Compliance is an important physical property of the aorta, reflecting its ability to work as a buffer during the systolic phase of cardiac cycle. There is a great interest in studying ventriculoarterial interations and aortic properties like stiffness and distensibility in patients with congenital heart disease due to their ability to predict cardiovascular mortality . A surrogate marker of arterial stiffness is pulse wave velocity (PWV), which has been linked to prognostically adverse cardiac phenotypes in adults. There is little data on PWV in patients who have undergone single ventricle repair.
Our preliminary results suggest heightened PWV in SRV. However, the two plane method to estimate PWV is sensitive to placement of the acquisition plane along the neo-aorta, and may not be a reliable indicator of aortic stiffness. An alternative method that utilizes the long axis of the aorta to calculate PWV may provide greater reproducibility.
