Nomograms Based on Myocardial Strain and Myocardial Work to Predict Low Cardiac Output Syndrome in Children Undergoing Surgery for Congenital Heart Disease
Authors' conclusion
We developed a nomogram model incorporating GLS, GWI, and GWE to predict postoperative LCOS in children undergoing CHD surgery. The model demonstrated favorable discrimination, calibration, and clinical applicability
