INTRODUCTION: Coronary arteriography remains a gold standard for the evaluation of coronary anatomy. In the case of anatomical anomalies, understanding of vessel course based upon a coronary angiogram may be difficult. Transesophageal echocardiography is a noninvasive method allowing tomographic visualization of proximal coronary arteries. Experience concerning its usefulness for the assessment of anomalous coronary arteries is limited.
MATERIAL: Eleven patients with confirmed coronary anomalies studied between 1993-96 were identified in the cohort of those undergoing transesophageal echocardiography.
RESULTS: Transesophageal echocardiography revealed potentially serious anomalies (origin of left or right coronary artery from contralateral aortic sinus) in 3 patients and benign in 8. Coronary ostia and proximal course could be delineated in all patients. Anatomical information was consistent between methods, except for a separate origin of the left anterior descending and circumflex artery, where the angiogram missed a very short common left main coronary artery in 2 patients. The relationship between the coronary arteries, aorta and pulmonary trunk was better defined by the echocardiogram. Doppler flow analysis allowed us to exclude anomaly-related flow disturbances.
CONCLUSIONS: Transesophageal echocardiography can be considered as a noninvasive technique with the potential for anatomical and functional evaluation of anomalous proximal coronary arteries and deserves a routine use whenever such a condition is suspected. This approach may simplify invasive procedures in this patient group.
