SDTM. Circumferential & Longitudinal Strain

Check with team and CT - these are different than the 17 segments in the other example. Not sure if these can be generalized to the heart or if the locations need to be specific by ventricle (seems like but I am not sure). It may indicate the view of 4 chambers from the left ventricular wall side (left ventricle, 4 -chamber). Need to know which one to use.

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