| Popis: | Background Right ventricular (RV) volumetric and functional assessments are both crucial for the management of patients with hypoplastic left heart syndrome (HLHS). 3-dimensional echocardiography (3DE) for volume measurements and 2D speckle-tracking echocardiography (2D-STE) for strain analysis are performed separately. 3D-STE is capable of evaluating those parameters simultaneously and providing principal strain (PS), unifying the concepts of myofiber orientation and contraction into a single, maximal contractile direction. However, the application of 3D-STE to HLHS has not been studied and so became the aim of our study.Methods and Results:64 HLHS patients after Fontan palliation underwent 3D-STE analysis measuring RV end-diastolic volume index (EDVi), ejection fraction (EF), global PS (GPS), global circumferential strain (GCS), and global longitudinal strain (GLS). Volume measurements were compared between 3D-STE and 3DE, and strains were compared between 3D- and 2D-STE. EDVi and EF showed strong correlations between 3D-STE and 3DE (r=0.93 and 0.87, respectively). GCS and GLS showed moderate correlations between 3D- and 2D-STE (r=0.65 and 0.61, respectively). GPS showed highest magnitude and excellent correlation with EF (r=-0.95). Conclusions Simultaneous volumetric and functional assessment by 3D-STE was a useful method in this HLHS cohort. PS is a promising parameter for evaluating the RV function of HLHS, which could be useful during longitudinal follow-up. |
