The thoracic aorta is less stiff than the abdominal aorta in young and middle-aged subjects, and stiffens more rapidly with age than the abdominal aorta, resulting in a stiffer thoracic than abdominal aorta at older age.

The travelled cf path is slightly longer at the right than at the left body side and the straight MRI distance tends to perform better than tape measure distance. The present study supports the advice of the expert consensus group to measure cf-PWV at the right body side using a sliding caliper when tape measure distance cannot be obtained in a straight line.

background: A 34-year-old man presented with recurrent and intermittent painful hydrops of the knee. This has started 13 years ago, after he underwent a reconstruction of the anterior cruciate ligament (ACL) and a partial resection of the lateral meniscus. Clinical examination revealed marked swelling due to the hydrops.
