Abstract
Transesophageal echocardiography (TEE) is widely used for the evaluation of aortic arch atherosclerosis which carries an increased risk of ischemic stroke. We investigated the feasibility of simultaneous multi-plane imaging by real-time 3-D TEE for the assessment of aortic arch plaques. In 152 patients, we assessed aortic arch plaques and measured their maximum thickness by both conventional TEE imaging and multi-plane TEE imaging. There was excellent correlation and good agreement between the two methods in the measurement of the maximum thickness of arch plaques (r = 0.95, mean difference, â0.1 ± 0.5 mm). The mean image acquisition time required for aortic arch assessment by multi-plane imaging was significantly shorter than that required for conventional imaging in all patients (p < 0.001), especially those with complex plaques. These findings suggest that simultaneous multi-plane TEE imaging enables rapid and accurate evaluation of arch plaques and is therefore a useful tool for the assessment of aortic arch plaques in the clinical setting.
