practice. Focusing on a single site or region would miss this broader, standard availability, which is why the broader description is the best choice.
