Changes in aortic vortex flow pattern may closely correlate with degree of arteriosclerosis. The aim of study was to characterize aortic vortex flow pattern by transesophageal contrast echocardiography in normals and patients with cardiovascular risk.
A total of 30 patients with hypertension and 10 controls were recruited for this study. The 10 controls were designated Group 1. Group 2 consist of 15 hypertensive patients without cardiovascular events. Group 3 consist of 15 hypertensive patients with stroke or coronary artery disease. All patients underwent contrast transesophageal echocardiography for assessing aortic vortex flow analysis. Vortex flow morphology, location, phasic variation and pulsatility were analyzed and compare between three groups.
In normal, multiple elliptical vortices with high pulsatility were observed in descending aorta. In group 2, single, merged round vortex was observed in the center of aorta with high pulsatility. In contrast, group 3 showed round merged vortex with lower pulsatility in periphery of aorta. Phasic variation of aortic vortex size is significantly decreased in group 3 compare with group 1 and 2(58.8 ± 23.5 and 54.3 ± 19.2 vs. 37.5 ± 15.4, p < 0.001). Figureshows example of aortic vortex flow pattern between three groups.
Characterization of aortic vortex flow using contrast echocardiography was feasible and vortex flow pattern was significanty different between normals and patients with cardiovascular risk.
