Characteristics of FINE Fundamental in Determining Whether the Fetal Heart Is Abnormal and in Determining the Specific Cardiac Diagnosis

Characteristic	FINE
General	Automatic realignment of STIC volume and reorientation and standardization of the anatomic position so that the fetus and cardiac diagnostic planes are consistently displayed in the same manner each time
No manual navigation	• Manual standardization or manipulation of the STIC volume data set and reference planes is not required (eg, alignment or rotation) • Reduced operator dependency • Examination of the fetal heart is standardized and simplified
STICLoop	While the 2‐dimensional cine loop is automatically scrolling in a continuous fashion, abnormal cardiac anatomy is often displayed
Marking of anatomic structures within the STIC volume	During the marking process, sometimes it is evident that: (1) anatomic structures are absent; (2) anatomic structures are not in their usual location; or (3) marking anatomic structures is difficult. One explanation is the presence of CHD
Cardiac diagnostic planes	• All 9 planes (including transverse and sagittal) are displayed simultaneously in a single template • Various features of the CHD can be visualized and compared side‐by‐side (eg, overriding aorta, ventricular septal defect, pulmonary stenosis in tetralogy of Fallot) • The same specific abnormality can be confirmed in multiple echocardiographic views at the same time (eg, hypoplasia of the pulmonary artery seen in the 3VT view, short‐axis view of great vessels/right ventricular outflow tract, and ductal arch view)
VIS‐Assistance	• Depiction of cardiac abnormalities when the diagnostic plane appears normal • Provides further diagnostic information even when the diagnostic plane is abnormal • Changes a suspected abnormal fetal echocardiographic view to one that is interpreted as normal • Improves the success of obtaining the fetal echocardiographic view of interest when this is not initially obtained via the diagnostic plane • Double, triple VIS‐Assistance techniques
Automatic labeling	Assists in identification of fetal echocardiographic views, anatomic structures (atrial and ventricular chambers, great vessels, venae cavae and stomach), left and right side of fetus, and cranial and caudal ends
Color Doppler FINE	Depicts abnormal fetal cardiac anatomy and/or hemodynamic flow characteristics

3VT indicates 3 vessels and trachea.
