Mitral insufficiency secondary to mucocutaneous lymph node syndrome. A case report of successful surgical treatment.
A three-year-old girl with mitral regurgitation due to mucocutaneous lymph node syndrome (MCLS) but with normal coronary arteries was treated surgically. Although no definite pathologic lesions causing severe mitral regurgitation except for dilatation of the mitral annulus were found at operation, some minor changes implied focal ischemia of the posterior papillary muscle. A poster-medial annuloplasty was performed without significant residual regurgitation. This is the first patient successfully treated by surgery for mitral valve incompentence due to MCLS. However, additional clinical experiences will be needed to evaluate surgical treatment for this group patients.
