Key result
Maternal obesity linked to an ~89% higher rate of suboptimal fetal CV ultrasound visualization.
Why the study?
The impact of maternal BMI on ultrasound visualization of fetal morphology was not well characterized.
Does maternal obesity increase suboptimal fetal anatomic ultrasound visualisation in singleton pregnancies?
Comparison
Obese maternal BMI (>30 kg/m2) vs normal maternal BMI (18.5-24.9 kg/m2)
Design
Observational cohort study

May necessitate protocol modifications for obese patients; confirms association in singletons but leaves open effects on diagnostic accuracy.
Observational (n=814)
Does maternal obesity increase suboptimal fetal anatomic ultrasound visualisation in singleton pregnancies?
Absolute Event Rate: 50.9% vs 26.9%
p-value: p=< 0.0001
Maternal obesity significantly increases the frequency of suboptimal fetal anatomic ultrasound visualisation, particularly for the cardiovascular system, facial soft tissue, and abdominal wall.
Khoury et al. (2008) conducted an observational in Singleton pregnancies (n=814). Maternal obesity (BMI >30 kg/m2) vs. Normal BMI (18.5-24.9 kg/m2) was evaluated on Suboptimal visualisation of the cardiovascular system (p=< 0.0001). Maternal obesity significantly increased the frequency of suboptimal fetal cardiovascular ultrasound visualization compared to normal weight (50.9% vs. 26.9%, p < 0.0001).
