Left ventriculography provides which information?

Left ventriculography provides which information?

• A. Aortic valve calcification grade.
• B. Pulmonary arterial pressures.
• C. LV size, regional wall motion, LV function, and ejection fraction.
• D. Coronary lumen diameter.

Answer: (C)

Left ventriculography during left-heart catheterization is used to directly image the left ventricle as contrast fills the chamber. This allows assessment of how big the ventricle is (LV size), how the walls move in different regions (regional wall motion), overall pumping ability (LV function), and the amount of blood pumped out with each beat (ejection fraction). These elements come from visualizing the LV’s shape and contractile activity on cineangiography and from calculating volumes to derive the EF. Aortic valve calcification grade isn’t obtained from this study—it’s usually evaluated with echo or CT. Pulmonary arterial pressures require right-heart catheterization. Coronary lumen diameter is assessed with coronary angiography, not LV ventriculography.
