BACKGROUND: Myocardial perfusion is not completely normal and ventricular function is depressed in some patients after the arterial switch operation. The basic mechanism has not yet been defined totally.
METHODS: The diameters of the right, left main trunk, anterior descending, and circumflex coronary arteries were measured by computer-assisted densitometry at 8 to 86 months (mean, 47.5 months) after the arterial switch operation in 86 patients.
RESULTS: The Z scores, compared with control, were +2.0 +/- 0.3, -1.8 +/- 0.3, and -1.5 +/- 0.3 for the right, left anterior descending, and circumflex coronary arteries, respectively. The Z score for the total cross-sectional area of the three vessels was -1.5 +/- 0.3. These parameters did not correlate with left ventricular ejection fraction.
CONCLUSIONS: At the midterm follow-up after the arterial switch operation for complete transposition of the great arteries, the left coronary arteries are small. A careful follow-up study is mandatory to clarify the clinical significance of this finding.
