Why the study?
Does offline anatomic M-mode (AMM) provide comparable measurements of fetal atrioventricular annulus long-axis displacement (LAD) compared to real-time conventional M-mode (MM) in normal singleton pregnancies?
Population
91 normal singleton pregnancies, including a subset of 54 fetuses with paired AMM and MM LAD studies.
Comparison
Offline anatomic M-mode for measuring fetal… vs Real-time conventional M-mode (MM)
Design
Cross-sectional

AMM correlates well with MM for fetal LAD; supports further validation but leaves open clinical interchangeability.
Does offline anatomic M-mode (AMM) provide comparable measurements of fetal atrioventricular annulus long-axis displacement (LAD) compared to real-time conventional M-mode (MM) in normal singleton pregnancies?
Offline anatomic M-mode is a feasible alternative to conventional M-mode for evaluating fetal longitudinal myocardial function, showing good correlation despite slightly higher measured values.
