- Abstract
Cardiac and arterial function is reflected in the distension (change in diameter) waveforms of central arteries.
For analyses, commonly the distension waveform of the common carotid artery (CCA) is used, as the CCA is superficial and easily accessible with ultrasound (US). However, the abdominal aorta (AA) is directly connected to the aortic root and a more pronounced influence of cardiovascular diseases on the AA pulse waveform is expected. The aim of this study is to compare the pulse waveforms in AA and CCA.
For this purpose, simultaneous assessment of the distension waveforms in the AA and CCA are performed on three healthy volunteers using two ultrasound scanners with ART.LAB functionality (Picus, Esaote Europe). The two systems are synchronised using ECG triggering. In addition, radial blood pressure is recorded continuously (Colin, USA).
Results show, that AA and CCA distension could reproducibly be measured. The ejection periods of the heart assessed from these pulse waves are equal. The maximum wall velocity is about 2.5 times higher in AA than in CCA. Approximated local blood pressure pulse is higher in AA than in CCA (58 mmHg and 44 mmHg respectively). Local pulse wave velocities, based on the distensibility coefficient, only slightly differ.
Future research will focus on analyzing the differences between both pulse waveforms with a 1D wave propagation model.
