Subclavian-coronary artery anastomosis in infancy for the Bland-White-Garland syndrome: a three-year and five-year follow-up.
Two infants, 4 months and 8 months of age, with anomalous origin of the left coronary artery, underwent direct anastomosis of the left subclavian artery to the left coronary artery. In the patient operated upon at 4 months of age, the anastomosis proved to be patent by angiographic study 3 years postoperatively. However, in the patient operated upon at 8 months of age, the study 5 years postoperatively revaled clinically unsuspected occlusion at the anastomosis site. After operation, both patients symptomatically improved. The heart size decreased on radiograms, the left ventricular ejection fraction improved, and the electrocardiographic abnormality resolved to a great extent. Since the preferred treatment for this abnormality and the ideal age for operation are yet to be established, long-term angiographic follow-up of all such surgically treated patients is needed. An advantage of the subclavian-coronary artery anastomosis is its applicability in the infant.
