Abstract

Imaging fusion between echocardiography and fluoroscopy was recently developed. The aim of this study was to assess its feasibility and accuracy during pediatric cardiac catheterization. Thirty-one patients (median weight, 26 kg; interquartile range [IQR], 21-37 kg) who underwent percutaneous atrial septal defect closure were prospectively included. The feasibility and accuracy of various imaging fusion modalities (live two-dimensional, live color two-dimensional, live three-dimensional and markers) with EchoNavigator software were assessed. To assess the accuracy of spatial registration of the echocardiogram on the fluoroscopic image, the occluder screw, an object that appeared on each image, was used as a reference tool, and the distance between the two when fused was measured. A distance was measured on the fusion screen between a marker positioned on the screw from the echocardiography screen and from the fluoroscopy screen (distance 1). Another distance was measured on the fusion screen between the screw visualized by three-dimensional echocardiography and by fluoroscopy (distance 2). The two distances were measured on four C-arm orientations in end-systolic and end-diastolic frames. Fusion and marker positioning were feas...Continue Reading
