Congenital mitral valve stenosis (MVS) in children is usually isolated. However, it is, in rare cases, associated with secondary pulmonary hemosiderosis. It is hypothesized that secondary pulmonary hemosiderosis results from chronic pulmonary venous congestion and repeated microvascular hemorrhage due to elevated left atrial pressure. We describe the case of a six-year-old child with congenital severe MVS who developed coexisting pulmonary hypertension and hemosiderosis. The child was successfully managed with surgical repair of MVS through papillary muscle splitting and commissurotomy. This case illustrates the rare association between MVS and pulmonary hemosiderosis in a child with easy fatiguability and heart failure symptoms.
儿童先天性二尖瓣狭窄（MVS）通常为孤立性病变。然而，在罕见情况下，它会伴发继发性肺含铁血黄素沉着症。据推测，继发性肺含铁血黄素沉着症是由左心房压力升高导致的慢性肺静脉淤血和反复微血管出血引起的。我们描述了一名6岁先天性重度MVS患儿的病例，该患儿同时出现了肺动脉高压和含铁血黄素沉着症。通过乳头肌劈开和二尖瓣交界切开术对MVS进行手术修复后，患儿成功得到治疗。该病例说明了MVS与一名有易疲劳和心力衰竭症状儿童的肺含铁血黄素沉着症之间的罕见关联。
