Contrast angiography is the gold standard for the assessment of the site and severity of coronary artery narrowing. Transoesophageal echocardiography is recognized as a feasible technique in assessing coronary artery anomalies. Our patient had arteriosclerotic narrowing in a single right coronary artery with poor distal opacification during contrast injection. Combining transoesophageal echocardiography with contrast angiography helped us in visualizing a surgically accessible vessel on the anterior wall of the left ventricle.
