title: Coronary collaterals by transthoracic echocardiography in coronary artery disease.
abstract: Demonstration of coronary collaterals has been mostly done by coronary angiographic techniques. Coronary collaterals have been demonstrated by transthoracic echocardiography for patients with anomalous origin of coronary arteries from pulmonary artery. Indirect assessment of collaterals to an infarct-related artery has been done using myocardial contrast echocardiography. We describe in this article 3 patients with coronary artery disease in whom coronary collaterals were demonstrated by transthoracic echocardiography before angiography. To our knowledge, coronary collateral demonstration by transthoracic echocardiography before angiography in patients with coronary artery disease has not been previously reported.
