Popis: Coronary angiography remains the standard for diagnosis of cardiac transplant vasculopathy (CAV), but it is invasive. Non-invasively derived left ventricle (LV) global myocardial work (GMW) indices have not been evaluated. We aimed to assess for correlations between LV GMW and the presence of CAV in a pediatric population. 24 heart transplant patients and 24 normal controls were prospectively enrolled. Patients were age-matched into groups with: orthotopic heart transplant and CAV (OHT-CAV; 6 patients, 33% male, mean age 13.5 years [SD 4.2]), orthotopic heart transplant without CAV (OHT; 18 patients, 67% male, mean age 11.1 years [SD 4.8]), and normal healthy controls (42% male, mean age 12.8 years [SD 5.0]). Transplant patients underwent cardiac catheterization with coronary angiography within 3 months of echocardiogram. Post-processing of echocardiograms with speckle-tracking echocardiography and derivation of GMW indices was performed. OHT-CAV patients had decreased global work efficiency (GWE) compared to OHT (mean difference = 7.01 [1.76, 12.25], adjusted p
