Echocardiography
Fig. 9. Aortic measurements by transesophageal echocardiography of mid esophageal aortic valve long-axis and the descending aortic short-axis (insert) still frames. Mild dilatation of the proximal ascending aorta is seen in this study.
Mid Aorta Dilation

Fig. 10. Midesophageal aortic valve long-axis views of a 69-yr-old male with a history of hypertension and paroxysmal atrial fibrillation. Moderate dilatation of the proximal aorta with a mobile dissection (intimal) flap were seen (arrows). Severe aortic regurgitation was present. He underwent total replacement of his aortic root with coronary artery re-implantation. (Please see companion DVD for corresponding video.)

Mid Ascending Aorta Measurement

Fig. 11. Further transthoracic echocardiography (TEE) descending aortic short axis views of the patient in Fig.10 revealed involvement of the entire thoracic aorta. This is therefore a Stanford type A or Debakey type I aortic dissection (Fig. 4). Note color flow Doppler pattern within the true lumen (TL) and the false lumen (FL) and pulsed Doppler interrogation revealing pulsatile flow within the true lumen. (Please see companion DVD for corresponding video.)
