Abstract:
Objective: To observe the value of real-time three-dimensional transesophageal echocardiography (3D-TEE) in diagnosing aortic dissection and evaluating coronary artery and aortic root involvement. Methods: Data of 3D-TEE, two-dimensional transthoracic echocardiography (2D-TTE) and CTA in 30 patients with aortic dissection were retrospectively analyzed and compared with operative findings, and the accordance rate of the three techniques in classifying aortic dissection, as well as of 3D-TEE and CTA in assessment of aortic root and coronary artery involvement were evaluated. Results: The diagnostic coincidence rate of 3D-TEE and CTA in classifying aortic dissection Debakey , Ⅱ, III type were all 100%, of 2D-TTE in Debakey was 76.47% (13/17), in Debakey Ⅱ was 80.00% (4/5) and in Debakey III was 75.00% (6/8). The coincidence rate of 3D-TEE in assessment of coronary artery involvement was 66.67% (4/6), and of CTA was 83.33% (5/6). The coincidence rate of 3D-TEE in assessment of aortic root involvement was 100% (11/11), and of CTA was 72.73% (8/11). Conclusion: Real-time 3D-TEE can perform real-time dynamic three-dimensional reconstruction of aortic dissection, aortic root, coronary artery and other parts, and provide imaging support for diagnosis of aortic dissection and assessment of important anatomical structures.
