Which term describes a procedure to visualize the heart using a catheter?

• A. CARDIAC CATHETERIZATION
• B. HEMIPLEGIA
• C. SEMI-
• D. HALF

Answer: (A)

The concept being tested is recognizing the term for a catheter-based method to image the heart. Cardiac catheterization involves threading a thin tube through a blood vessel into the heart and injecting contrast dye so the heart’s chambers, valves, and coronary arteries can be seen clearly on imaging. This procedure not only visualizes the heart’s anatomy but also allows measurement of pressures and assessment of function, and it can be used therapeutically for interventions like angioplasty. The other options don’t describe a heart-imaging procedure: hemiplegia is paralysis of one side of the body, and semi- or half are prefixes that don’t refer to a specific diagnostic procedure.
