What does three-dimensional echocardiography improve in relation to regurgitation?

• A. 3D echo is not helpful for regurgitation assessment.
• B. 3D echo replaces all Doppler methods.
• C. 3D echo improves quantification of regurgitant orifice area and vena contracta.
• D. 3D echo is only used for LV volumes.

Answer: (C)

Three-dimensional echocardiography enhances regurgitation assessment by letting you directly measure the regurgitant orifice area and the vena contracta. In many valves, the regurgitant orifice is irregular, dynamic, or even multi‑orifice, and a single 2D plane or a width measurement can misrepresent the true cross‑sectional area. With 3D color Doppler, you can view the orifice en face during systole and planimetrically trace its true orifice area, yielding a more accurate regurgitant orifice area and vena contracta. This improves grading of severity, especially for eccentric jets or complex lesions. Doppler velocity data remains essential and 3D does not replace all Doppler methods. It also adds value beyond LV volumes, though it is not limited to them.
