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

• A. Percutaneous femoral artery
• B. Radial artery
• C. Brachial artery
• D. Carotid artery

Answer: (A)

Access to the arterial system is required to perform a left heart catheterization, and the femoral artery is the standard entry point because it readily accommodates the larger diagnostic catheters and sheaths and provides a relatively straight path up the aorta to the aortic root and coronary arteries. It also allows reliable compression afterward if bleeding occurs. While radial access is increasingly used and offers lower bleeding risk in many cases, the femoral route remains the default in many labs due to its size and ease of use for left heart work. The brachial or carotid routes carry higher risks of complications and are less favored. So, the percutaneous femoral artery is the most common insertion site.
