Aortocoronary bypass grafting in a child with coronary artery obstruction due to mucocutaneous lymphnode syndrome: report of a case.
A four-year-old boy with a myocardial infarct and total occlusion of the right coronary and the left anterior descending coronary arteries due to mucocoutaneous lymphnode syndrome (MCLS). confirmed by selective coronary arteriography, underwent successful double aortocoronary bypass grafting. Patency of the grafts was demonstrated by graft angiography and the improvement of the contractile pattern of the left ventricle was reflected by the increase in ejection fraction from 0.45 to 0.61. This is the first patient successfully treated by aortocoronary bypass grafting for coronary artery obstructive lesions due to MCLS. This experience has demonstrated the feasibility of surgical management in a child with coronary artery obstruction due to MCLS. However, there are unanswered questions regarding the fate of the saphenous vein graft in relation to the growth of a child. Long-term clinical and angiographic follow-ups are mandatory to determine the significance of this mode of surgical treatment for the sequela of MCLS.
