摘要: Abstract Background . The presence of ascending aortic atheroma is a known risk for systemic emboli or early saphenous vein graft failure if unrecognized at the time cardiopulmonary bypass. Methods This study prospectively compared intraoperative omniplane transesophageal echocardiography (TEE) and epiaortic ultrasound (EAU) images in 22 patients (6 women, 16 men, age 66 ± 8 years) before surgical manipulation aorta. Atheroma lesion severity was scored: 1=normal, 2=nonprotruding intimal thickening (> 2 mm), 3=atheroma less than 4 mm Ca++, 4=atheroma greater equal to 5=any size mobile ulcerated Ca++. aorta between valve innominate artery divided into proximal, middle, distal segments. A total segments were evaluated. Results Although overall agreement scores procedures 75.8%, significantly more lesions identified by EAU (15) TEE (5) ( p Conclusions atheromatous both modalities, results suggest that may have an advantage over surgeons assessing target sites involving
