開心術で偶発的に巨細胞心筋炎と診断された1例

Incidental Diagnosis of Giant Cell Myocarditis at Open Heart Surgery：Report of Case

はじめに　心筋炎は感染，アレルギー，全身性疾患などに伴い発症する．特に経過が速く，心肺危機に陥り救命率が低いものを劇症型心筋炎と呼び，補助循環などの治療が必要になりうる．中でも巨細胞心筋炎（GCM）は非常にまれな原因不明の疾患である．われわれは，GCM罹患後の長期生存例に対する心臓手術を経験したので報告する．

Giant cell myocarditis （GCM） is one of the rare diseases that cause fatal heart failure and suspected to be associated with autoimmune disorder. There are few reports that the patients of GCM live long because of their progressive heart failure. We report a rare case of patient who was suspected two long hospitalizations due to heart failure in her childhood and peripartum period, and incidentally diagnosed with GCM by myocardial biopsy performed at the aortic valve replacement and mitral annuloplasty for severe aortic valve regurgitation and moderate mitral regurgitation.
