- W1997507834 abstract "Although congenital heart defects (CHD) are the most common severe congenital malformation, they are often misdiagnosed. New technologies such as spatiotemporal image correlation (STIC) have been introduced with the aim of increasing prenatal CHD detection. To evaluate the possibility of performing a basic and extended cardiac examination from four-dimensional volume dataset acquired with STIC. STIC volumes of 295 pregnant women were acquired from a four-chamber view. Basic cardiac examination (BCE) (situs, four-chamber, five-chamber, outflow tracts, three-vessels and trachea, and interventricular septum) and complete echocardiography were assessed. Volumes were classified as normal or abnormal and the diagnoses were correlated with the standard 2D ultrasound examination. Mean gestational age at volume acquisition: 24.6 (range 15–40.6) weeks. Mean time of volume evaluation: 11 (range 1–40) min. A total of 110 CHD (37%) were diagnosed after STIC analysis. It was possible to perform a BCE from 87% of 4D volumes, although the four- and five-chamber views, the crossover of the great arteries and the three-vessel–trachea view were identified from 93% of the volumes acquired. The aortic and pulmonary arches as well as the pulmonary and systemic venous return were identified in 85% of cases. After 2D and STIC evaluation they were classified as normal or abnormal. There was a fairly good correlation between the diagnoses, showing a Kappa index value of 0.69 (P < 0.001). An appropriate cardiac evaluation can be offered from the analysis of a 4D volume dataset with an adequate correlation to 2D examination." @default.
