Figure 2

Stretch by quadrant for volunteers and patient groups. The overall stretch was 106% for the volunteers, 103% for the non-dilated BAV patients, and 101% for the dilated patient group. Patients with dilated aorta had a decreased overall stretch compared to non-dilated aortas. The volunteers show the greatest difference in stretch between the posterior and anterior quadrants (p < 0.05) while the non-dilated BAV patients had the greatest stretch in the right quadrant and the least stretch in the anterior quadrant (p < 0.001).
