Which indication involves evaluating the function of the left ventricle?

Which indication involves evaluating the function of the left ventricle?

• A. Evaluate LV function
• B. Identify and determine the extent of CAD
• C. Assess valvular heart disease
• D. Obtain myocardial biopsy

Answer: (A)

Evaluating how the left ventricle contracts and pumps blood—its systolic function—is what this item is about. This involves measuring parameters like ejection fraction, LV volumes, and regional wall motion, often obtained during left heart catheterization with left ventriculography. That direct assessment of ventricular performance is what the indication seeks. The other options target different goals: identifying how blocked or narrowed the coronary arteries are (CAD), assessing valve function and gradients (valvular disease), or obtaining tissue for pathology (myocardial biopsy).
