Impact of transesophageal echocardiography on the treatment of patients with aortic dissection.
To determine the impact of transesophageal echocardiography (TE) on the treatment of patients with aortic dissection, the clinical course and outcome of 18 patients with TE diagnosis of dissection were analyzed. Ascending aortic dissection was present in nine patients, of whom six had surgery with confirmation of TE findings. Angiography was performed in only two of these patients and was falsely negative in one patient. Angiography was not performed in the three patients who were not surgical candidates. In the nine patients who had descending aortic dissection, angiography was performed in seven patients, of whom two underwent surgery. Information provided by angiography did not change the treatment of these patients. Thus, TE provides a prompt and accurate diagnosis in aortic dissection obviating the need for angiography in most patients.
