Evaluation of Three-Dimensional Laser Scanning for Precise Measurement of Lower Limb Edema in Heart Failure Patients
Overview
This feasibility study evaluates three-dimensional laser scanning (3DLS) for measuring lower limb edema in heart failure patients. The findings indicate that 3DLS shows significant correlation with traditional circumferential methods.
Background
Lower limb edema is prevalent in older adults with heart failure, impacting their physical well-being and functional capacity. Accurate measurement of edema is crucial for effective management and treatment. Traditional methods, such as circumferential measurement, may lack the precision needed for optimal clinical decision-making.

Key Findings
3DLS demonstrated significant correlations with traditional circumferential measurement (CM).
DELA VERT-3DLS method had the highest correlation (r = 0.856; p < 0.001).
Bland–Altman analysis indicated a trend of overestimation among digital methods compared to CM.
The study involved 8 heart failure patients with a mean age of 73 years.
Further studies with larger cohorts are needed to confirm the feasibility and reliability of 3DLS.
Clinical Implications
Further studies are needed to explore the clinical applicability of 3DLS for assessing lower limb edema in heart failure patients.
Conclusion
The preliminary results indicate that further research is necessary to validate these findings in larger populations.
