Objective: To assess the viewing rate and reproducibility of areas of the papillary muscles (PMs) of foetal atrioventricular valves using spatio-temporal image correlation (STIC) in the rendering mode in congenital heart disease (CHD).Methods: We retrospectively reviewed 40 4D-STIC volume datasets from different foetal CHD cases at a gestational age of 18w6d–35w6d. The following papillary muscles (PMs) were assessed: antero-lateral (MPAL) and postero-medial (MPPM) to the mitral valve and antero-superior (MPAS), inferior (MPI) and septal (MPS) to the tricuspid valve. To assess the valve viewing rate, percentages (%) were used. The concordance correlation coefficient (CCC) was used to assess inter-observer reliability.Results: Two independent observers concluded that a complete examination of the PMs was impossible in 11 cases, yielding a viewing rate of 72.5%. The complete examination of the PMs of the tricuspid and mitral valves was possible by both examiners in 33/40 (82.5%) and 32/40 (80.0%) cases, respectively. We observed moderate to good inter-observer reliability with CCCs of 0.95, 0.92, 0.97, 0.96 and 0.97 for MPS, MPI, MPAS, MPAL and MPPM, respectively.Conclusion: The viewing rate of PM areas in different CHDs using STIC in the rendering mode was moderate. The inter-observer reproducibility was moderate to good for all PM areas. [ABSTRACT FROM AUTHOR] |
