Classifying Cardiac Anomalies in Right and Left Isomerism: Concordant and Discordant Patterns

Aims: Evidence is emerging that, in the setting of isomerism, atrial and bronchial arrangement are not always concordant, nor these patterns harmonious with abdominal organs. We aimed to evaluate concordance between features a cohort patients cardiac malformations known seeking determine whether it was feasible assess complexity on this basis, regard taking note potential value as opposed appendage morphology. Methods Results: studied 78 have isomerism bronchuses, 43 right 35 left isomerism. Appendage anatomy could be determined 49 cases (63%), all but one being concordant anatomy. When assessing features, only 59 (76%) splenic morphology keeping thoracic findings. As expected, associated greater malformations, an odds ratio 6.53, confidence intervals from 2.2–19.3 (p < 0.001). The were slightly decreased thoraco-abdominal disharmony, when lesions shown carry higher risk then found Conclusion: Harmony excellent less so Right our cohort, indicative six-fold increase intracardiac complexity. discordance systems, however, anomalies typical anticipated findings for vs. appendages.
