LEFT VENTRICULAR LAYER-SPECIFIC STRAIN BY 2D SPECKLE-TRACKING ECHOCARDIOGRAPHY IN PEDIATRIC MYOCARDITIS

Öz

Introduction: Myocarditis is an inflammatory disease of the myocardium with variable clinical presentation and challenging diagnosis, particularly in children with preserved left ventricular ejection fraction. Layer-specific strain analysis using speckle-tracking echocardiography allows separate assessment of endocardial, mid-myocardial, and epicardial deformation. We aimed to evaluate layer-specific strain in pediatric patients with acute myocarditis to determine whether layer-specific deformation parameters detect subclinical myocardial dysfunction. Results: Twenty-one pediatric patients with acute myocarditis (mean age 188.1 ± 22.8 months; 17 male) and 20 age- and sex-matched healthy controls were enrolled. Two-dimensional and speckle-tracking echocardiography with layer-specific strain analysis were performed. Global longitudinal strain and layer-specific longitudinal strain were measured at basal, mid-ventricular, and apical levels in endocardial, mid-myocardial, and epicardial layers. Patients with myocarditis had lower left ventricular ejection fraction compared to controls (%63 ± 3.4 vs %71.2 ± 1.9, p<0.001). Global longitudinal strain was reduced in the myocarditis group (-18.8 ± 3.1% vs -21.6 ± 1.9%, p=0.032). All three myocardial layers showed reduced longitudinal strain in patients compared to controls: endocardial (-21.6 ± 3.5% vs -24.4 ± 2.6%, p=0.033), mid-myocardial (-18.8 ± 2.7% vs -21.4 ± 3.2%, p=0.040) and epicardial (-16.8 ± 2.6% vs -19.5 ± 1.6%, p=0.008). Discussion: Layer-specific strain analysis by speckle-tracking echocardiography detects subclinical myocardial dysfunction in pediatric myocarditis even when left ventricular ejection fraction is relatively preserved. The differential involvement of myocardial layers, particularly epicardial impairment, reflects the known subepicardial predominance of inflammatory injury in myocarditis. Layer-specific strain may provide incremental diagnostic value over conventional echocardiography in this population.

The study was approved by Kocaeli University Non-Interventional Research Ethics Committee. Approval number is KÜ GOKAEK-2026/04/46 and approval date is 12.02.2026. All patient data were handled in compliance with institutional and national data protection regulations. Identifying information was removed, and only anonymized data were used for analysis. Access to the data was restricted to authorized study personnel. Because this study was based on a retrospective review of existing medical records and did not involve direct patient contact, individual informed consent was waived by the institutional ethics committee
