title: [Coronary ostial stenosis after an aortic valve replacement diagnosed by transesophageal echocardiography].
abstract: We submit the case of a 75-year-old man that underwent aortic valve replacement whose preoperative coronary angiography showed lesion-free coronaries. Two months after surgery he began to feel rapidly progressing effort angina pectoris. Transesophageal echocardiography showed prosthetic normal function while allowing the study of the great coronary trunks. We observed the presence of a 50% stenosis at the ostium of the left coronary artery trunk due to the use of selective coronary cannulation to supply cardioplegia solution during valve replacement. A second coronary angiography confirmed this finding. Transesophageal echocardiography may be used as an initial diagnostic method when coronary ostial stenosis is suspected after aortic valve replacement.
