However, their reliability in children following cardiac surgery involving pericardiotomy remains unclear. The goal of this study was to evaluate whether TAPSE and FAC are valid surrogate markers of global RV systolic function in paediatric patients with and without prior pericardiotomy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We retrospectively analysed 120 paediatric patients who underwent ferumoxytol-enhanced, motion-resolved five-dimensional whole-heart cardiac MRI between 2020 and 2024. Patients were divided into two groups: those who had previous pericardiotomy (n=85) and those who had no previous surgery (n=35). TAPSE z-scores, RV FAC and RV ejection fraction (RVEF) were measured and compared between the two groups and correlation analyses were performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In the post-pericardiotomy group, TAPSE z-score was significantly decreased (\u22125.32\u00b12) and did not correlate with RVEF (r=0.04), while RV FAC was preserved (41.3%) but correlated only weakly with RVEF (r=0.39). In patients without previous cardiac surgery, TAPSE z-score was within the normal range (0.17\u00b11.48) but demonstrated a weak correlation with RVEF (r=0.28), while RV FAC was moderately correlated with RVEF (r=0.57). Differences in the correlation strengths between the two groups were not statistically significant.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>TAPSE and RV FAC showed limited reliability as surrogate markers of global RV systolic function in paediatric patients especially following surgery involving pericardiotomy.
