SDTM. Circumferential & Longitudinal Strain

This example shows the representation of circumferential and longitudinal strain findings in the CV domain. The sponsor used the "CMRBRANDTYP Feature Tracking" analysis method (CVANMETH).

Rows 1-3:	Show circumferential strain for the left ventricle base, mid, and apex regions.
Row 4:	Shows circumferential strain for the LEFT VENTRICULAR BASAL INFEROSEPTAL SEGMENT.
Row 5:	Shows global circumferential strain.
Rows 6-8:	Show longitudinal strain for 4 chamber, 3 chamber, and 2 chamber views.
Row 9:	Shows longitudinal strain for the LEFT VENTRICULAR BASAL INFEROSEPTAL SEGMENT.
Row 10:	Shows global longitudinal strain.
