Figure 1 : 

Tissue Doppler imaging in a patient after Fontan completion for hypoplastic left heart syndrome. (A) Pulse Doppler in the basal segment of the lateral wall with reduced systolic and diastolic velocities. (B) Simultaneous tissue Doppler velocities in six segments of the systemic ventricle. The absolute value for each segment is lower than the corresponding pulse Doppler velocity. (C and D) Tissue Doppler-derived strain and strain rate for the same ventricle with abnormal curves for the septal segments (not involved in ejection).

Figure 2 : 

Longitudinal strain in a patient with dilated cardiomyopathy and severely impaired systolic function. It is easy to appreciate the presence of dyskinetic motion and postsystolic shortening of some segments. The global longitudinal strain is severely reduced.

Figure 3 : 

Hypertrophic cardiomyopathy with preserved longitudinal function but abnormal rotation pattern with counterclockwise rotation of both apex and base.

Figure 4 : 

Three-dimensional volumetric assessment of the left heart using one of the commercially available pieces of software. (A) Segmental analysis of left ventricular volumetric change during systole. (B) Left atrial volume.

Knowledge-based three-dimensional reconstruction of right ventricular systolic and diastolic volumes in a patient after repair of tetralogy of Fallot; septal and anterior view of the right ventricle.
