Left Heart Chamber Volumetric Assessment by Automated Three-Dimensional Echocardiography in Heart Transplant Recipients

Abstract: BackgroundRecently, a new automated software (Heart Model) was developed to obtain three-dimensional (3D) left heart chamber volumes. The aim of this study was to verify the feasibility and accuracy of the automated 3D echocardiographic algorithm in heart transplant (HTx) patients. Conventional manual 3D transthoracic echocardiographic (TTE) tracings and cardiac magnetic resonance (CMR) images were used as a reference for comparison.MethodsThis study enrolled 103 healthy HTx patients prospectively. In protocol… Show more

“…These ndings were consistent with previous studies 15 . Some factors might keep it from realizing its full potential: 1) poor image quality, which is associated with less agreement and greater bias of GLS measurement results 18 , 2) displacement and distorted anatomy of the transplanted heart, which make it di cult for automated analysis software to recognize heart shape and endocardial border, for automated analysis depends on knowledge-based identi cation of normal cardiac anatomy 19 . Automated LVGLS showed greater producibility and e ciency than semiautomated and manual LVGLS, taking prognostic value and measuring accuracy of semiautomated LVGLS into consideration, it is possible to apply this automated method in daily clinical practice.…”
