    Abstract:
    Clinical and angiographic features and transesophageal echocardiographic (TEE) findings were retrospectively analyzed in 105 consecutive patients with valvular heart disease to assess the value of TEE detection of thoracic aortic plaque for predicting coronary artery disease. In 19 patients with significant coronary artery stenosis (> or = 70% narrowing of the luminal diameter in the left anterior descending, left circumflex, or right coronary arteries, or > or = 50% stenosis of the left main coronary artery), 18 had thoracic aortic plaque on TEE study. In contrast, aortic plaque existed in only 10 of the remaining 86 patients with normal coronary arteries or mildly atherosclerotic coronary lesions. The presence of aortic plaque on TEE study had a sensitivity of 95% and a specificity study had a sensitivity of 95% and a specificity of 88% for significant coronary stenosis at angiography. The positive and negative predictive values were 64% and 99%, respectively. There was a close relation between the degree of aortic intimal changes and the severity of coronary artery disease (r = 0.65; p < 0.001). Multivariate stepwise regression analysis of patient age, sex, risk factors of cardiovascular disease, angina, and TEE findings revealed that atherosclerotic aortic plaque was the most significant independent predictor of coronary artery disease. This study indicates that TEE detection of atherosclerotic plaque in the thoracic aorta is useful in the noninvasive prediction of the presence and severity of coronary artery disease in patients with valvular heart disease.
